Calcium chloride modification of cocoa seedlings response to water stress
Varying concentrations of calcium chloride (CaCl2) added to the growth medium of cocoa (Theobroma cacao) seedlings can modify their response to water stress. Leaves of CaCl2-treated seedlings were observed by the author to be turgid while those of control plants showed signs of wilting when both sets of plants were subjected to water stress. A decrease in transpiration rate of excised leaves of CaCl2-treated plants was observed in all treatments. It was suggested that the tolerance of treated plants to water stress might be due to a lowered rate of transpiration leading to improved Relative Water Content (RWC) which was observed to increase with increase in the concentrations of calcium chloride. The possible practical application of the finding of this investigation is proposed.
