Role of Root Traits and Root Phenotyping in Drought Tolerance

The spatial distribution of all root parts in a particular growth environment is collectively referred to as system architecture (RSA). Root length, cortical cell file number, number roots and size help determining water uptake ability among various types an adaptation strategy under dry conditions. Using combination phenotyping techniques that include laboratory, greenhouse, field evaluations, characteristics can be identified selected. Roots play significant role the plant's capacity recover from drought stress. attributes are influenced by environmental factors, difficult measure field, regulated polygenes. Different properties, including angle, surface area, have quantitative trait loci been found. Crop yield efficiency with which nutrients used could both improved genetically improving drought-prone areas. alleles may introduced into elite cultivars create desired phenotypes through molecular breeding order ensure crop productivity harsh environment.
