摘要
通过对紫花地丁(Viola philippica Cav.)种子产量构成因子做方差、相关和回归分析,找出呼和浩特地区紫花地丁种子产量构成因子中的限制性因子是每株结荚数和每荚种子数;预测栽培紫花地丁单株实际种子产量的模型为:Y=-0.746+0.047 X3+0.025 X5。利用种子产量构成因子计算潜在种子产量和实际种子产量。
Seed yield componentswere analyzed. The variance,correlation analysis,and regression analysiswere done in the seed yield components of Viola philippicaCav. The results showed thatthe numberof seed pods of perplant and the number of seeds of each pod are the most important in seed production. The model of actual seed yield perplant of Viola philippicaCav is：Y= -0. 746 ＋ 0. 047X3 ＋0. 025X5. Potential and actual seedsyieldwer- eestimated based on seed yield components.
