Control of continuous irradiation injury on tomato plants with a temperature drop: Effectiveness evaluation

Effects of daily short-term low temperature treatment (DROP) applied during different prereproductive developmental stages on growth and development of tomato plants grown under continuous light (CL) has been studied. It was shown that DROP treatment (daily decrease of temperature from 26 to 10 C fo...

Description
Summary:Effects of daily short-term low temperature treatment (DROP) applied during different prereproductive developmental stages on growth and development of tomato plants grown under continuous light (CL) has been studied. It was shown that DROP treatment (daily decrease of temperature from 26 to 10 C for 2 h) applied to plants of different age is not equally effective in preventing or moderating CL injury in tomatoes grown under CL. DROP treatment of seedlings and juvenile plants proved to be ineffective in preventing leaf chlorosis in the aftereffect. DROP treatment of immature and virginile plants of different age had moderate protective effect, reducing the degree of leaf chlorosis. The maximum effect was obtained when plants were treated by DROP throughout the entire prereproductive period.
