-3/2方自疏法则的机理与普适性

根据植物构件性理论，对经验规律-3/2方自疏法则进行了理论推导，对-3/2方自疏法则以前不能解释的实验结果进行了理论分析，并以春小麦（Triticum aestiunm L.）为材料，设置了4个密度梯度的实验，定期测定个体形态及种群数量指标，证明了-3/2方自疏法法则对春小麦作物种群的适用性，同时，基于所测定的植株形态数据，结合数值的量纲变化特点对-3/2方自疏法则的普适性进行了理论解释。

Mechanism and universality of Yoda's -3/2 law of self-thinning in plant population

According to plant modular theory, the Yoda's -3/2 law of self-thinning was theoretically rederived in this paper. With the parameters in the expression of Yoda's -3/2 law being given biological meanings, this article offered universal and rational explanations for relevant data in literatures that could not be explained before. Based on the authors' hypothesis, the experiments on the self-thinning process of spring wheat ( Triticum aestivum L.) were conducted. Individual morphological and population quantitative indexes were examined at regular intervals. The results showed that the self-thinning process of spring wheat conformed to Yoda's -3/2 law of self-thinning. At the same time, the universality of Yoda's -3/2 law of self-thinning was explained theoretically by analyzing individual morphological data.
