VISIBLE CHANGES OF CHARACTERS BY ALUMINIUM IN BRASSICA JUNCEA (L.) CZERNJ & COSSON

Abstracts

Aluminium ions exert their effect primarily on the root systems and decreased shoot growth is believed to be a later occurring effect. However, the effects on the aerial parts are not well documented. In our attempt to find a visible marked change of characters, an oil-yielding plant, Brassica juncea was grown in Al-applied soil (100-1000 µg g-1) at 4.5-5.0 pH. The aerial symptoms included inter alia purple patches in leaf margins, panicle collapse, but of interest was a change in colour of flowers from yellow to white in a few plants. Seeds produced by the white flowers were sown in the next generation and the results have been discussed.

SOMR RARE AND INTERESTING CHLOROCOCCALES FROM JABALPUR, MP

Abstracts

An illustrated account of four members of Chlorococcales is given. Of the four forms three are not only new to Jabalpur but are new records for India.

Very little is known about the Chlorococcales of Madhya Pradesh except Agarker (1953), Dikpoo and Agarker (1975), Shrivastav and Agarker (1974), Gupta and Nair (1962),  Sharma (1958),  Kulkarni (1978),  and Prasad (1961). But nothing is known about this group from Jabalpur except for a few casual references (Philipose, 1967).  With this end in view, a systematic study of the Chlorococcales of Jabalpur was taken up.  During the course of investigations as many as 77 species were collected. They are all new to this region and will be described in subsequent papers. However, three interesting species new to India and one rare one are being described.

EFFECT OF ALUMINIUM STRESS ON THE BIOCHEMICAL CONSITITUENTS DURING EARLY SEEDLING GROWTH OF MUSTARD

Abstracts

Studies were carried out to evanuate the effect of various concentrations (25, 50, 100, 200, 400 and 800 ug/ml) of different aluminium species on the biochemical constituents during seedling growth of mustard. The aluminium species chosen were AICl3,Al(NO3)3, and Al2(SO4)3. The first observable effect on plant was a limitation in root growth. Higher concentrations (beyond 100 ug/ml) resulted in the death of plants while concentrations ranging from 25 to 100 ug/ml resulted in a decrease in chlorophyll contents but an increase in soluble proteins and total phenol contents. The toxicity series was found to be AICl3> Al2(SO4)3 >Al(NO3)3.

IMPACT OF TOURISM AND HUMAN INTERFERENCE ON PTERIDOPHYTE – DIVERSITY IN SIKKIM, INDIA

Abstracts

Sikkim is a small hilly state and is part of the hot spots of biodiversity in the Eastern Himalayas. This state has luxuriant growth of ferns and fern allies. Due to its geographical position and scenic beauty it attracts tourists from all over the world. Influence of large number of tourists, lack of well-organized tourist guide’s organization, pollution generated by various means and human interference are causing the depletion of pteridophytes at an alarming rate. To conserve diversity of pteridophytes some conservational approaches like – development of ecotourism in a scientific way, formation of pteridophyte sanctuaries by in situ conservation of pteridophyte-rich areas and ex situ conservation via biotechnological approaches need to be established. Additionally, general awareness among local as well as visitors regarding importance of biodiversity conservation has to be repeatedly ensured.

BIOLOGY OF NATURAL AND FORCED MIGRATIONS

Abstracts

During past twenty thousand years, man has moved from caves to occupy all possible ecological niche: forests, mountains, river banks and sea shores. Man’s elastic adaptability is probably on account of architectural anthropology and blood genetics. Human Haemoglobin chains offer regulatory adaptability for reproductive biology by switching on and off regulatory genes during lifetime of each and every individual. Our haemoglobin chain configuration offers variable and flexible physiological adaptability (more so on account of HbF proportions in the adult blood). Practically, the evolution of blood physiology has inherently ensured physiological adaptability among all vertebrates, even among amphibians the proportion of gamma chains goes on responding to adaptive stresses. This paper on the basis of on going work reemphasizes on extensive studies to be carried out to understand influences of abrupt and natural migrations on changing patterns of foetal haemoglobin and adaptive significance among adults. Shifting of populations under compulsion may be increasing socio biological problems.

