苏联不同地区小麦的稳产丰收,同提高品种的耐旱性有关。育种是有效解决这一问题的主要途径。生理机制对小麦品种固有的耐旱水平的发挥有时起着决定作用。因此,面临的一项重要任务就是探索将生理学研究成果直接用于育种 The stable yield of wheat in different parts of the Soviet Union is related to improving the drought tolerance of the varieties. Breeding is the main way to effectively solve this problem. Physiological mechanisms sometimes play a decisive role in the development of drought tolerance levels inherent to wheat cultivars. Therefore, an important task facing us is to explore the direct use of the results of physiological research in breeding
