中文摘要	以在安徽省广泛栽培的薄壳山核桃〔Carya illinoinensis(Wangenh.)K.Koch〕品种波尼'(Pawnee')、马罕'(Mahan')和威斯顿'(Western')为研究材料,比较3个品种叶片结构特征和枝条导水功能,并运用隶属函数值法评价其抗旱性。结果显示:总体上看,与马罕'相比,波尼'和威斯顿'的气孔小而密,叶脉密度较高;波尼'和威斯顿'的叶片、上表皮和下表皮较厚,明显厚于马罕';波尼'和威斯顿'的叶片组织结构紧实度和比叶质量显著高于马罕';马罕'导管直径为45.1 mum,显著大于波尼'(42.2 mum),但波尼'和威斯顿'的导管密度和导管壁加固度显著大于马罕';3个薄壳山核桃品种的边材比导率差异不显著,而波尼'和威斯顿'枝条的自然状态下导水损失率分别为23.3%和22.2%,显著低于马罕'(32.9%);波尼'木材密度最大(0.49 g·cm~(-3)),显著高于马罕'(0.45 g·cm~(-3))和威斯顿'(0.45 g·cm~(-3))。隶属函数值法分析结果表明: 波尼'和威斯顿'各指标隶属函数值的均值分别为0.55和0.52,明显大于马罕'(0.44)。综上所述,波尼'和威斯顿'抗旱能力较马罕'更强,适宜在较干旱地区推广种植。
英文摘要	Taking widely cultivated cultivarPawnee',Mahan',andWestern'of Carya illinoinensis(Wangenh.)K.Koch in Anhui Province as research materials,the leaf structure characteristics and branch hydraulic function of the three cultivars were compared,and their drought resistance were evaluated by using subordinate function value method.The results show that compared withMahan',the stomata ofPawnee'andWestern'are small,their stomatal densities are high,and their vein densities are relatively high in general;the leaf,upper epidermis,and lower epidermis ofPawnee'and Western'are relatively thick,and are evidently thicker than those ofMahan';the tightness degree of leaf tissue structure and specific leaf mass ofPawnee'andWestern'are significantly higher than those ofMahan';the vessel diameter of Mahan'is 45.1 mum,and is significantly greater than that of Pawnee'(42.2 mum),but the vessel density and vessel wall reinforcement of Pawnee'and Western'are significantly greater than those of Mahan';the differences among sapwood specific conductivity of the three cultivars are not significant,while the natural percentage loss of hydraulic conductivity of branches ofPawnee'andWestern'are 23.3% and 22.2%,respectively,which are significantly lower than that ofMahan'(32.9%);the wood density ofPawnee'is the largest(0.49 g·cm~(-3)),and is significantly higher than those of Mahan'(0.45 g·cm~(-3))and Western'(0.45 g·cm~(-3)).The subordinate function value method analysis result shows that the subordinate function values ofPawnee'andWestern'are 0.55 and 0.52 respectively,which are evidently higher than that ofMahan'(0.44).In conclusion,the drought resistance ofPawnee'andWestern'are stronger than that ofMahan',therefore,they are suitable for planting in arid areas.
