Physio‐ecological responses of different Elymus dahuricus and Elymus sibiricus to soil drought stress

摘要

Elymus dahuricus Turcz.and Elymus sibiricus L.are important grasses and are of great value for establishing perennial artificial grasslands and ecosystem restoration.However, most parts of north China are drought and rainless, water stress is the most common factor that limited plant growth (Liu et al.,1994).The goal of this study was to study the change of morphological characters and physiological and biochemical characters of every Elymus dahuricus and Elymus sibiricus materials from different habitats under different drought stress in seeding stage.
