摘要: Aims Sorghum is commonly grown under dryland conditions, where yields are limited by soil water deficits. Yield increase may be possible selecting genotypes that express traits desirable for water-limited conditions. Water conservation one trait increasing yield since this could availability during critical stages of crop development. achieved slower transpiration rate with drying initiated at a high fraction transpirable (FTSW) so the use extended over longer period time. This strategy allow to have available phase grain filling. Therefore, objective study was compare sorghum differences in threshold decline transpiration.
