    Abstract:

    Abstract: In order to confirm the wild peach resources status in Wuyi mountains, the wild peach resources were systematic investigated, collected and evaluated. We collected 244 wild peach resources which come from 24 collected points in this survey. Wild peach resources were found mostly in mountain area. Average altitude of collection point is 522.47m. Wild peach resources in Zhejiang and Fujian province, mostly are at higher altitudes. We found these wild peach resources with plentiful variety 18 short chilling requirement wild peach resources by phenology evaluation, . Correlation analysis showed that the period of buds germination, Stage of initial bloom and collection point altitude and latitude was a highly significant positive correlation. Fruit evaluation shows plentiful variety infruit traits. one of these resources leaves buds germinate before all leaves fall. W e also found 2 red-fleshed and a flat wild peach resources. By two years of water logging evaluation, we selected 53 individuals of wild peach resourceses progeny with Water logging tolerance partly. The photosynthetic rate, stomatal conductance, transpirational rate and the flooded days correlation analysis shows that the flooded days was highly significant negative correlation with the photosynthetic rate, stomatal conductance and transpirational rate, the photosynthetic rate, stomatal conductance, transpirational rate was a significant positive correlation each other.Suggestions related to their protection were put forward in order to insure the sustainable use.
