摘　　要：为了筛选出能够促进突尼斯软籽石榴种子萌发的植物生长调节剂及其适宜浓度,采用不同浓度的赤霉素(GA_(3))、萘乙酸(NAA)、吲哚丁酸(IBA)、6-苄氨基腺嘌呤(6-BA)水溶液对突尼斯软籽石榴种子进行浸泡,测定种子的萌发时间、发芽势、发芽率和发芽指数等4项萌发指标。结果表明:与对照相比,GA_(3)和NAA能显著提高突尼斯软籽石榴种子的发芽势、发芽率和发芽指数,对萌发时间的影响不显著;IBA延长突尼斯软籽石榴种子萌发时间,但差异不显著;6-BA显著延长突尼斯软籽石榴种子萌发时间,IBA和6-BA能显著降低突尼斯软籽石榴种子发芽势、发芽率和发芽指数。GA_(3)和NAA对突尼斯软籽石榴种子萌发具有显著促进作用,其中800 mg/L GA_(3)和60 mg/L NAA促进作用最强。In order to screen exogenous hormones that can promote the germination of‘Tunisia soft-seed’pomegranate seeds and their appropriate concentrations,‘Tunisia soft-seed’pomegranate seeds were soaked with different concentrations of gibberellin (GA_(3)),naphthalene acetic acid (NAA),indole butyric acid (IBA) and6-benzylamino-adenine (6-BA).The germination time,germination potential,germination rate and germination index were measured under each treatment condition.The results showed that:compared with CK,GA_(3) and NAA significantly improved the germination potential,germination rate and germination index of‘Tunisia soft-seed’pomegranate seeds,but had no significant effect on germination time.IBA prolonged the germination time of‘Tunisia soft-seed’pomegranate seeds,but the difference was not significant.6-BA significantly prolonged the germination time of‘Tunisia soft-seed’pomegranate seeds.IBA and 6-BA could significantly reduce the germination potential,germination rate and germination index of‘Tunisia soft-seed’pomegranate seeds.GA_(3) and NAA can significantly promote the germination of‘Tunisia soft-seed’pomegranate seeds,among which 800 mg/L GA_(3) and 60 mg/L NAA have the strongest promoting effects.
