春大豆主要农艺性状的相关分析

以11个新疆春大豆品种为材料研究生育期之间,主要农艺性状之间,开花期、结荚期和鼓粒期的叶绿素含量与单株粒重之间,以及品质与单株粒重之间的相关性;苗期及盛花期显著正相关,结荚期与盛花期显著负相关,主茎节数、单株荚数、单株粒数及茎粗与单株产量显著正相关;开花期、结荚期和鼓粒期的叶绿素含量与单株粒重呈负相关,这可能与环境影响有关;粗蛋白、粗脂肪均与单株产量呈正相关.

Correlation Analysis of the Main Agronomic Characters in Spring Soybean

In the article,we studied 11 spring soybean cultivars about the correlation between the seed weight per plant and growth stage,main agronomic characters,chlorphyll content of blooming stage and pods stage pod-filling stage,and the correlation between the seed weight per plant and quality;the positive correlation was found between seedling and florescence;pod stage is negatively correlated with florescence.The seed weight per plant is positively correlated with nods on main stem pods per plant,seeds per plant and diameter of stem;the seed weight per plant is negatively correlated with characters,chlorophyll content of flowering stage,pods stage and pod-filling stage.This may related with around conditions.The seed weight per plant is positively correlated with protein and fat content.
