Morphological, Biochemical and Soluble Sugars Characters of Aloe vera Subjected to Saline Condition

Aims:Salinity is one of the factors limiting the growth and survival of the plants, stops their growth by interactions such as osmotic potential and toxicity and makes the nutrition imbalance. Methods: The research examined the salinity effect on pharmaceutical Aloe Barbadensis plant; the plant was irrigated with half percent Hoagland nutritional solution containing different rates of Sodium chloride (0, 6, 12 & 18 dS/m) and the plants were harvested in 15 and 45 day intervals. Results:The following morphologic specifications were tested: the plant height, the leaf and root length, the leaf thickness and breadth, the weight of wet shoot and root, the weight of dry shoot and root and the weight of the gel and gel soluble sugars in Aloe vera leaves. In addition, the concentration of Na, K, Cl and Ca of the shoot and root and K/Na and Ca/ Na ratio were examined. Conclusions:One of the most important Aloe Vera's tolerance mechanisms may be the creation of appropriate K/Na , Ca/Na ratio in the shoot in primary time of the tension namely in 15 days and also the salinity rates create many fluctuations on the soluble sugars rates especially glucose and xylose
