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.
