Shade Inhibits Leaf Size by Controlling Cell Proliferation and Enlargement in Soybean
Abstract To gain more insight into the physiological function of shade and how shade affects leaf size, we investigated the growth, leaf anatomical structure, hormones and genes expressions in soybean. Soybean seeds were sown in plastic pots and were allowed to germinate and grow for 30 days under s...
