摘　　要：对蓖麻(Ricinus communis L.)种子不同浸种时间与其出苗率等指标变化的相关性进行了调查研究。结果表明,蓖麻种子不同浸种时间与种子萌芽形成的总出苗数量和总出苗率之间呈极显著负相关,与其他指标之间的相关性不显著。对蓖麻种子不同浸种时间与总出苗数量、总出苗率和无苗窝率等指标进行二次曲线回归方程和直线回归方程的比较分析,结果表明蓖麻种子不同浸种时间与总出苗数量、总出苗率和无苗窝率等指标的回归方程都符合二次曲线回归方程。The correlation between the soaking time and the emergence rate of the seed of Ricinus communis L.was investigated and studied.Results showed that there was a significant negative correlation between the different soaking time of Ricinus communis L.seeds and the total number and rate of emergence of seeds,but no significant correlation with other indexes.The quadratic curve regression equation and linear regression equation were used to analyze the different soaking time,the total number of seedlings,the total rate of emergence and the rate of no nest of Ricinus communis L.seeds.The results showed that the regression equation of the different soaking time and the total number of seedlings,the total rate of emergence and the rate of no nest of Ricinus communis L.seeds were all in accordance with the quadratic curve regression equation.
