VARIETAL VARIATION IN MORPHOLOGY AND GROWTH OF GROUNDNUT

Abstract

Morphological characteristics determining plant form associated with "source" quantum, distribution of dry matter and growth analysis of plant were examined in detail as time trend phenomena. Leaf weight, number and area are distinct for each habit of growth of which leaf weight alone is significantly positively correlated with pod yield even as total dry matter production, when all the varieties are pooled irrespective of habit. But at habit level, the significant positive association is not sustained by virtue of smallness of population size and the extent of heterogeneity of varieties. Depletion of dry matter from leaf rather then stem during development symbo- lishes bunch, depletion from leaf but much more from stem marks out semi-spreading and an accumulation of dry matter in leaf but large depletion from stem chara- cterises spreading and the yield ranking is linked to the quantum of depletion Growth analysis comprising NAR, RGR, CGR and LAI are considered and the im portance of LAI has become conspicuous having a control over CGR.
