STAY GREEN: A BETTER SUBVENTION FOR CROP IMPROVEMENT. Stay Green

      Аннотация: Stay green is general term given to a variant in which senescence is delayed compared with standard reference genotype. The ability of a plant to postpone/delayed senescence and retain their leaves in the active photosynthetic state. Therefore, expected to give a higher production and productivity of grain as well biomass under biotic and abiotic stress condition. The extended foliar greenness during grain filling delayed senescence and maintain more photo synthetically active leaves . Genetic variation exists in the timing and rate of leaf senescence, both between species and genotypes. Furthermore, mutants also occur whose leaves remain green for longer than those of the parental genotype.
