研究玉米雌雄穗分化过程及其与外部形态的关系,对于制定丰产栽培技术措施,特别是经济合理施肥具有重要意义;对于从理论上探讨杂交优势的规律及受精生物学的机制等也很有价值。国内外开展这方面的研究已经有几十年的历史,但一般都以春玉米为材料,套种玉米的雌穗分化过程尚未进行过
Studying the differentiation process of male and female maize and its relationship with external morphology is of great significance for the formulation of high-yield cultivation techniques, especially for economic and rational fertilization. It is also valuable for theoretically exploring the rules of hybrid vigor and the mechanism of fertilization biology . Domestic and foreign research in this area has been decades of history, but usually spring maize as a material, intercropping corn spike differentiation process has not been carried out
