Seasonal photosynthetic responses to light and temperature in
curves were measured seasonally in seedlings of white spruce (Picea glauca (Moench.) Voss) grown for two years in the understory of aspen (Populus tremuloides Michx.) or in the open in central Alberta. Light-saturated rate of net photosynthesis, the optimum temperature for net photosynthesis, transpiration rate, photochemical efficiency, and stomatal and mesophyll conductances increased from sp...
متن کاملLight signals and flowering.
Physiological studies over a long period have shown that light acts to regulate flowering through the three main variables of quality, quantity, and duration. Intensive molecular genetic and genomic studies with the model plant Arabidopsis have given considerable insight into the mechanisms involved, particularly with regard to quality and photoperiod. For photoperiodism light, acting through p...
متن کاملResponses of soybean yield and yield components to light enrichment and planting density
Light intensity intercepted by the soybean canopy during the reproductive period is an important environmental factor determining soybean yield components and grain yield. A 2-year field experiment was conducted to investigate the effects of light enrichment and its interaction with planting density on yield formation of soybean cultivars. Light enrichment increased seed yield per plant and yie...
متن کاملPineal and Hypophyseal Responses to Selenium Treatments in Light Deprived Adult Female Wistar Rats
Dark is a generally known potent stimulus for melatonin secretion. Studies have also reported that pineal and hypophyseal endocrine secretions are influenced by nutritional factors. The study was designed to investigate the combined effect of selenium supplementations and light deprivation on pineal and hypophyseal secretions in female Wistar rats. 36 female cyclical Wistar rats were divided in...
متن کاملEffects of Plant Size, Temperature, and Light Intensity on Flowering of Phalaenopsis Hybrids in Mediterranean Greenhouses
Mediterranean greenhouses for cultivation of Phalaenopsis orchids reproduce the warm, humid, and shaded environment of tropical underbrush. Heating represents the highest production cost, due to the high thermal requirements and the long unproductive phase of juvenility, in which plants attain the critical size for flowering. Our researches aimed to investigate the effect of plant size, tempera...
