通过对龙特浦A自交结实特性的分析 ,认为龙特浦A自交结实率的高低与花粉黑染率的高低有关 ,黑染花粉主要来自颖花内的黄花药 ,而空气湿度影响了黄花药散粉 ,甚至也加速了黄花药的败育进程。所以较高的湿度会明显降低龙特浦A的自交结实率 Based on the analysis of the fruit self-fertility of Longtepu A, it is concluded that the self-fertility rate of Longtepu A is related to the pollen-black rate. The black-stained pollen is mainly derived from the yellow anthers in the spikelet and the air humidity affects Yellow powder loose powder, and even accelerated the abortion process of the yellow anthers. Therefore, higher humidity will significantly reduce Longtepu A self-fertility rate
