Effect of temperature and photoperiod on efficiency of assimilated CO2 conversion into the biomass of Cucumis sativus

Effect of temperature and photoperiod on efficiency of assimilated CO2 conversion into the... 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. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Russian Journal of Plant Physiology Springer Journals
