摘要: This work was performed aiming to evaluate the growth of neem seedlings (Azadirachta indica A. Juss.) under water deficit. The experimental design entirely randomized, with seven treatments (100, 80, 60, 40 and 20% field capacity, without re-watering). height, number leaves stem diameter were analyzed weekly. At end experiment, dry matter leaves, shoots, roots, root shoot ratio biomass allocation in leaf, roots determined. Leaf area, leaf area specific also calculated. Water stress reduced plants several treatments. matter. Only reduced. reduced; however, there not significant differences for area. recovery re-watering evident by emitting new leaves. results suggest that must be cultivated, initial phase development, 80% maximum production.
