Description
The initial development analysis is destinated to the evaluation of net production in plants, derivated from the photosyntetic process and the perform results of the assimilative system during certain time period (Watson, 1952). The factors that guide plant production, in general, may be classificated in three classes : genetic, ecological and physiological factors. The physiological factors are : leaf area index (LAI), net assimilation rate (EA) and relative growth rate (Rw) (Alvim, 1962). Some authors think that little genetic difference exist in relation to EA and that there is a little probability of increasing the production capacity of species through plant's selections for higher EA (Watson, 1952). However, appreciable differences have been found among species (Alvin, 1962), as well as within species (Watson, 1952). The purpose of this essay was to verify the different development among cultivars and species of different grasses and forage legumes.

Study of Forage Plants' Initial Growth using the Quantitative Development Analysis
The initial development analysis is destinated to the evaluation of net production in plants, derivated from the photosyntetic process and the perform results of the assimilative system during certain time period (Watson, 1952). The factors that guide plant production, in general, may be classificated in three classes : genetic, ecological and physiological factors. The physiological factors are : leaf area index (LAI), net assimilation rate (EA) and relative growth rate (Rw) (Alvim, 1962).
