A Study on Florets Differentiation, Development and Degeneration in Winter Wheat

doi:10.7668/hbnxb.1996.02.002

Abstract

Abstract: The study showed that the floret development period could be divided into eight stages, such as floret primordium formation stage, stamen and pistil primordium formation stage, anther elongation stage, feathery stigma formation stage, and anther yellowing stage. Therefore, we could discriminate the floret development stages more directly and precisely. The active accumulated temperature above 10℃ showed linear correlation with the floret development period. The floret degenerative process began at the ovary wall hairs elongation stage and ended at the feathery stigma formation stage. The degeneration florets mainly were located on the base and uppper spikelets.

Key words: Wheat Floret differentiation and development and degeneration, Active accumulated temperature
