Production of yield and Acemannan in Aloe plants under Pedo-ecological stresses

Two species Aloe barbedensis and Aloe ferox were cultivated under different irrigation and salinity stress conditions in order to evaluate the yield attributes along with the content of acemannan. The experiment was laid in factorial randomized block design with three replications under pot culture study. The results suggested that high salinity stress alongwith moderate moisture stress condition of the soil were favorable for better growth and yield parameters of Aloe plants. Leaf weight, gel fillet percent, gel percent and acemannan content in both the Aloe species increased under these soil stress conditions. Various levels of salinity and moisture, individually effected the yield parameters. However, at every situation, Aloe ferox gave better performance relative to that of Aloe vera.
