ارزیابی شرایط انبارداری بر خصوصیات جوانه‌زنی بذر گلرنگ در شرایط آزمایشگاه

In order to evaluation of the effects of Storage duration on safflower germination traits, an experiment was laid out as a factorial based on Completely Random Design with three replication in the laboratory and greenhouse of Seed and Plant Certification and Registration Institute (SPCRI)in Karaj in 211. The experiment factors including infected and non-infected Safflower’s seeds with teliospors of rust and seed treatment by Carbendazim, Carboxin thiram and Tebuoconazol, and without dressing (control), storability time for zero,45,90 and 180 days after treatment. The analyzed factors in laboratory conditions including: final germination and normal seedling percentage, germination speed, length of seedling, seedling vigor of longitudinal and weighty index, seedling dry mean time of germination in lab, also mean time seedling emergence, field emergence rate, cumulative emergence rate, seedling vigour index, seedling dry weight and measuring leaf surface in green house. Based on the results it was noticed that storing seed for 180 days has decreased normal seedling percentage about 14% compared to without storing. It was seen that, normal seedling percentage in no infected seeds treated by Tebuoconazol was 36% higher in comparison infected seeds treated by Carbendazim. Germination speed in non-infected seed without dressing was 38% higher than infected seeds treated by Carbendazim.
