选用大花萱草的两个品种‘吉星’和‘紫蝶’作为研究对象,通过土壤干旱胁迫方式使植物体快速失水,用以研究大花萱草在干旱条件下植株形态及生理指标的变化情况等,从而探讨其抗旱生理机制。
Two varieties of Hemerocallis fulva were used as the research object, the rapid dehydration of plants through soil drought stress was used to study the changes of plant morphology and physiological indexes of Hemerocallis fulva in drought conditions So as to explore its physiological mechanism of drought resistance.
