Abstract
Study was conducted to determine the effects of osmo-priming on germination of pea seeds (Pisum sativum L). Experiment was arranged under completely randomized design (CRD) with three replicates. This study was conducted in germination cabinet at Gaziantep University Vocational School of Higher Education in Nurdagi during February-May 2013. Seeds were primed in various osmotic potential of polyethylene glycol-6000 (-0.3, -0.6, -0.9 and -1.2 MPa) and distilled water (2.5 μs/cm) at 20 0C for 24 hours and there was also a control treatment. In this study, 3 pea cultivars (Utrillo, Carina and Rondo) were used and germination tests were carried out in dark conditions in a germination cabinet held at 20 0C and 50% relative humidity for 8 days. The beneficial and harmful effects of priming depend on the organism physiology and aim of this study Hydro and Osmo-Priming effects on germination in pea (Pisum sativum L.) seeds. Seedling length, germination percentage, vigor index values varied between treatments 1.32-5.85cm, 48.33-86.39% and 73.54-543.89, respectively. Results showed that Carina cultivar is more resistant to osmotic stress than other pea cultivars (Rondo and Utrillo).
