【Objective】The purpose of this project was to provide a theoretical basis for breeding drought-resistance forage by comparatively studying 12 gramineous forage's seedlings under the drought stress.【Method】The study adopted indoor pot experiment on forage for continuous drought stress.【Result】The 12 grass species in drought resistance were divided into three categories: Strong drought-resistance forage has Agropyron cristatum(Linn.) Gaertn.and Arrhenatherum elatius(L.) Mert.et.Kocll;Medium-drought forage has...
