美国内布拉斯加大学遗传育种研究所培育出一种耐旱大豆的新品种。这种大豆是用中国野生大豆与美国西部的普通大豆杂交后培育的。它的特点是叶片上的白色叶毛比普通大豆叶片上的叶毛多3倍多,浓密的白色叶毛可以反射强烈的阳光,因而减少了叶面水分的蒸腾。经试种表明,耐旱大豆所需水分比一般
Institute of Genetics and Breeding, University of Nebraska, United States to cultivate a new variety of drought-tolerant soybean. The soybeans were cultivated using a combination of Chinese wild soybean and common soybean in the western United States. It is characterized by more than three times more white leaves on the leaf than leafy leaves on a common soybean leaf, and thick white leaf hairs reflect intense sunlight and thus reduce the transpiration of leaf water. The test shows that drought-tolerant soybean water required than the average
