Morphological, biochemical and genetic variation of rice (Oryza sativa L.) genotypes to vegetative stage salinity stress

Salinity is one of the most serious issues in rice cultivation and production. Salt stress significantly reduced seedling growth performance of rice. This research was conducted to study the effects of vegetative stage salinity stress on morphological, biochemical, molecular and genetic variation of...
