摘    要:小偃54是一个具有杂种优势、品质优良的小麦品种。通过在豫南试种、示范及对其生理机制探讨发现:它有发达的根系,可在逆境中充分吸收营养、水分等,以满足自身营养需要和加大蒸发量,以调解渍水及旱灾条件下的生理功能和提高抵御病、旱、涝、倒伏等自然灾害的抗逆能力;具有旗叶中等、旗叶上挺的特征,因此通风透光较好,冠层温度较低,具有较高的抗干热风能力。此外,它是蛋白质含量很高的优质小麦,又是氮高效基因型,既能在逆境胁迫下充分吸收营养,又能用自身能量维护渍水条件下的生存需要,同时它又是属于高效低营养基因型。尤其适合在低磷协迫下利用其自身遗传生理特性去活化吸收营养,调解抗逆能力,获得较高产量。

关 键 词:小偃54  抗逆性  抗逆能力  蛋白质含量  杂种优势  小麦品种  品质优良  生理机制  营养需要  生理功能  自然灾害  通风透光  冠层温度  优质小麦  逆境胁迫  活化吸收  生理特性  基因型  蒸发量  干热风  高产量  渍水  调解  旗叶  高效  试种

Abstract:Xiaoyan 54 wheat is of high quality and has an advantage of crossbreed. By planting experimentally and researching its physiological mechanism we find that: It owns well-developed rootage, which can absorb enough nutrition and moisture in adversity so as to meet its own's nutrition need, increase the evaporation capacity, regulate physiological functions in disastrous condition, and enhance the ability to resist disease, drought, water logging and lodging; This wheat leaf has good ability to ventilate and absorb light, and the temperature in its coronal is low, so it is rather capable of resisting dry sirocco.
Keywords:Xiaoyan 54 wheat  Rootage character  Functional leaf speciality  Alimentation efficiency
