بررسی پیش تیمار بذر بر شاخص‌های جوانه‌زنی بذر ماریتیغال (خار مریم) تحت شرایط تنش شوری

 Improvement of seed priming techniques that can increase the speed and percentage of germination, emergence and germination increased range of environmental stress such as salinity, temperature, and drought. In order for this test to assess the effect of priming on seed germination of Silybum marianum salinity in completely randomized design with 3 replications. Treatments consisted of five levels of salinity (zero as a control, 2, 4, 8 and 12 dS.m-1) and three levels of priming (GA3, SA and KNO3) were. The effect of salinity the showed a variance significant on seed germination percentage and seedling abnormalities and normal, and the priming on germination percentage, mean germination time, germination and seedling number of normal and non-normal, root, shoot and total dry weight. With increasing salinity levels decreased significantly in percentage, speed of germination and mean germination time. Pre-treatment of SA and GA3 seed with KNO3 towards a better effect on germination percentage, mean germination time and germination of variance. Germination pretreated with KNO3 77.51 percent respectively, almost twice the pre-treatment with other drugs. General, can be used as a mitigating material (KNO3) and percentage of seed germination in Silybum marianum saline condition improved.