CHLOROPHYLL CONTENTS OF THE FIRST LEAVES OF INTACT AND DETOPPED VICIA FABA L. PLANTS

Abstracts

In Vicia faba L. the chlorophyll contents, the fresh weight and the life span of the lower leaves of detopped plants were greatly increased as compared with intact plants. Similar results were produced in kinetin-treated intact plants. IAA treatment appeared to lack such an effect. It appears that most cytokinins are synthesized in roots. The roots, though extensive, appeared to have no nutrient metabolizing effect. ABA induced very little chlorosis in lower leaves of detopped plants. When these leaves were treated with mixtures of IAA, kinetin, GA3, and ABA with or without sugars, none of these treatments degraded chlorophyll.

CHROMOSOMAL SCREENING ON FARM ANIMALS I. PRELIMINARY REPORT ON SHEEP AND COW

Abstracts

The farm animals Sheep (Ovis aries 2n=54; Slovak Merino Breed) and cattle (Cow, Bos taurus 2n=60; Cross Breed Holstein-Friesion) have been studied in order to evaluate cytogenetic suitability of their respective breed for future breeding programme.  We have encountered several chromosomal aberrations in the sheep as well as in Cow.  Sheep, besides acrocentric fusions, chromatid deletions show dicentric chromosomes and premature centromeric divisions. These are indicative of sterility. Similarly,  cow genome is characterised by prepondrance of Robertsonian translocation involving chromosome 1/29,  differences in X chromosome (Metacentric/Submetacentric) and centric fusions giving a aneusomatic counts 2n = 58-59,  instead of 2n=60.

ROOT-GALL NEMATODE DISEASE OF TOMATO (SOLANUM LYCOPERSICUM) AS AFFECTED BY ORGANIC MANURE/UREA FERTILIZER MIXTURE

Abstracts

Effects of organic manure/urea fertilizer mixtures on root-gall nematode disease on tomato were studied in a 3x4 factorial experiment in randomized complete block design with 4 replications. Urea fertilizer weights of 0.00, 27.8, 55.6, and 83.4kg/ha were separately mixed with fixed weights of 1.25 tons/ha of farmyard manure, municipal waste and pig slurry. Results showed that 27.8kg/ ha of urea fertilizer mixed with farmyard manure caused the tomato roots to be gall-free. The same was true of 83.4kg/ha of urea fertilizer mixed with municipal waste. Pig slurry mixed with 55.6kg/ ha of urea fertilizer caused the tomato plants to be rarely root-galled. Leaf area and number of leaves produced per plant increased as root-gall severity decreased. Significantly (P=0.05) higher number of harvested marketable fruits occurred on gall-free tomato plants treated with urea fertilizer mixed with farmyard manure at 27.8 kg/ha and 1.25 tons/ha respectively.

EFFECT OF MOISTURE REGIMES ON ANATOMICAL FEATURES AND STOMATAL BEHAVIOR OF SPECIES OF JUTE

Abstracts

Effect of moisture regimes and soil types on anatomy of stem and stomatal behavior of Corchorus capsularis (cv. CVL-1) and C. olitorius (cv. 0-4) were studied in pot culture. The soil moisture regimes were water/logged (WL), field capacity (FC), 60%, 40% and 20%, moisture of field capacity. Bark thickness, area of phloem pyramids were highest at FC and decreased significantly (P = 0.05) at 20% moisture of field capacity in both the cultivars. Number of fibre bundles and fibre bundle layers in the phloem wedge were highest at FC and shrank at driest treatment in both the cultivars. In general at WL condition fragmentation of phloem pyramids was observed in 0-4 plants. In contrast, in CVL-1 it was intact. The results suggest the sensitivity of 0-4 plants under waterlogged condition and the distribution of these species is related to the availability of water in the soil.

CLONAL EVOLUTION, IMMUNE RESPONSE AND CANCER

Abstracts

Beginning in 1964, observations of sunlight related phenomena in the skin of approximately 2000 subjects, mainly of European ancestry, were made in Sydney, Austalia (34° S. Lat.). Pigmented lesions were counted and many new relationships were indentified. The theory proposed to explain these relationships was of spontaneous or UVLinduced somatic mutation, with evidence of immune rejection responses to the benign or malignant tumours observed. A theory of initiation of tumour formation by somatic mutation of normal tissue differentiation genes was proposed: cells blocked from final differentiation might in many cases fail to recognize normal homoeostatic growth controls.

PHILOSOPHY, MATHEMATICS AND PHYSICS: A WORKABLE PARADOX !

Abstracts

The general view is brought forward that a mathematical view of nature can, in conjuction with modern physics, permit an understanding of resonance phenomena as they apply to human existence : Emotional, motivational as well associo-cultural phenomena may thus be understood as interactions between resonating chambers with characteristic frequencies. These effects may also show interaction with the continuum. Within the vedic Dharma, Karmic laws concerned with right action can be understood within a mathematico-physical postulation since the characteristic resonance effects of, for example,  benevolent caring versus aggressive rejectant motivational impulse would have amplification towards a central resonance frequency.

