• L.N.VYAS, R.K.GARG and M.P.S.RANAWAT (Dept. of Botany, School of Basic Sciences and Humanities. University of Udaipur and Dept. of Biology, Lambardar Higher Secondary School, Udaipur) Observations on the dry matter production in Mitragyna parvifolia Korth. Jap. J. Ecol. 21,227-230 (1971) Estimation of dry matter production in Mitragyna parvifolia Korth is presented. The area of study, Borimalan block in the Prasad range, is 54 kms south of Udaipur town (24°11'N and 73°42'E). From the study it is concluded that : - (i) The girth (G), branch dry weight (BDW), tree height (Th), total plant biomass and photosynthetic area increase with an increase in the number of growth rings (x). The regression equations obtained are-G=-34.81+2.674x (for bole), G=-1.416+2.4x (for branches), BDW=-14.00+2.37x, Th=-0.65+0.328x. (ii) The net above ground biomass production in this tree species varies between 659-3424 kg/ha. (iii) The average increment in non-photosynthetic above ground biomass ranges from 1.5 kg/tree/yr. to 8.85 kg/tree/yr. The increase is gradual up to 30 growth rings, followed by a sudden rise from 30-35 growth rings and a decline afterwards.
