(glasshouse condition)) and duration on growth and quality of tomato seedlings. Inhibition of seedling elongation
was observed in all low storage temperatures. Plant height and number of leaves of tomato seedlings decreased with
decreasing temperature. Leaf chlorophyll value of seedlings in control was lower than that at 13oC temperature, but
it was higher than that at 10oC and 7oC temperatures. Chilling injury and curly leaf were observed in seedlings at
10, 7oC temperature after 10 or 20 days in storage, but they were not observed in seedlings at 13oC temperature.
The time of expanding leaf and chilling injury index increased with increasing storage duration. Delay flowering
time increased with increasing storage duration and decreasing storage temperature. 4oC temperature was not
suitable for long-term storage of tomato seedlings. After 10 days in storage, only 37.5% of seedling survival rate
was observed at 4oC temperature, but 100% of seedling survival rates were observed at 13oC, 10oC and 7oC
temperatures after 10 or 20 days in storage. Although almost growth parameters of tomato seedlings decreased with
decreasing temperature after 10 or 20 days in storage, but there was not statistically significant difference between
10 and 7oC temperatures with total root surface area, total root length, and number of root tips. The compactness
of tomato seedlings at 13, 10 and 7oC were similar to that in control treatment after 10 days in storage, but it
decreased with decreasing storage temperature after 20 days in storage.