NODULATION IN COWPEA AS AFFECTED BY INTEGRATED NUTRIENT MANAGEMENT

Abstracts
Cowpea was grown at four levels of NPK (0,50,75,100% based on STR) without and with FYM @ 10t ha-1 in main plots under split plot design.  Sub plots were treated with four levels of bio-fertilisers (No inoculation, N2-fixers viz., Rhizobium in Cowpea, PSB and Rhizobium + PSB).  Observations at 45 days after sowing reveal that application of NPK up to 100% STR and addition of FYM @ 10 t ha-1 significantly increased the number of nodules per plant and its fresh and dry weight.  The highest number of nodules per plant and its fresh and dry weight was observed at 100% NPK level and 10 t ha-1 FYM respectively.  Similarly inoculation with Rhizobium and PSB alone or in combination significantly increased the number of nodules perplant and their weights with best results under dual inoculation.

PATTERN OF INHERITANCE OF RESISTANCE TO BACTERIAL LEAF STREAK IN RICE CULTIVARS

Abstracts
Genetic pattern of inheritance of resistance to bacterial leaf streak (BLS), a bacterial disease caused by Xanthomonas compestris  pv.  Oryzicola  was studied under artificial inoculation conditions in parents, F1  Plants, F2 population and F3  progenies in five cross combinations involving two indian rice cultivars viz. Bogzira 1 (BJ.1, resistant to BLS), NC 1281 (resistant) and one Philippine rice, Pankaj (Susceptible to BLS) using the bacterial isolate grown on semi synthetic potato-sucrosc-agar medium.  A simple and sure method was adopted for inoculation. The plants were scored for disease reaction and are classified as resistant (R) or susceptible (S) on the basis of colour, length, number and mode of distribution of lesions on the leaves.  A cross between NC 128i and B.J.1 resulted in 12R (NC 1281 Type);  3MR (BJ.1 type) and 1S segregates.  A ratio of 13:1 was realized from crosses involving resistant (R)/moderately resistant (MR) and susceptible (S) varieties and their reciprocal crosses. The appearance of susceptible class in F, and F, of a cross between NC 1281 and BJ.1 confirmed that B.J.1, till now considered to be resistant, is found to be moderately resistant (MR) to BLS, bearing leaves with long and unrestricted light brown coloured lesions. Segregation of F3 lines in to OR: IS, IR: 3S, 3R: IS, 3R:13S and IR: OS with non-significant chi square values in crosses-NC 1281 x Pankaj, Pankaj x NC 1281, B.J.1 x Pankaj and Pankaj x B.J.1 confirmed that resistance to BLS was governed by epistatic genes. Segregation of F3 of NC 1281 x B.J. 1 into IR: OMR: OS (true breeding R), OR: IMR: OS (true breeding MR), 12R:3 MR: IS, 3R: IMR: OS, 3R:OMR: IS, OR: 3 MR: IS and OR: O MR: IS (true breeding susceptible) ratio with chi square value of 2.26 further justified in classifying BJ.1 as moderately resistant variety.  Success of resistance breeding programme depends on the basic knowledge accumulated about the genetics of resistance.

Cytotoxic and phytotoxic effects of extracts of seven fern species were evaluated by pollen germination and seed germination bioassays respectively. All these species showed more or less inhibitory effects. Phytotoxic effects of ferns might be one of the reasons for their dominance in vegetation in the areas they grow. Cytotoxic potentials of ferns would be helpful in the development of antitumor drugs in future. Pollen germination bioassay for Screening cytotoxicity using Catharanthus roseus was found to be rapid and easy method like conventional root tip meristem cells test of garlic.

A NEW SINGLE NUCLEOTIDE POLYMORPHISM AND ONE – ALLELE SYSTEM FOR NLAIII-RELP IN EXON 6 OF LIVIN GENE

Abstracts

Livin is a member of the inhibitor apoptosis protein and overexpressed in a variety of Solid tumors and cancer cell lines, but its expression and clinical relevance are unclear. As exon 6 of the gene showed a new NlalII -RFLP, single nucleotide polymorphism, within codon 248 in one Philippine, allele frequencies of NlalII -248 polymorphism were studied in 200 chromosomes from 100 unrelated normal Korean individuals. As a result, only one allele system, the absence of the NlalII 248 site, was detected in Koreans.

