Genetic variation of leaf pigment content in a southern beech

Leaf Traits Explain the Growth Variation and Nitrogen Response of Eucalyptus urophylla × Eucalyptus grandis and Dalbergia odorifera in Mixed Culture

“…A reason for this finding is that the significant reduction in nonstomatal factors such as WUE and CE in D. odorifera leaves grown in mixed cultivation limits the photosynthetic response process [63]. Moreover, the significant decrease in chlorophyll and carotenoid contents in D. odorifera plants grown in a mixed cultivation system reduced the light capture and photoprotective capacity of the leaves [43]. The combined effects of mixed culture and N application increased the water and nutrient competitive ability of E. urophylla × E. grandis and decreased that of D. odorifera, which resulted in the overall improvement and decline of the leaf photosynthetic physiological functions of E. urophylla × E. grandis and D. odorifera, respectively [64,65].…”

“…Based on this information, this study used controlled pot experiments of Eucalyptus urophylla × eucalyptus grandis (E. urophylla × E. grandis) and Dalbergia odorifera (D. odorifera) to investigate the effects of mixed cultivation, N addition, and co-treatments on leaf functional traits as well as further on the growth and biomass of seedlings. In this study, leaf morphological/structural, physiological, and chemical traits related to plant growth and development were collected according to previous methods (Table S1) [39][40][41][42][43][44][45][46]. The objectives of this research were (1) to understand the adaptive mechanisms of leaf traits in E. urophylla × E. grandis and D. odorifera in response to mixed cultivation and N application, (2) to test the hypothesis that mixed plantation and N application and their cotreatments promote the growth and development of E. urophylla × E. grandis and D. odorifera, and (3) to elucidate the correlation between key leaf traits and the growth of E. urophylla × E. grandis and D. odorifera, as well as their respective regulatory pathways.…”
