Salt stress is a limiting factor of plant growth and yield, and becoming a serious problem in the world so in reason to determine salinity effect on aloe growth experiment was conducted in a greenhouse as a bi-factorial in completely randomized experimental design with three replications. Aloe plants irrigated with nutrient solution containing different level of NaCl (0, 2, 4, 6 and 8 ms) on December and harvesting took place three time with one month interval on January, February and March. Results revealed that salinity affected number of leaf, plant height, number of sprout, root weight, plant weight, leaf weight, total gel weight, and root dry weight. Variance analysis also showed that sampling time relieves significant effect on number of leaf, plant height, and root length, number of sprout, root weight, plant weight, leaf weight and total gel weight. All measured characteristics were highest for control. Interaction between salinity and sampling time on plant height, plant weight, leaf weight and total gel weight showed that these traits decreased in all salinity levels when sampled 30 days after transplanting and the lowest value was related to highest salinity. This result was similar 60 and 90 days after transplanting. Interaction between salinity and sampling time on root length showed that the highest root length was obtained in 2 and 4 ms salinity level when sampled 30 days after transplanting. However all salinity levels also decreased root length 90 days after transplanting.
