Effects of Seed Scarification on Seed Germination and Early Growth of Olive Seedlings

A.A. Rostami and A. Shasavar

Abstract:
Present study conducted to evaluate the effects of chemical and mechanical scarification treatments on percentage and rate of seed germination of olive cultivars (Arbequina and Koronaiki). Results indicated that chemical and mechanical scarification treatments followed by an adequate stratification period can increase seed germination significantly. The best results obtained by chemical scarification treatments and mechanical scarification were not as effective. Chemical scarification treatments removed seed surrounding structure more uniform. The least germination rate and percentage was observed in control treatments. The highest germination percentage of cv. Koronaiki obtained after 97% sulfuric acid solution treatments for 6 h (up to 73%). Treating seeds of this cultivar by 97% sulfuric acid for longer period resulted in damage to embryo and no seedlings emerged after these treatments. The best result for cv. Arbequina observed following 97% sulfuric acid treatment for 9 h (69.5%). Mechanical treatment had no effect on germination percentage or germination rate of seeds of this cultivar. Growth of olive seedlings also increased by scarification treatments significantly. Results suggested that chemical and mechanical scarification treatments can improve germination percentage and seedling growth of olive cultivars.
