摘要
渝矮籼型核不育水稻,由于花药毡绒层细胞在单核期间迅速解体,造成花粉营养供应障碍而导致败育,属典败型花粉。
The pollens of Chongqing dwarf male-sterile rice belong to an abortim type. Pollen abortion occurs mainly at the one-nucleus latter stage in pollen development process. It is a typical abortion type. The nutrition obstacle of pollen causes abortion because the tapetum cells of authers disintegrate rapidly at one-nucleus stage.
