各种高粱栽培品种的氮利用率Ｊ．Ｃ．Ｇａｒｄｎｅｒ等对形态、解剖和生理因素综合对改进氮利用率（ＮＵＥ）所起的作用所知甚少。已适应低氮条件的地方栽培品种与当代选育的品种相比具有不同的抗逆境机能（Ｐｅａｒｓｏｍ，１９８５）。抗氮胁迫的生理过程常与叶面积和气...
Nitrogen utilization rates of various sorghum cultivars J. C. Little is known about the role of synthesis of morphological, anatomical, and physiological factors in improving nitrogen use efficiency (NUE) by Gardner et al. Local cultivars that have been adapted to low nitrogen conditions have different resistance to stress than contemporary breeding (Pearsom, 1985). Anti-nitrogen stress of the physiological processes often associated with leaf area and gas ...
