Evaluation of 14 native pastures of high Andean of Bolivia

Abstract

The objective of this research was to evaluate 14 accessions of native grasses from the high Andean region of Bolivia and identify versatile and strategic species for the Bolivian Altiplano. The study consisted of two phases: the first phase involved determining the germination percentage in a seed laboratory, and the second phase was conducted in a greenhouse to evaluate plant height, leaf length, and number of leaves. The analysis of variance revealed significant differences (P < 0.01) among the accessions in the assessed characteristics. The biplot analysis indicated a strong positive correlation between the number of leaves and plant height, with plant height also being related to leaf length. Among the accessions, BOL-01_BU (Bromus catharticus) stood out for its high germination percentage and vegetative development, while BOL-01_HM (Hordeum muticum J. Presl) displayed versatile characteristics in terms of plant height, leaf development, and high nutritional value.
