The combined effects of water deficit and heat stress on physiological characteristics of endangered Nouelia insignis

Dry-hot valley is characterized by water deficit and heat stress which often occur simultaneously in the field. Nouelia insignis has become endangered and natural regeneration of the species in the dry-hot valley is limited. Seedlings subjected to each water deficit treatment (achievement by withholding irrigation for 0, 3 and 6 days, respectively) were randomly divided into three groups and transferred to climate chambers set at 25, 40 and 50...
