Effect of Water Stresses on Growth Attributes in Jute II. Plant Base Diameter

A.K.M. Azad-ud-doula Prodhan, M.L. Rahman and M.A. Haque    

Abstract: The plant base diameter was studied in Corchorus capsularis L. (cv. CVL-1 and D-154) and Corchorus olitorius L. (cv. O-4 and R-26) grown under constant drought, constant saturation, alternate saturation and drought, and different levels of standing water (5 cm, 10 cm, 20 cm and 30 cm) conditions. The cultivar O-4 had been found to be tolerant to drought but susceptible to waterlogging condition, particularly at the young stage of growth. On the descending order of base diameter and tolerance of submersion, the test cultivars could be placed as CVL-1 > D-154 > R-26 > O-4. The base diameter of CVL-1 plants decreased in constant drought condition as compared to that of O-4 plants. At the age of 90 days, the decrease in base diameter in CVL-1 plants was doubled compared to that of O-4 plants. On the contrary, the base diameter of O-4 and R-26 plants decreased in standing water condition compared to that of CVL-1 and D-154 plants. The CVL-1 plants died earlier in constant drought. The O-4 and R-26 plants died earlier in standing water condition compared to CVL-1 and D-154 plants. It appeared that the base diameter highly affected by standing water in case of Corchorus olitorius and by constant drought in case of Corchorus capsularis. The base diameter of all the stressed plants decreased in comparison with those of control plants.
