应用灰色关联度分析影响水稻空秕率的生理因素

ANALYSIS OF EFFECT OF PHYSIOLOGICAL FACTORS FOR STERILE GRAIN OF RICE WITH GREY CORRELATION

本文应用灰色关联度分析法，对水稻灌浆过程中穗部主要生理因素间的相关性及其对水稻空秕率的影响进行了分析．明确了各因素在影响水稻空秕率中的作用．为水稻高产栽培和新品种选育提供了理论依据．

Based on the Grey system theory,the paper analysis the correlation of major physiological factors in grain filling of rice and the effect of major physiological factors for rice sterile grain rate,indicates the function of every physiological factor in the influencing sterile grain of rice,provides theoretical basis for breeding and high yield culture of rice.
