Putrescine and deficit irrigation as regulatory factors in basil plants metabolism and morpho-physiology

The purpose of this study was to alleviate the harmful effects water restriction, by applying foliar doses putrescine (0, 50, 100 and 150 mg L-1) on basil plants, as well as, understand different soil levels (60% 80% capacity) plant development. We evaluated physiology metabolic pathways plants. Basil plants under restriction reduced their growth dry matter accumulation, leaf status, physiological variables, photosynthetic pigments. Furthermore, exogenous sprays, influenced biometric pigments, proline levels. Our research suggests that sprays promote behaviours spp., through activation tolerance mechanisms in moderate deficit, principally accumulation leaves. Moreover, oil chemical profile determined availability soil.
