Effects of drought hardening on the carbohydrate dynamics of Quercus acutissima seedlings under successional drought

Qiang Li, Xiao Liu, Xinke Sun, Mingming Zhao et autres

Introduction As precipitation patterns are predicted to become increasingly erratic, the functional maintenance of warm-temperate forests constitutes a key challenge for forest managers. In this study, 2-year-old Quercus acutissima seedlings were selected to elucidate the mechanisms whereby they respond to soil water …

Response mechanisms of 3 typical plants nitrogen and phosphorus nutrient cycling to nitrogen deposition in temperate meadow grasslands

Yang Zhang, Qing Zhang, Wenjun Yang, Yan Zhang et autres

The increase of nitrogen (N) deposition and the diversity of its components lead to significant changes in the structure and function of temperate meadow steppe, which could affect plant nutrient uptake, nutrient resorption and litter decomposition, thus affecting the biogeochemical cycle process. …

Physiological Responses of Robinia pseudoacacia and Quercus acutissima Seedlings to Repeated Drought-Rewatering Under Different Planting Methods

Xiao Liu, Qinyuan Zhang, Meixia Song, Ning Wang et autres

Changing precipitation patterns have aggravated the existing uneven water distribution, leading to the alternation of drought and rewatering. Based on this variation, we studied species, namely,Robinia pseudoacaciaandQuercus acutissima, with different root forms and water regulation strategy to determine physiological responses to repeated …

Plant Size Plays an Important Role in Plant Responses to Low Water Availability and Defoliation in Two Woody Leguminosae Species

Ning Wang, Qiang Li, Xiao Liu, Shijie Yi et autres

Plant size influences plant responses to combined environmental factors under climate change. However, their roles in plant ecophysiological responses are not fully understood. Two rapidly growing Leguminosae species (Robinia pseudoacacia and Amorpha fruticosa) were used to examine plant responses to combined drought …

Effects of defoliation modalities on plant growth, leaf traits, and carbohydrate allocation in Amorpha fruticosa L. and Robinia pseudoacacia L. seedlings

Ning Wang, Mingming Zhao, Qiang Li, Xiao Liu et autres

Defoliation modality significantly affected leaf traits and carbon allocation especially in the early recovery period of two Leguminosae woody species . Robinia pseudoacacia L. recovered more quickly following defoliation than Amorpha fruticosa L. Defoliation resulting from anthropogenic disturbance, insects, and grazing animals …
