Effect of Water Stresses on Growth Attributes in Jute I. Plant Height

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

Abstract: The plant height was studied in Corchorus capsularis (cultivars D-154 and CVL-1) and Corchorus olitorius (cultivars O-4 and R-26) grown under various water regimes. The cultivars were 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. On the tolerance of submersion, the test cultivars could be placed as D-154 > CVL-1 > R-26 > O-4. The plants of CVL-1 became shorter than that of the O-4 in constant drought. On the contrary, the plants of O-4 and R-26 became shorter than that of the CVL-1 and D-154 in standing water conditions. The plants of O-4 and R-26 died earlier when they were exposed to standing water condition in young stage compared to those of the CVL-1 and D-154. It appears that the plant height is highly affected by constant drought in case of Corchorus capsularis and by standing water in case of Corchorus olitorius. The stressed plants of all the cultivars are shorter than their corresponding control plants.
