تاثیر تیمارهای مختلف دمایی بر جوانه زنی بذر اسپرس کرمانی

In order to evaluate the effect of different temperature treatments on seed germination wild type of Onobrychis Kermanensis an experiment was conducted based on completely randomized design with three replications and eight treatments in the Laboratory of the faculty of agriculture, Shahid Bahonar University of Kerman in 2013. The experimental treatments were (temperature of 5 ° C for seed, - temperature of 5 ° C for pod, - temperature of 25 ° C for seed, - temperature of 25 ° C for pod, - temperature of 50 ° C for seed, - temperature of 50 ° C for pod, - temperature of 5 ° C with seed scarification (50%) for 30 minutes and - temperature of 5 ° C with seed scarification (50%) for 60 minutes). Finally, number of germinated seeds, day to germination and length of radical was estimated. The Analysis of Variance Results showed that the experimental treatments had significant effect on all the traits. The highest number of germinated seed and length of radical was related to temperature of 5 ° C for seed treatment. While, the lowest value of the two traits was gained in temperature of 50 ° C for pod تtreatment. Generally, temperature of 5 ° C for seed treatment with average 6 day length for germination was found the best treatment for dormancy break and stimulating germination of Onobrychis seed.The for domestication of this wild type can be vstel for increasy of drught to kermanensis potential of onobrychis.
