Abstract
In the non-cultivated land resources of sea-beach of Hainan province in China,field experiments were conducted to research changes of growth and physico-chemical items such as water content,total solids content,pH value,relative density,absorption,calcium,magnesium,polysaccharides and aloin in the whole leaf juice of Aloe vera and its gel juice under long-term different concentrations of seawater irrigation.Results indicate that when the seawater concentration is lower than 10%,fresh weight of Aloe vera has an increase,but when the seawater concentration exceeds 50%,it is reduced significantly.The number of leaves of Aloe vera plant with lower concentration of seawater has no significant change in comparison with the control,while when the seawater concentration is higher,the number of leaves of aloe plant is reduced markedly.Water content of Aloe vera under seawater irrigation has no significant difference compared with the control(freshwater irrigation),as well as pH,relative density of gel juice and absorbency of the whole leaf juice.However,Ca2+ content in the whole leaf juice of Aloe vera and its gel juice in all seawater treatments,and polysaccharides content in the whole leaf juice irrigated with 25% and 50% seawater increase obviously compared with the control.After seawater irrigation,the aloin content in the whole leaf juice and the height of Aloe vera plant decrease sharply,whereas Mg2+ content in the whole leaf juice and gel juice increases sharply.According to the results,it can be concluded that Aloe vera irrigated by 0% to 50% seawater has higher yield and much more polysaccharides,calcium and magnesium contents,but the aloin content in the whole leaf juice and its gel juice is lower than that of the control.