Keywords :

Livin; Nlalll-RFLP; Single nucleotide polymorphism.

BIOGENIC SILICA (PHYTOLITH) PRODUCTION PATTERN OF COTYLEDONARY, FIRST TWO AND MATURE LEAVES OF HOLOPTELEA INTEGRIFOLIA PLANCH., SEEDLINGS

Abstracts

Holoptelea integrifolia Planch. is a large deciduous tree belonging to family Ulmaceae. Silica is absorbed in the form of monosilicic acid from the soil through their roots and become deposited in the cells of cotyledons, first two leaves and mature leaves. Silica is one of the most beneficial elements for all biological forms. It enhances the yield and quality of certain crops and help plants to overcome various biotic and abiotic stresses. Present study demonstrates the silica deposition pattern in cotyledons, first two leaves and mature leaves of H. integrifolia. In all three leafy forms silica is mostly deposited in the hairs, hair bases, tracheids, epidermal cells, and corkwarts. Hairs and hair bases are of different shapes and sizes in cotyledons, first two leaves and mature leaves of seedlings. Silicified hairs are unicellular, multicellular or glandular having smooth walls or armed with papillae. The highest frequency of silica deposition is found in mature leaves followed by first two leaves and cotyledons. These silicified hairs protect the plants against herbivores and check evaporation. They also inhibit the growth of pathogens and protect the delicate tissues from solar radiation.

PHENOLOGY AND REPRODUCTIVE BIOLOGY OF Adansonia digitata L: A THREATENED TREE SPECIES IN GWALIOR (MP) INDIA

Abstracts

Adansonia digitata L. (Malvaceae) is a threatened tree of high medicinal and nutritional importance. It has numerous biological properties including antimicrobial, antiviral, anti-oxidant and anti-inflammatory activities amongst others. Over exploitation and poor attention paid by the conservationists, the tree species in under great threat and may disappear soon. In order to develop strategies to conserve this valuable tree species, present study was undertaken to investigate its phenology and reproductive biology. The trees were completely devoid of leaves till the end of April. First vegetative buds appeared in the first week of May, followed by the initiation of floral buds. Flowering was initiated in second week of May and continued up to end of June. Peak flowering was observed in second week of June and Fruiting started in the second week of September and continued up to the first week of October. Flowers open in the afternoon between 12.00-02.00 hours, anther dehiscence between 02.00- 3.00 hours and stigma fimbriate-papillose lobes and become receptive 03.30 hours and remains receptive for one day. Present communication deals with the phonological events and reproductive biology of this highly prized tree species.

AIRBORNE POLLEN--FLORA IN AN OUTDOOR SITE IN GWALIOR (MP)

Abstracts

An aeropalynological survey was conducted for two years, between September 2012 to August 2014 by using “Burkard Portable Spore Trap Sampler” at Kampoo, an outdoor site at Gwalior (MP).  Total 33 pollen types were identified. The pollen grains belonged to angiospernic families. Dicotyledonous taxa contributed maximum number of pollen grains as compared to monocotyledons. Observations indicate that pollen of Poaceae was maximum followed by Asteraceae, Mimosaceae and Cassia type. On the basis of mode of pollination amphiphilous type of pollen were maximum followed by entomophily and anemophily. Total as well as individual pollen types and their number displayed distinct seasonal periodicity in their incidence.

GAMMA RADIOSENSITIVITY STUDIES ON ZINNIA ELEGANS VAR DREAMLAND

Abstracts

The success of induced mutagenesis technique using gamma rays in any crop or ornamental plants lies in the determination of optimum dose (LD₅₀). The study aims to determine the optimum dose of gamma rays in Zinnia elegans var Dreamland and the effect of different doses of gamma radiation on the germination and survival rate, plant height and root length. The seeds were treated with 10Gy, 20Gy, 50Gy, 75Gy, 100Gy, 125Gy, 300Gy, 400Gy and 500Gy at Bhabha Atomic Research Centre, Mumbai using ⁶⁰CO source. The results revealed that there was significant decline in the germination rate after ⁵⁰Gy gamma radiation dose and no significant variation in the survival rate until 300Gy as compared to the control. The LD50 for % germination and %survival was found to be 155.98 and 250.78. The higher gamma ray doses significantly decreased the plant height and root length. 40% reduction in shoot length and root length was found to be 250 to 260 and 210 to 220.

Keywords Zinnia elegans, gamma radiation, induced mutagenesis, radiosensitivity, LD₅₀.
