Abstract

The extreme weather conditions of Transbaikalia cause phytostress in plants. This results in the formation of protective systems and mobilization that involves certain metabolic changes acting as survival means, including an increase in the content of lipids and lignin. Metabolism undergoes modifications determined by the pace and depth of changes that can occur in it without disturbing the balance between individual functions; as a result, the unity of the plant and the environment is not disturbed. Cryoarid conditions cause specific morphological and chemical adaptations in plants. It was found that the total content of lipids and lignin in the studied soils of Transbaikalia is higher, while the content of proteins is lower compared to similar soils in European Russia. It was also established that virgin chestnut soils contain more lipids, lignin, and proteins compared to fallow and arable soils.

低温土壤的植被：生产力和物种、元素和生化成分

摘要

外贝加尔地区的极端天气条件会对植物造成植物胁迫。这导致保护系统和动员的形成，涉及作为生存手段的某些代谢变化，包括脂质和木质素含量的增加。新陈代谢会发生变化，变化的速度和深度决定了新陈代谢的变化，而不会影响个体功能之间的平衡；因此，植物与环境的统一不会受到干扰。低温条件会导致植物发生特定的形态和化学适应。研究发现，与俄罗斯欧洲部分的类似土壤相比，外贝加尔地区的土壤中脂质和木质素的总含量较高，而蛋白质含量较低。研究还发现，与休耕和耕地土壤相比，原始板栗土壤含有更多的脂质、木质素和蛋白质。
