AbstractThis paper deeply explored the effects ofdifferent plant growth regulators on the germination of Hippophae rhamnoides seeds.Four plant growth regulators including gibberellin（ GA3 ），ethephon（ETH）， GGR6 and ABT rooting powder were selected.By measuring the germination rate and germination potential of sea buckthorn seeds，seed quality was evaluated，suitable planting methods were selected，and crop yield and quality were improved.The results showed（ 1）200mg/L gibberellin soaking treatment significantly increased the seed germination rate and germination potential of deep autumn red.The seed germination rate and germination potential of Chinese seabuckthorn were significantly increased by 100mg/L gibberellin soaking treatment.（2）Through the GGR soaking test，it can be speculated that there may be an optimum concentration between 15-30mg/L ，which makes the germination rate and germination potential of the seeds increase；the concentration of 45mg/L GGRsoaking treatment ofChinese sea buckthorn is more suitable concentration.（3）Three test concentrations of ethephondid not promote the germination rate ofthe seeds of red sea buckthorn and Chinese sea buckthorn. （4）The germination rate and germination potential of deep autumn red seeds were significantly improved under 100mg/L ABT soaking treatment. In summary， different varieties of sea buckthorn seed germination.
