中文摘要:

小麦雄蕊心皮化指小麦的雄蕊向雌蕊或类似雌蕊的结构同源转化的现象。雄蕊完全心皮化后可正常结实，增加小麦穗粒数，提高小麦产量。雄蕊不完全心皮化可导致雄性不育。本文介绍了小麦的花发育过程、小麦花器官发育模型及同源异型突变以及目前获得的4份小麦雄蕊心皮化材料，解析了导致小麦雄蕊心皮化的调控机制及乙烯对小麦雄蕊心皮化的影响，为小麦花发育的研究提供参考，也为小麦的遗传改良及分子设计育种提供理论依据。

英文摘要:

Wheat stamen pistillody refers to the phenomenon of homologous transformation of wheat stamens into pistils or pistil like structures. The stamens can be normally seeded after complete pistillody, which increases the number of grains per spike and yield of wheat. Incomplete pistillody of stamens leads to male sterility. In this paper, the flower development process of wheat, wheat floral organ development model and homeotic mutantion, as well as the four kinds of wheat stamen pistillody materials obtained at present were briefly introduced, the regulatory mechanism leading to stamen pistillody of wheat and the effect of ethylene on stamen pistillody of wheat were analyzed, which provides a reference for the study of wheat flower development, and also provides a theoretical basis for genetic improvement and molecular design breeding of wheat.
