一、抗旱性的原理和生理效应及其签定 Genkel’ P.A.(Henckel,P.A.)(1982)进行作物抗热抗旱性试验。其签定抗性的方法,是根据于在热、旱处理条件下根部平衡石(statolith)淀粉的水解作用。品种抗旱性愈强,水解作用进行得愉慢,使有机物的合成积累增多。已知抗旱在生理上系由于在干旱条件下能增大细胞原生质的粘度及细胞液浓度。以致增多亲水胶体及结合水,则原生质不易因脱水而破坏和衰老,能维持正常的代谢作用。此法在该试验的小麦和菜豆上得到验证。
First, the principles of drought resistance and physiological effects and its signature Genkel ’P.A. (Henckel, P.A.) (1982) for crop drought resistance test. Its resistance is based on the hydrolysis of starch statolith in the heat and drought conditions. The stronger the drought resistance of varieties, the slower the hydrolysis, so that the accumulation of organic synthesis increased. It is known that drought resistance is physiologically due to increased cell protoplast viscosity and cytosolic concentration under drought conditions. Resulting in increased hydrophilic colloid and water, the protoplasm is not easy due to dehydration damage and aging, can maintain normal metabolism. This method was validated on the wheat and beans tested in this experiment.
