The Effect of Priming with Potassium Nitrate on Borago officinalis under Salinity Stress Mahtab salehi* Horticultural Sciences and Engineering Department, University of Nahavand Email: mhtb.salehi@gmail.com The beneficial effects of priming are not exclusive of seed germination and can be extended to later stages by increasing tolerance to different biotic and abiotic stresses [1]. In order to study the effect of KNO3 on germination of Borago officinalis under salinity stress, this study was done as a factorial experiment using a completely randomized design with 5 levels of salinity (0, 2, 4, 6, 8 dS/m) and 3 levels of KNO3 (0, 0.03, 0.5%) with 3 replications. The results showed that salinity had significant effect on germination percentage, stem length and fresh weight. The priming effect on germination percentage, stem length and fresh weight was significant. The most germination percentage, stem length and fresh weight were obtained with using KNO3 in level of 5%.
