The effects of a daily short-term low temperature treatment (DROP) applied during different pre-reproductive developmental stages on growth and development of tomato plants grown under continuous light (CL) has been studied. It was shown that DROP treatment applied to plants of different age is nor equally effective in in preventing or moderating CL injury in tomatoes grown under CL. DROP treatment (daily decrease of temperature from 26 to 12 °C for 2 h) of seedlings and juvenile plants proved to be ineffective in preventing leaf chlorosis in the aftereffect. DROP treatment of immature and virginile plants had moderate protective effect, reducing the degree of leaf chlorosis. Maximum effect was obtained when plants were treated by DROP throughout the whole prereproductive period.
