The influence of tiller age and time of year on the growth of Themeda triandra and Sporobolous fimbriatus in semi-arid grassveld.

Abstract

Sequential growth measurements were made on successive populations of Themeda triandra and Sporobolous fimbriatus tillers initiated at different times of the year. The independent influences of tiller age and time of year on tiller growth were isolated by deriving growth indices for tillers of the same age at different times of the year and for tillers of all ages at each time of the year respectively.
