Morpho-Physiology of Mulberry (Morus sp.) Plant on Salinity Stress Tolerance

The accession of mulberry (Morus sp.) with salinity tolerance unavailable in Indonesia is needed to overcome the problem marginal land, especially saline areas country. Therefore, this research aims determine from 6 origins based on growth and physiological parameters. method used was a factorial randomized block design first treatment stem cutting-derived being M1, M2, M3, M4, M5, M6, M7, while second concentration NaCl at 0 mM, 40 60 80 mM. results showed that M2 Bogor categorized as high salt stress, M1 classified sensitive accession. Increasing causes decrease It also decreased parameters such leaf media relative water content increasing dissolved sugars. Genotypic scores indicate potential number leaves, Na+ necrosis percentage sodium toxicity leaf. genotypic score, Na+/K+ ratio, are best select identify stress tolerance.
