【目的】研究油橄榄(Olea europaea L.)叶片功能性状特征,筛选出研究区域的优良品种,为四川盆地油橄榄的推广和种植提供科学依据。【方法】以四川盆地相同生境中的9个油橄榄品种为研究对象,对其叶片形态特征、光合特性、光合色素含量及营养元素含量进行分析测定和评价。【结果】9个油橄榄品种间叶片的功能性状表现出了一定的种间差异性,‘阿桑贝拉’(‘Assanbella’)、‘颚植8号’(‘Ezhi-8’)、‘莱星’(‘Leccino’)、‘豆果’(‘Arbequina’)、‘克罗莱卡’(‘Koroneiki’)和‘皮瓜尔’(‘Picual’)叶片的功能性状表现较优,其中‘阿桑贝拉’最优;‘柯拉蒂’(‘Coratina’)、‘小苹果’(‘Manzanillo’)叶片的功能性状表现较差,‘格洛桑’(‘Grossane’)最差。9个油橄榄品种叶片厚度、叶干质量和营养元素含量两两间变化趋势相同,光合特性和光合色素含量变化趋势相同。【结论】9个油橄榄品种在相同生境下叶片功能性状差异较大,表现出不同的适应特性。9个品种中以‘阿桑贝拉’、‘颚植8号’、‘莱星’、‘豆果’、‘克罗莱卡’和‘皮瓜尔’叶片的功能性状表现较优,可在川中盆地地区推广应用。

【Objective】This research aimed to study the functional characteristics of Olea europaea L. leaves, select the dominant varieties in the study area, and provide a scientific basis for the promotion and planting of olives in the Sichuan Basin. 【Method】Nine dominant olive varieties of the Sichuan Basin were selected to evaluate leaf morphological and photosynthetic characteristics, photosynthetic pigment concentrations and nutrient contents. 【Result】The functional traits of leaves of nine olive varieties showed some inter-species differences, and the leaf functional characters had a significant positive effect on ‘Assanbella’, followed by ‘Ezhi-8’, ‘Leccino’, ‘Arbequina’, ‘Koroneiki’ and ‘Picual’, and a negative influence on ‘Coratina’, ‘Manzanillo’ and ‘Grossane’, among which ‘Grossane’ was the worst. The changes in leaf thickness, dry matter and nutrient contents of nine olive varieties were the same, as were the changes in photosynthetic characteristics and pigment contents. 【Conclusion】The nine olive varieties evaluated have different leaf functional characteristics in the same habitat, showing different adaptive plasticity. Among these varieties, ‘Assanbella’, ‘Ezhi-8’, ‘Leccino’, ‘Arbequina’, ‘Koroneiki’ and ‘Picual’ have better functionality, which can facilitate their wide use in the central Sichuan Basin.
