每荚粒数是构成豌豆产量重要因素之一。据相关性测定,单株粒重和每荚粒数为正相关,其相关系数γ=0.56。说明每荚粒数愈多,则单株产量愈高。每个豌豆品种的每荚平均胚珠数是一定的,不因环境条件的改变而产生大的变化。而每荚粒数的多少,是受种子的败育性所制约的。我所豌豆组测定种子败育百分率和每荚粒数,单株粒重都是负相关,其相关系数(γ)分别为-0.87和-0.54。说明种子败育率愈高,则每荚粒
The number of pods per pod is one of the most important factors in making pea yield. According to the correlation analysis, the grain weight per plant was positively correlated with the number of grains per pod, and the correlation coefficient γ = 0.56. Explain that the more grains per pod, the higher the yield per plant. The average number of ovules per pod for each pea variety is constant, without major changes due to changes in environmental conditions. The number of pods per pod is controlled by the abortion of the seed. The percentage of seed abortion in the pea group was negatively correlated with the grain weight per pod and the grain weight per plant. The correlation coefficient (γ) was -0.87 and -0.54 respectively. That the higher the rate of seed abortion, then every pod grain
