苦碟子生物量与其株高的相关性分析

Correlation Analysis of Biomass and Plant Height of Ixeris sonchifolia

采用大样本、随机取样方法分析了通化市苦碟子生物量与其株高的相关性。结果表明:苦碟子植株高度与植株干鲜重呈密切的正相关,其相关程度最佳的均为指数函数,即苦碟子植株干鲜重均随着植株高度的增长呈指数函数形式增长。植株鲜重总变异数受植株高度的影响比植株干重总变异数受植株高度的影响大。

Large and random sampling methods were adopted to analyze the correlation of biomass and plant height of Ixeris sonchifolia in Tonghua City.The results showed that the plant height and its fresh and dried weight had high positive correlation,the optimal degree of correlation was exponential,that is to say with plant height increased,the fresh and dried weight also increased by exponential.The effect of plant height on total coefficient variation of fresh weight is much greater than its on plant dried weight.
