干旱胁迫影响下的植物个体响应与种间关系变化
Individual Plant Response and Interspecific Relationship Changes Under Drought Stress:Exemplified by Parasitic Plants
摘要
Abstract
As the water cycle and rainfall patterns have been affected by the continuing global warming,the frequent drought events will become a major stress challenging plant communities.Drought-induced water scarcity severely affects plant growth and development,and can easily cause individual plant decline or even death.In-depth analysis of the consequences of drought impacts and the response mechanisms of plants is a key scientific issue for understanding and predicting changes in different plant groups.Parasitic plants are special groups that use their haustorium to extract water and nutrients from host plants.Due to the formation of a physically connected system,drought stress can trigger individual regulatory responses and change interspecific interactions between the parasitic and host plants.Therefor,it is worthwhile to further explore the specific processes and physiological significance.Additionally,parasitic plant groups include both the species that are harmful to agricultural and forestry production and the species that have excellent utilization value,so the study of the drought response of this group is conducive to targeted their control or cultivation.This paper mainly introduces the effects of drought stress on the hydrological and photosynthetic systems,physiological and biochemical processes,morphology and structure of individual plants and their response strategies,and also examines the different regulation mechanisms against drought stress by the facilitative and competitive effects in interspecific interactions of plants.The focus is put on the changes in parasitism relationship under drought stress,including the amplification of the negative effects of drought stress and the improvement of the host condition under drought stress.This paper intends to provide a reference for deepening the study of physiological processes and interspecific relationships of parasitic plants under drought impacts.关键词
