Keywords: Cucumis sativus L., photoperiod, DROP – short-term temperature reduction, morphogenesis, cold resistance.
It has been demonstrated in experiments with cucumber sprouts that long-term effect of low temperature inhibits the plants' growth and development, reduces accumulation of biomass and modifies its distribution among organs compared with the control. Directivity of the effect of constant low temperature was the same at different photoperiods, including 24-hour illumination. Short-term temperature reductions (DROP) have a morphogenetic effect, with formation of plants with compact growth habit but without affecting dry mass storage and distribution, and significantly enhance the plants' cold resistance. The photoperiod strongly influences manifestation of the response to DROP, but has no effect under constant low temperature impact.
