چکیده مقاله:
Aloe vera is a valuable medicinal plant, whose value mainly refers to its leaf and gel. Salinity, as an abiotic stress, can negatively affect its morphological characteristics as well as quality and quantity of some phyto-chemical compounds of leaf and leaf gel including total phenol, total soluble sugars and its components including sucrose, glucose, and fructose. To investigate the impact of salinity stress on morphological and physiological traits of plant, different levels of NaCl including ۰ (control), ۵۰, ۱۰۰, ۱۵۰, ۲۰۰ and ۲۵۰ mM were applied in a complete randomized design with three replications under greenhouse conditions. The results indicated that the salinity stress has significant negative effect on morphological traits including plant weight, leaf length, leaf weight, gel weight, root length; and also biochemical traits such as total phenol, total soluble sucrose, glucose and fructose. The result of experiments indicated that salinity stress has significant negative effect on morphological traits which results in yield loss. Moreover, biochemical traits such as photosynthetic and defenses of plants were affect by stress. It was concluded that Aloe vera is a susceptible crop to salinity stress
