Abstract

Abstract: In order to promote blueberry seeds germination to solve the problem of low blueberry seeds germination percentage of hybrid breeding, this study used ‘Chile TKA’ Blueberry varieties as materials. They were treated by scalpel, grind, soak, dense sulfuric acid and sodium hydroxide solution before sowing to analyze potential, germination percentage, germination index, vigor index and seedling fresh weight. The results showed that different ways of pretreatment could improve the germination potential of seeds. Carving, soaking and acid pretreatment can significantly improve the blueberry seeds germination index, vigor index and seedling fresh weight. Scalpel processing seeding fresh weight was 3 times of the control group; germination index was 11.6 times of the the control group; germination index was 3.9 times of the control group; seed germination percentage was 1.8 times of the control group; seed germination potential was 1.5 times of the control group. Carving can be used as the pretreatment of the Blueberry seeds when making a small amount of sowing.

Key words: blueberry, seed, germination, feature, pretreatment
