- 摘要:
- 以新疆木垒县筛选出的早花和晚花2类文冠果优良高产类群为试材，于2008～2010年系统观测了这2类文冠果类群的物候期和种籽产量，分析2008～2010年新疆北疆遭遇春季低温冻害天气对早花和晚花2类文冠果类群结实率的影响，筛选出能抵御春季低温冻害的文冠果高产类群。结果表明：同一文冠果类群不同年份的物候因春季低温冻害的影响而明显推后；2类文冠果类群的盛花期存在明显差异，早花文冠果类群比晚花文冠类群盛花期要早8～14 d；2008～2010年春季低温冻害天气对晚花文冠果类群的产量影响幅度要低于早花文冠果类群，对早花文冠果类群的种籽产量影响很大，减产或绝收。晚花文冠果高产类群在抵御春季低温冻害和保持高产方面具有重要的应用价值。
- Abstract:
- Screened out two high yield groups, early-flowering and late-flowering as the material for this study, and systematically observed phenological phase and output of these two groups from 2008 to 2010, the influence to setting percentage for frozen injury in spring between early-flowering and late-flowering in north of Xinjiang was analysed. Breed which could against the low temperature cold injury in spring were selected. The results showed that phenological phase of same group of Xanthoceras sorbifolia in different years was significantly late for the reason of frozen injury in spring; Full-bloom stage were great differences between these two groups, early-flowering group was earlier 8～14 days than late-flowering; The influence of frozen injury in spring (years of 2008 and 2010) to late-flowering group was lower than early-flowering group, it could cause reduction of output or wipe out to early-flowering group. Late-flowering group of 〖JP5〗Xanthoceras sorbifolia had important application value for resistance to frozen injury in spring and maintaining highly-yielded.
