不同密度玉米品种雌雄穗开花间隔与产量相关性的研究

Study on the Correlation Between the Anthesis-silking Interval and Grain Yield of Maize in Different Planting Density

以8个不同株型玉米品种为试验材料,采用4种不同密度进行试验。结果表明,种植密度不同影响玉米雌雄穗开花间隔,同时,雌雄穗开花间隔与产量因素、产量有一定相关性,这种相关性随密度不同而不同。

Eight maize varieties of different plant type were planted in four kinds of plant densities.The results showed that the different plant density had.Effect on anthesis-silking in-terval(ASI)and the anthesis-silking interal(ASI)is correlated to characters of yield component and grain yield of maize,this kind of correlation was not same under different plant density.
