Description
Summary:Experiments were conducted in two Aloe vera cultivars (F0 and F50) tostudy the characters of physiology and ecology under salt stress. The resultsindicate decreases in tissue water, total soluble sugars and glucose, andincreases in dry matter and membrane injury occurred both in F0 and F50irrigated with 60% seawater. Less cell membrane injury were observed in F50.Moreover, total soluble sugars in F0 decreased obviously, however, nosignificant change in F50, while sucrose in plants had no significant change.Furthermore, F0 and F50 accumulated more inorganic cations in stems androots. In addition, leaf K super(+) and Ca super(2+) contents were more in F50 thanthat in F0 to maintain normal plant growth though accumulation of Na super(+).F50 had a relative superiority in growth under salinity conditions due tohigher K super(+)/Na super(+) ratio and lower Na super(+)/Ca super(2+) ratio than F0.
