Variation and correlation analysis of leaf traits of three Acer species in different growth periods in the Xiaoxing’an Mountains of northeast China
【Objective】 Leaf traits play important roles in plant resource acquisition and photosynthetic capacity. Therefore, plants can adapt to different leaf-growth periods by adjusting their leaf traits. 【Method】Acer ukurunduense, A. tegmentosum and A. pictum subsp. mono, three typical Acer species in the Xiaoxing’an Mountains of northeast China were selected as the objects of the study. During the three growth periods of leaf expansion (early June), leaf stabilization (mid-July), and leaf senescence (early September), the specific leaf area, leaf dry matter content, chlorophyll, and leaf thickness were measured. Additionally, the growth dynamics of the leaf traits and the correlations between traits were analyzed. 【Result】 Significant differences existed in leaf traits among different Acer species in different growth periods, and the leaf thickness in the leaf expansion period and leaf dry matter content in the leaf stabilization period were significantly higher than the other two periods. The correlation between leaf traits varied significantly with different growth periods. Three Acer species exhibited the “quick investment-return” strategy in the leaf expansion period and the “slow investment-return” strategy in the leaf stabilization and leaf senescence periods. Leaf traits and their correlations were significantly different at the species level. 【Conclusion】Plants adapt to different growth periods through leaf trait variations and different combinations of leaf traits, and finally form various survival strategies.
