Abstract

Abstract: In order to explore the best storage condition of Amomum longiligulare T. L. Wu seeds, the effects of sand grind, gibberellic acid (GA₃) treatment, storage condition and storage time on seed germination rate of A. Longiligulare were studied. A. Longiligulare seeds which were harvested at the same year were treated by sand grind and GA₃ soaking, and stored under different conditions. Germination experiments of A. Longiligulare seeds were carried out, and the germination rates were investigated. The results showed that sand grind could not significantly improve the seed germination rate of A. Longiligulare, but could accelerate GA₃into the inside of the seeds. GA₃ had concentration effect on seed germination rate of A. Longiligulare. The best germination rate was obtained by the treatment with 80 μmol/L GA₃ for 8 h. The higher concentration of GA₃ showed inhibitory effect. Room temperature storage was the best storage condition, it was conducive to the post-harvest ripening of A. Longiligulare seeds. The highest germination rate of seeds stored in room temperature was up to (97.78±3.84)%, but the storage time could not be more than eight months preferably. The best storage condition of A. Longiligulare seeds was obtained to lay a solid foundation for promoting the sowing and seedling technology of A. Longiligulare.
