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.
