The Effect of Calcium on Elongation in Hypocotyl Segments of Soybean Sprouts
|
|
|
|
|
Abstract
|
|
|
Hypocotyl segments of shade-grown soybean sprouts (var, Kumdo) were floated in solutions containing various substances and kept for 72 hours at approximately 25℃ of laboratory conditions. Increase in hypocotyl elongation was thus obtained as a measure of the present experiments.
Calcium at the physiological level inhibited the clongation of hypocotyl segments, while potassium promote it. The action of calcium was further enhanced by, a slight addition of boron. Although IAA and GA respectively promoted the elongation over the control, an addition of calcium to them resulted in reduced degree of their promotive effects.
