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.
