Effect of Carbon Dioxide Enrichment and Light
Since they grow nearly exponentially, plants in their juvenile phase can benefit more than mature ones of optimal growing conditions. Transplant production in greenhouses offers the opportunity to optimize growing factors in order to reduce production time and improve transplant quality. Carbon dioxide and light are the two driving forces of photosynthesis. Carbon dioxide concentration can be e...
متن کاملBiological Effects of Carbon Dioxide Enrichment
Increased CO2 concentrations can also “fertilize” plants by stimulating photosynthesis, which models suggest has contributed to increased vegetation cover and leaf area over the 20 century (Cramer et al., 2001). Increases in the Normalized Difference Vegetation Index, a remote sensing product indicative of leaf area, biomass and potential photosynthesis, have been observed (Zhou et al., 2001), ...
متن کاملeffect of carbon dioxide enrichment on morphophysiological characteristics of amaranthus (amaranthus tricolor l.) under salinity stress
to evaluate the effects of various concentration of carbon dioxide and salinity stress on morphophysiological characteristics of amaranthus tricolor l. an experiment was conducted in greenhouse conditions in faculity of agriculture ferdowsi university of mashhad. the experiment was split plot based on completely randomized design with three levels of co2 (380, 700, 1050 µl/l) and three concentr...
متن کاملEffect of Light Intensity on Efficiency of Carbon Dioxide and Nitrogen Reduction in Pisum sativum L.
Photosynthetic efficiency, primary productivity, and N(2) reduction were determined in peas (Pisum sativum L. var. Alaska) grown at light intensities ranging from severely limiting to saturating. Plants grown under higher light intensities showed greater carboxylation and light capture potential and higher rates of net C exchange. Uptake of N(2), computed from measured C(2)H(2) reduction and H(...
متن کاملInfluence of Light and Darkness upon Carbon Dioxide Fixation.
For plants sensitive to photoperiodism light is generally essential for flowering, and the requirement for CO2 with the light indicates a photosynthetic function for the light period (21, 10). There appears to be an additional role of light in which it apparently alters a photoreceptor pigment controlling floral initiation (22). Evidence has been advanced recently that CO2 is also essential dur...
