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.

中国沙棘是沙棘属中的一个亚种，果实较小，但产量高，是防风固沙、保持水土的优良树种[1]。作为我国本土沙棘亚种在一定程度上代表了沙棘在本土环境中的自然状态，通过将深秋红沙棘与中国沙棘对比，可以清晰地观察到生长激素对深秋红沙棘种子萌发产生的特殊影响，从而更好地评估其在本土生态环境中的应用潜力。

深秋红沙棘（Hippophae rhamnoides'Shenqiuhong）是以俄罗斯无名引种材料选育出的品种，具有晚熟高产、抗逆性好、适宜冻果采收等特点，是省唯一大面积推广栽植的品种。但近年来，因为树势弱、抗病性差，以及气候条件变化使省冬季低温期推迟等原因，致使冬季采收前果实于枝条上腐败变质，冻果品质下降，导致果实出口量和单价降低[2-3]。在特殊立地条件下，沙棘种子需要高萌发率和快速萌发能力。植物生长调节剂能影响种子萌发，本研究通过筛选合适的植物生长激素，并探究其最佳使用浓度、处理时间等条件来促进沙棘种子萌发，旨在助力沙棘产业发展。

1材料与方法

1. 1 试验材料

供试品种为深秋红和中国沙棘，购买自种子店。植物生长调节剂为赤霉素（GA）GGR6、乙烯利（ETH）、ABT生根粉，均购买自上海伊卡生物。

1.2 试验方法

挑选子粒饱满、优质、无病害沙棘种子为材料，用 0.3% 的高锰酸钾消毒 30min ，蒸馏水冲洗3次，用常温、 60‰ 蒸馏水分别对中国沙棘种子和深秋红种子进行浸泡处理，探究打破休眠的适宜温度，缩短萌发时间的作用，根据种子浸泡状态或种皮特性，选择浸种时间 24-48h ，自然冷却[4-6]。……
