The Effects of Silicon Dioxide Priming on Some Germination and Vegetative Growth Parameters of Rocket Cultivars Under Salt Stress Conditions

Rocket (Eruca vesicaria), a plant from the cruciferous (Brassicaceae) family, whose leaves are eaten as salad, is also considered medicinal due to its different therapeutic properties. In this study, effects of silicon dioxide priming (0.5, 1, 1.5 mM SiO2) on germination and vegetative growth properties two rocket cultivars (Geniş Yaprak, Eda) were investigated under increased salt stress conditions (150, 200 NaCl). For purpose, percentage (GP), index (GI), rate coefficient (CVG), mean time (MGT) (GRI) calculated parameters. Shoot root length (mm), leaf width fresh weight (g) measured in seedlings developed germinated seeds, seedling vigour (SVI) was calculated. The SiO2 differed according cultivar. Geniş Yaprak cv., 1 application had positive effect parameters both seeds not applied 150 stress, 30% 73%, especially salty conditions. Under same Although applications Eda cv. effective stress-free conditions, they Especially, dose SVI, shoot weight. concentrations, made slight improvement such leaves, roots shoots determined at doses for concentrations.
