摘　　要：为了评价和比较云贵高原地区不同葡萄种质资源叶片的耐霜冻能力,为野生葡萄资源开发与利用提供依据,本试验对6种野生葡萄资源以及1种栽培品种的嫩叶进行了人工霜冻处理,建立嫩叶的冻害比例与低温关系的Logistics模型,获得反映叶片耐霜冻能力的3个参数LT10、LT50和LT90,并将其用于不同种质资源耐霜冻能力的比较。结果发现,云贵高原地区葡萄种质资源的霜冻敏感范围为﹣6.48~﹣2.26 ℃;在参试资源中,最耐霜冻的是刺葡萄,最不耐霜冻的是网脉葡萄。综上所述,云贵高原地区7种葡萄种质资源的抗霜冻能力较强,其对霜冻低温的适应范围较宽,这些特性均有利于其在恶劣的突发性降温天气中存活,具有较高的开发利用价值。In order to evaluate and compare the frost resistance in leaves of different grapevine germplasm resources in the Yun-Gui plateau,and to provide a basis for the development and utilization of wild resources,artificial frost treatments were conducted in leaves of six wild grapevine germplasm resources and one cultivar.A Logistics model was used to establish the relationship between the freezing damage ratio and low temperature.LT10,LT50 and LT90 were calculated from Logistics model when the injury ratio were 10%,50% and 90% to reflect the differences in frost sensitivity of leaves.It was found that,the sensitive temperature range that grapevine germplasm resources leaves to frost was from ﹣6.48 ℃ to ﹣2.26 ℃ in Yun-Gui plateau.The most frost-tolerant was V.bellula (Rehd.) W.T.Wang,the most frost-sensitive was V.wilsonae Veitch..Therefore,seven grape germplasm resources in the Yun-Gui plateau have strong frost resistance and a wide range of adaptation to frost and low temperature,which are conducive to their survival in harsh cooling temperatures.These germplasm resources are of high value in development and utilization.
