摘　　要：为探究不同品种藿香种子在萌发与生长上的差异情况,采用随机区组设计,研究15个不同品种的藿香种子萌发状况、主要农艺性状、保护酶活性及相关关系。结果表明,不同品种藿香种子萌发状况存在差异,以H9、H4、H15处理下藿香种子发芽率、发芽势、发芽指数和活力指数相对较高。不同品种藿香种子萌发后在生物量上的表现亦存在不同,以H4、H9、H15处理下藿香发芽数、胚轴长、胚茎粗相对较大,H14处理下发芽数最少,H7处理下胚轴长最短,H14处理下胚茎粗最小。不同品种藿香种子萌发后的SOD、POD、CAT活性存在较大差异,其中以H9、H4处理下的藿香种子SOD、POD、CAT活性相对较高,活性氧清除能力相对较强;H1处理下的藿香种子SOD活性最低,H7处理下的藿香种子POD活性最低,H14处理下的藿香种子CAT活性最低。相关性分析表明,藿香种子发芽数与SOD、POD、CAT具有极显著正相关关系,胚轴长与POD、CAT具有显著正相关关系,胚茎粗与SOD、CAT具有极显著正相关关系。To explore differences in germination and growth of various Agastache rugosa seed varieties,a random block design was utilized to study the germination status,main agronomic traits,protective enzyme activity,and related relationships of 15 varieties of Agastache rugosa seeds.The results showed differences in the germination status among the Agastache rugosa seeds,with the germination rate,germination potential,germination index,and vitality index being relatively high under H9,H4 and H15 treatments.The biomass performance of Agastache rugosa seeds varied among the different varieties after germination,with the germination number,hypocotyl length,and embryonic stem thickness being relatively larger under H4,H9 and H15 treatments.The germination number was the lowest under H14 treatment,the hypocotyl length was shortest under H7 treatment,and the embryonic stem thickness was smallest under H14 treatment.There were significant differences in the SOD,POD and CAT activities of Agastache rugosa seeds among the different varieties after germination.Among them,the SOD,POD and CAT activities of Agastache rugosa seeds treated with H9 and H4 were relatively high,and the ability to scavenge reactive oxygen species was relatively strong.The SOD activity was the lowest under H1 treatment,the POD activity was the lowest under H7 treatment,and the CAT activity was the lowest under H14 treatment.Correlation analysis showed a highly significant positive correlation between the germination number of Agastache rugosa seeds and SOD,POD and CAT and a significant positive correlation between embryonic axis length and POD,CAT and a highly significant positive correlation between embryonic stem diameter and SOD,CAT.
