چکیده
Air temperature and light conditions are important factors not only to produce high-quality seedlings but also promote energy efficiency in a plant factory with artificial lighting. In this study, we conducted two experiments order investigate the favorable of air temperature, intensity photoperiod for production cucumber scions rootstocks Cucumber were cultivated combined treatments: combination three different levels difference between day night (DIF), 25/20, 26/18 27/16 °C five photosynthetic photon flux, 50, 100, 150, 200 250 ?mol·m?2·s?1 was set first experiment, conditions, 12, 16 20 h·d?1 second experiment. treatments, hypocotyl elongation affected more largely by than DIF. The highest DIF treatment (27/16 °C) negatively on accumulation dry mass. On contrary, smallest (25/20 seedling growth due lesser stress rapid change photo- dark-period. an increased DLI (daily integral) promoted rootstocks. Under same condition, increasing decreasing intensity. both experiments, while weight intensity, use efficiencies reduced Considering quality efficiency, optimal environment represented 25/20 150 photoperiod.

Sunlight, as a natural resource, is an important factor in agriculture, which is supplied indefinitely and without any charge by the sun. But some phenomena such as cloudy weather or shortening the length of the day throughout the year, cause restrictions on access to this important source. This is very important for cultivation in controlled environments such as greenhouses, which usually prod...
