中国武夷山脉地区野生毛桃资源收集与初步评价

为明确中国武夷山脉地区野生毛桃(Prunus persica(L.) Batsch)资源分布现状,对浙江、江西、福建武夷山脉地区野生毛桃资源进行了系统的考察、收集和评价。此次考察共收集野生毛桃资源244份,来自于武夷山脉地区24个采集点。物候期评价发现这些资源多态性丰富。相关性分析显示,叶芽萌动期、花期与采集点海拔、纬度呈极显著正相关。果实评价显示果实性状多态性丰富。通过2年抗涝性评价,初步筛选出53株较抗涝野生毛桃资源后代单株。净光合速率、气孔导度、蒸腾速率与淹水时间相关性分析显示淹水时间与净光合速率、气孔导度、蒸腾速率均呈极显著负相关,而净光合速率、气孔导度、蒸腾速率三者之间呈极显著正相关关系。

Wild peach resources collection and elementary evaluation in Wuyi mountains China

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.
