| Abstract: | The effect of nightly temperature drops of different durations (2, 4, and 6 h) on the processes of apical and axillary meristem organogenesis was studied in young Cucumis sativus L. under short photoperiod (day/night, 10/14 h), long photoperiod (16/8 h), and continuous light. Nightly temperature drops for 2 h had no effect on cucumber development under all studied photoperiods; however, longer temperature drops (4–6 h) accelerated the development under long photoperiod and continuous light. Short-term exposures to low temperature under continuous light considerably increased lateral branching of cucumber plants. |
