PEG-mediated osmotic stress induces premature differentiation of the root apical meristem and outgrowth of lateral roots in wheat
Water stress is one of the major environmental stresses causing growth retardation and yield loss of plants. In the past decades, osmotic adjustment, antioxidant protection, and stomatal movement have been extensively studied, but much less attention has been paid to the study of root system reprogramming to maximize water absorption and survival under water stress. Here, it is shown that polye...
متن کاملPolyethylene Glycol (PEG)-Treated Hydroponic Culture Reduces Length and Diameter of Root Hairs of Wheat Varieties
Wheat is an important cereal crop worldwide that often suffers from moisture deficits at the reproductive stage. Polyethylene glycol (PEG)-treated hydroponic conditions create negative osmotic potential which is compared with moisture deficit stress. An experiment was conducted in a growth chamber to study the effects of PEG on root hair morphology and associated traits of wheat varieties. Plan...
متن کاملResponses of Almond Genotypes to Osmotic Stress Induced In Vitro
Drought is one of the major limitations to crop production worldwide. This study was conducted to evaluate the response of five almond genotypes and peach×almond hybrid GF to drought stress in vitro, and screening drought tolerance. Explants subjected to polyethylene glycol osmotic stress ( , , and . % WV) on the MS medium. Increasing PEG level in the medium significantly reduced fresh weight a...
متن کاملVariability of Root Traits in Spring Wheat Germplasm
Root traits influence the amount of water and nutrient absorption, and are important for maintaining crop yield under drought conditions. The objectives of this research were to characterize variability of root traits among spring wheat genotypes and determine whether root traits are related to shoot traits (plant height, tiller number per plant, shoot dry weight, and coleoptile length), region...
متن کاملOxidative stress responses and root lignification induced by Fe deficiency conditions in pear and quince genotypes.
We analysed Pyrus communis cv. Conference and Cydonia oblonga BA29, differently tolerant to lime-induced chlorosis, to identify the key mechanisms involved in their different performance under Fe deficiency induced by the absence of Fe (-Fe) or by the presence of bicarbonate (+FeBic). Under our experimental conditions, a decrease in root elongation was observed in BA29 under bicarbonate supply....
