Elements distribution (K, Na & Cl) in some grapevine genotypes (Vitis vinifera L.) under salt stress
Abstract:
Salinity, as an abiotic stress, causes significant losses in horticultural production. Future of grape production, as one of the most important economical horticultural fruits, depends on breeding programs and using salt tolerant rootstocks. The aim of this study was to investigate the salinity tolerance and the distribution of ions associated with salinity in six genotypes and Varieties of grapes (Vitis vinifera L.), namely ‘Shahrudi’, ‘Fakhri Sefid’, ‘Sabz Angur’, ‘Divaneh Kashmar’, SH068 and GT01. The factorial experiment based on Completely Randomized design was carried out with two factors of variety and salinity in three replications. Plants were treated with different salinity levels of less than 2 (1.8-1.9), 4 and 6 dS/m for 40 days. Results showed that increasing the amount of sodium chloride in all genotypes, increased sodium and chloride levels in various organs and Potassium in shoot, while it decreased Potassium concentration in roots, significantly (P
