title: [Mechanism and universality of Yoda's -3/2 law of self-thinning in plant population].
abstract: 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.
