Abstract: The panicle weight (we) of rice plant and the total weight of aerial parts (wb) are positively and closely correlated. In fields of ordinary densities this relationship may be expressed by a linear regression we = b (wb– a) (1) according to Wang and Lei (1961). In the present experiment, analyses were made on the correlationships between the different organs and how these correlations are influenced by various factors such as planting density, artificial thinning and manuring. The results are summarized as follows: 1. In all the treatments, except artificial thinning, equation (1) expresses well the we wb relationship. The parameter b varies very little in these treatments, but variation of parameter a is considerable. 2. In very sparsely planted plots or artificially thinned plots, the we wb relationship is not strictly linear (fig. 1 & 2). For very large wb's, the observed values of we are lower than the values calculated from the linear equation. The relation is better expressed by the formula we = b (wb–a)c (4) . The significance of equation (3) as a generalized equation of the equation (1) and the classical allometric growth equation (y = b xc) is discussed.
