Elevation of shoot-apices of two ecotypes of Themeda triandra on the Transvaal Highveld

Abstract

In a series of investigations from 1965 to 1970 on the Transvaal Highveld it was found that the elevation of shoot apices of two ecotypes of Themeda triandra was affected by season, ecotype and treatment. The absence of defoliation increased the susceptibility of the ecotypes to defoliation, whereas the shorter the defoliation the greater the subsequent resistance to grazing. The most important finding was the general application of earlier research findings from Natal was not possible in this case.
