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。
In order to clarify the distribution of wild peach (Prunus persica (L.) Batsch) in Wuyishan area of China, the wild peach resources in Zhejiang, Jiangxi and Fujian Wuyi mountain ranges were systematically investigated, collected and evaluated. The study collected a total of 244 wild peach resources, from Wuyishan area 24 collection points. Phenology evaluation found that these resources are rich in polymorphism. Correlation analysis showed that there was a significant and positive correlation between leaf sprouting and flowering and altitude and latitude of collecting point. Fruit evaluation showed that fruit traits were rich in polymorphism. Through 2 years of waterlogging resistance evaluation, 53 strains of wild progeny of wild peach were screened out. Correlation analysis of net photosynthetic rate, stomatal conductance, transpiration rate and flooding time showed that flooding time had a significantly negative correlation with net photosynthesis rate, stomatal conductance and transpiration rate, but net photosynthetic rate, stomatal conductance, transpiration rate The three were extremely significant positive correlation.
