Acumulación de forraje, composición morfológica e intercepción luminosa en trigos (Triticum sp.)

Abstract

The objectives of the study were to perform the fodder accumulation curves and morphological components and light interception to determine the optimal moment of cutting for green fodder of three lines and one wheat variety (Triticum sp.). Harvests were performed at intervals of 7 d, 43 days after sowing (DAS). In each harvest the average height of 20 plants was recorded, the intercepted radiation (IR), dry matter accumulation, morphological composition, and leaf area index (LAI). The sampling unit was a square of 0.45 m2.
