不同遗传系统(核质组成)在同一试验条件下,其胞质所处的生理状况不同,具体表现在它们对外界环境的适应和利用能力上的差异.对特定组合来说,适宜的栽培条件能通过改善水稻自身的遗传平衡,增强自动调节的能力,克服胞质的不良影响,使剑叶含氮量提高,功能期延长,净光合效率提高,ATP 酶活性增强,过氧化物酶活性减弱,从而获得高产.因此研究杂交水稻的区域生态适应性及相应的高产栽培技术很重要.
Different genetic systems (nuclear component) under the same experimental conditions, the cytoplasm of the physiological conditions are different, specifically in their ability to adapt to the external environment and the ability to use for a specific combination, the appropriate cultivation conditions Can overcome the adverse effects of cytoplasm by improving the genetic balance of rice and enhancing the ability of self-regulation, thus increasing the nitrogen content of flag leaves, prolonging the functional period, increasing the net photosynthetic efficiency, increasing the activity of ATPase and decreasing the activity of peroxidase So as to obtain high yield.Therefore, it is very important to study the regional ecological adaptability of hybrid rice and corresponding high-yielding cultivation techniques.
