- 摘要:
- 以从日本引进在大连地区栽植的越橘属7个蓝莓品种为试材，研究了不同类型蓝莓种子的形态及其萌发特性，以期为辽宁南部地区蓝莓的引种栽培、新品种选育提供科学依据。结果表明：蓝莓品种之间种子形态特征和萌芽特性均存在显著差异。半高丛蓝莓“北空”的种子千粒重最大，南高丛蓝莓最小；南高丛蓝莓“奥尼尔”种子长度明显高于其余品种；南高丛蓝莓种子萌发率明显高于其余类型，“布里吉塔”和“芝妮”种子萌发率最低；蓝莓的发芽速度很慢，平均发芽时间为30 d左右。相关分析表明，蓝莓种子大小对萌发的影响并不显著。
- Abstract:
- Taking seven Vaccinium L. cultivars that introduced from Japan to Dalian as materials，seed morphology and germination characteristics of different Vaccinium L. cultivars were analyzed，in order to provide cultivation technology and scientific basis for breeding new varieties to southern Liaoning.The results showed that there were significant differences in seed morphologygermination characteristics.The 1000-seed weight of half-high bush blueberry cultivar ‘Northsky’ was the highest，while that of southern high bush blueberry was the lowest.The seed length of southern high bush blueberry ‘ONeal’ were significantly greater than those of other varieties，and the germination rate of southern high bush blueberry were significantly greater than those of other cultivars，while the germination rate of ‘Brigitta’ and ‘Chignecto’ was the lowest.The germination speed of blueberry was slow，mean germination time was around 30 d.Correlation analysis2showed that there was no significant correlation between seed size and germination.
