杂交稻的广泛应用,使我国稻作生产在不少地区获得了明显增产,但有些地区由于杂交稻生育期较长,或者还不能完全适应当地气候条件等原因,以致尚不能得到预期的增产效果。因此查明杂交稻及其亲本的光周期反应特性和温度的光周期效应,不但有助于深入了解水稻光周期性的遗传基础,而且也有利于农业生产实践中进一步应用好杂交稻。进行光温反应的试
The widespread use of hybrid rice has led to significant increase of rice production in many areas in China. However, in some areas, the expected yield-increasing effect can not be obtained due to the longer growth period of hybrid rice or the inability to fully adapt to the local climatic conditions . Therefore, it is not only helpful to understand the genetic basis of photoperiod of rice, but also to further utilize the hybrid rice in the practice of agricultural production by identifying the photoperiod response characteristics and temperature photoperiod effects of hybrid rice and its parents.
