Analysis of Plant Type in Lasiurus Sindicus Henr

Abstract

Internode patterns in 18 genotypes of Lasiurus sindicus grown in a replicated trial were analysed by using the ideograph technique. Six patterns were recognised depending upon the patter n of change of relative size of the successive interonodes from the base upwards. A few genotypes exhibited only one growth phase e.g. accelerated growth, while others exhibited a combination of any two or three growth phases e.g. accelerated, uniform and retarded Genotypes differed in the presence of one or more growth phases and their sequence. The genotypes with two or more growth peaks had higher dry matter yield than those with single or no growth peak. The utility of different internode patterns from the point of view of association with forage yielding ability and leaves position has been discussed.
