Abstract

Abstract:

【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.

Key words: Olea europaea L., variety, leaf morphological characteristics, photosynthetic characteristics, chlorophyll content, nutrient elements
