野败型不宵系稻穗开颖迟、闭颖慢的原因与其浆片中维管束数目少、导管和维管束薄壁细胞不发达有关。闭颖过程受小穗轴控制,并受温度影响,而与受精过程无关。水稻颖花能在水中开闭。
The reason for late opening and late closure of the wild-type rice varieties was that the number of vascular bundles in the pulp was small, and the undeveloped duct and vascular bundle parenchyma cells. The closed process is controlled by the spikelet axis and is affected by temperature, but has nothing to do with the fertilization process. Rice spikelets can be opened and closed in water.
