Fertilization and seasonality influence on the photochemical performance of tree legumes in forest plantation for area recovery in the Amazon

Abstract: N-fixing leguminous species can reach atmospheric dinitrogen gas (N2), having an advantage under N-limited degraded environments. These N-fixers are constantly used as facilitative species. Chlorophyll a fluorescence (ChF) acknowledges how different species take up and use light energy during photosynthesis. These techniques assess stress and performance responses to photosynthesis and are used for the selection of species with potential for reforestation. Six Fabaceae species were selected for this study: thr… Show more

“…Their changes during environmental stress can be used to judge the degree of damage to photosynthetic organs and visualize the disturbance in thylakoid membrane caused by stress. 75 , 76 In this experiment, the decrease of F v / F m and PI ABS of OE-10 lines under salt stress was significantly greater than that of Col-0, indicating that MYB72 transcription factor significantly reduced the PSII photochemical activity and NaCl tolerance of A. thaliana . To further analyze the effect of MYB72 on PSII status under salt stress, we standardized the obtained original OJIP curve.…”

“…This can be verified by the greater increase in above-ground biomass, larger leaf area, and greater leaf gain, and this contributes to the carbon gain since it is directly related to the photosynthetic capacity of plants. Plants with larger leaf areas and leaf gains have larger surface areas to capture light and, consequently, a higher biomass content [ 39 ].…”

“…Dry biomass accumulation and growth rates in diameter and height are parameters that have already been applied to several tropical tree species in order to analyze and understand the balance between, and the levels of, nutrients in the soil and in the plant [ 23 , 39 ]. In this context, the plant responses almost always suggest that their physiological performance is limited by P [ 9 , 40 ].…”
