原始语种摘要: In greenhouse production a temperature drop concept has become an important tool to control stem elongation of a number of ornamental plant species, bedding plants and vegetable transplants. This concept takes advantage of the fact that, in many species, plant stem elongation is sensitive to a short diurnal temperature drop in the morning or in the end of the night. Here, the role of light in cucumber plant ( Cucumis sativus L.) response to a diurnal temperature drop has been investigated. Plants were grown under relatively “low” (120 µmol m-2 s-1 PPFD) or “high” (320 µmol m-2 s-1 PPFD) light intensity. The effect of a 2 h temperature drop from 23° to 9°C, either in the end of the night (in darkness) or in the beginning of the day (in light) on...
