Spatial Patterns of Non-Structural Carbohydrates in Eucalyptus urophylla× E. grandis under Dry-Season Irrigation with Fertilization

Non-structural carbohydrates (NSC) affect tree growth and survival when photosynthesis is impacted by climate change, such as seasonal drought extreme precipitation. Nevertheless, it still unclear whether Eucalyptus suffers limitation under natural conditions if trees recover artificial cultivation. In present study, we conducted a field control experiment to compare the NSC storage in urophylla × grandis on fertilization dry-season irrigation determine variations of stress. The results indicated total soluble sugar (TSS) was primary existing form NSC. spatial patterns, concentration showed gradient differences from source organ sink organ, finally accumulated root. TSS decreased trend with height except leaf, while starch contrast. Surprisingly, had not changed carbon distribution among all tissues but reduced most organs. fast-growing E. will consume assimilates organs, maintains at certain threshold. Our help comprehend allocation improve productivity plantations arid areas.
