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

In pot culture, the effects of moisture regimes and soil types on stem morphology and stomatal behaviour of Corchorus capsularis (cv. CVL-1) and Corchorus olitorius (cv. 0-4) were investigated. Water/logged (WL), field capacity (FC), 60 percent, 40 percent, and 20 percent moisture of field capacity were the soil moisture regimes. In both cultivars, bark thickness and area of phloem pyramids were maximum at FC and dropped significantly (P = 0.05) at 20% moisture of field capacity. In both cultivars, the number of fibre bundles and fibre bundle layers in the phloem wedge was maximum at FC and declined at the driest treatment. In general, fragmentation of phloem pyramids was found in 0-4 plants under WL conditions. CVL-1, on the other hand, had it intact. The findings imply that 0-4 plants are sensitive to waterlogging and that the distribution of these species is linked to the availability of water in the soil.
