Abstract
Aims
To explore whether grazing-induced legacy effects on plants could benefit plants adaptation to drought.Methods
A water-controlled experiment was conducted in the greenhouse, which with Agropyron cristatum and Carex korshinskyi collected from free-grazing and enclosed plots on a typical grassland in Inner Mongolia.Important Findings
We found that A. cristatum and C. korshinskyi collected from the free-grazing plot were less affected by drought in terms of ramet biomass, ramet number and total biomass than those collected from the enclosed plot. The enhanced adaptation to drought for plants collected from the free-grazing plot should partly be ascribed to the larger root biomass allocation plasticity under drought treatment. Our findings suggest that grazing management can be used to improve the adaptation of grassland plants to climate change.

摘要
目标
探讨放牧对植物的遗留效应是否有利于植物适应干旱。方法
在温室内进行了控水试验,利用Agropyron cristatum和Carex korshinskyi从内蒙古典型草原上的自由放牧和封闭地块采集。重要发现
我们发现从自由放牧区采集的A. cristatum和C. korshinskyi在分株生物量、分株数和总生物量方面比从封闭区采集的受干旱影响较小。从自由放牧地收集的植物对干旱的增强适应性应部分归因于干旱处理下较大的根生物量分配可塑性。我们的研究结果表明,放牧管理可用于提高草地植物对气候变化的适应能力。
