大兴安岭南段蒙古栎粗根非结构性碳对不同坡向的响应

doi:10.13866/j.azr.2024.09.13

Abstract

Abstract:

The distribution of carbon within plant aboveground and subsurface organs is important for understanding the carbon storage systems in tree roots in semi-arid areas. In this study, coarse root samples of Quercus mongolica. were collected monthly during the growing seasons of 2021 (wet year), 2022 (dry year), and 2023 (normal year). The changes in nonstructural carbon and its components (soluble sugar and starch) were analyzed; the NSC (Non-Structural Carbohydrate) content of coarse root was primarily starch, and it increased significantly with seasonal changes (P<0.05). The NSC and starch contents were highest during the wet season, followed by the normal and dry seasons. The starch content was highest on the sunny slope, followed by the semi-sunny and shady slopes regions (P<0.05). Slope characteristics affect the NSC and component contents of coarse roots, as NSC and component contents change in response to potential evapotranspiration gradients. The findings provide a better understanding of the mechanisms controlling carbon distribution within plant underground organs in response to arid conditions.
