小麦穗形态建成和生理特征及外界影响因素的研究进展
Research Progress on Morphogenesis,Physiological Characteristics,and Its External Influencing Factors in Wheat Spike
摘要
Abstract
Wheat is an important food crop,with its global planting area ranking first among the three major food crops.The final grains per spike and yield are determined by the morphogenesis of the spike,which is a crucial organ for wheat yield formation.At the same time,outside environmental factors also have an impact on this process.The glumes,rachis,and awns of spikes are among the tissues with the ability to photosynthesize,and the results of this process are crucial for the development of grain yield.This article expanded two aspects around morphological structure and physiological function in wheat spike,and it reviewed the structure,development process,and external environmental factors that affect the development of spike organs.It summarized and analyzed the photosynthetic contribution of spike organs and their impact on grain filling and material enrichment.Meanwhile,the corresponding relationship between the structure and function of spike organs were discussed,and reasonable regulation of ear differentiation has been discussed to promote the photosynthetic capacity of spike and increase the number and weight of grains per spike.The results provide reference for enhancing the yield potential of wheat.关键词
