The climate unpredictability causes long periods of drought, becoming the main risk factor in soybeans production fields and consequent losses to farmers Brazil worldwide. As sessile organisms, plants are constantly challenged by a wide range environmental stresses, including drought. Growth constraints stress due these changes result reduced yield significant harvesting losses. response abioti...

In the sub-tropics, water and nitrogen are the most important factors limiting the grain yield of maize. The effect of nitrogen (N) rates and drought stress at different growth stages of maize were investigated. Nitrogen treatments consisted of 100, 150, and 200  kgN.ha-1 from the urea source while water stress treatments were composed of irrigation-off since the early 10-leaf stage to emergenc...

Proline is an important metabolite that plays adaptive role in plants under water-deficit stress. Understanding the genetic basis of water-deficit-induced proline accumulation remains elusive crop plants, especially wheat. Here, we investigated control and conditions using a diversity panel which comprises 150 bread wheat cultivars. Water-deficit stress significantly increased than well-water t...

The water availability at early phenological stages is critical for crop establishment and sugarcane varieties show differential performance under drought. Herein, we evaluated the relative importance of morphological and physiological plasticity of young sugarcane plants grown under water deficit, testing the hypothesis that high phenotypic plasticity is associated with drought tolerance. IACS...

To investigate the lignification process and its physiological significance under drought-stressed conditions, the changes in enzymes responsible for lignification and the related physiological parameters were determined in white clover (Trifolium repens L.) leaves during 28 d of water deficit treatment. Water deficit gradually decreased leaf water potential (Psiw) to -2.33 MPa at day 28. For t...

The present study aimed at the development of the water deficit coefficient as a function of the Christiansen uniformity coefficient and relationship between the applied water depth and that required by a given crop, taking into account that the water distribution by the sprinkler follows a normal distribution. Another objective was to compare the experimental results to those obtained through ...
