Abstract


In order to approach a reasonable method for the indirect estimation of the productivity in terrestrial plants, allometric method was studied with herbs, such as Boehmeria frutescens and Hibiscus mutablis, and scrubs, such as Robinia pseud oacacia and Morus alba f. Ilchiroe.
Allometric relations between D^2_30 H, square of the stem(or shoot) diameter (D_30) on 30㎝ height above ground multiplied by stem length (H), and the amount of the stem (Ws), or of the leaves per stem, were fitted to each material plant with linear regression.
The allometric coefficient in relation of D^2_30H to Ws was approximated between scrubs having different life form, and the allometric function in relation of D_F^2 to W_L was common between herbs in spite of having different growth habitat.
As the allometries between D^2_30H and W_S or W_L were changeable with the seasonal change it function should be calculated repeatedly whenever investigating the standing crop of such community.
It is able to utilize an indirect value of D_30 obtained from the allometry between D_30 and H because direct measurement of D_30 in the field is accompanied by troublesome and waste of much time.
