众所周知,许多外界因素都能影响水稻花粉的生活力,因此,在不良的外界条件下,常常引起花粉生活力减弱,授粉和受精率降低,产量下降,尤其是在杂交水稻制种时,由于是异花授粉,制种单产的高低往往与花粉的数量及其生活力强弱有着密切的关系。 有的研究指出,适量的激光与微波照射,能 It is well-known that many external factors can affect the viability of rice pollen. Therefore, under unfavorable external conditions, pollen viability is often weakened, pollination and fertilization rates are reduced, yield is reduced, especially when hybrid rice is planted Cross-pollination, the level of seed production is often linked with the number of pollen and its vitality has a close relationship. Some studies have pointed out that the right amount of laser and microwave irradiation, can
