Crecimiento Y Establecimiento De Plántulas De Bouteloua gracilis (Kunth) Lag. ex Griffiths Y Eragrostis curvula var. conferta Stapf Bajo Un RéGimen Simulado De Lluvia

Abstract

The effect of a simulated-rain regime was evaluated on the development and seedling establishment of blue grama Bouteloua gracilis, and boer lovegrass (Eragrostis curvula var. conferta) under greenhouse conditions. A group of seedlings was maintained under waterings to field capacity while another group of seedlings was maintained under a simulated-rain regime; the regime was simulated from real climate records registered in a weather station located near the site where the seeds were collected. Every 3 d, the number of leaves, tillers, and seedling height was measured. 37 d after seedling establishment, root and tiller dry weights, and root to shoot ratios were determined. B. gracilis seedlings developed more tillers per seedling The effect of a simulated-rain regime was evaluated on the development and seedling establishment of blue grama Bouteloua gracilis, and boer lovegrass (Eragrostis curvula var. conferta) under greenhouse conditions.
