The coefficient of effectiveness (K e) of assimilated CO2 conversion into dry matter of cucumber (Cucumis sativus L.) plants at the stage of four leaves as dependent on a photoperiod (8, 12, and 16 h) at an irradiance of 220 W/m2 at the upper leaf level and the combinations of day and night temperatures: typical temperature of plant habitat (background temperature) of 25°C and heat- and cold-hardening temperatures (35 and 15°C, respectively) was determined in the multifactorial designed experiment. K e reduced insignificantly at shortening of a photoperiod and greater at its lengthening. At background temperatures, K e corresponded mainly to that of carbohydrate synthesis while the presence of cold-hardening temperatures in the thermoperiod increased K e and heat-hardening temperature reduced it.
