Growth Substances in Plants
Growth substances are compounds of a hormonalnature which, although present in the plant in extremely low concentrations, govern the life of the plant. 1\-1:uch regarding these substances is still obscure. Until recently it was thought that the chemical structure of all c~mpounds with growth substance activity (both natural and synthetic) conformed to two essential requirements, but the members...
متن کاملCarbon dioxide enhancement of tree growth at high elevations.
dcotide sequence reported by Lochrie et al. (24) differs in many respects from the sequence reported by Tanabe et al. (25), Medynski at al. (26) or Yatsunami and Khorana (27). The differences in nudeotide sequences of a-transducin cDNA's may be due to differences between bovine strains (24). Alternatively, the species of ot-transducin cDNA described by Lochrie et al. may be expressed in cones, ...
متن کاملEffect of carbon dioxide and light on ethylene production in intact sunflower plants.
High CO(2) concentration (0.5%) increased the rate of ethylene production, measured in a continuous flow system, in intact sunflower (Helianthus annuus L.) plants. However, the rate of ethylene production subsided to near control levels after approximately 24 hours. The effect of high CO(2) could only be observed in light. Although high CO(2) concentration had no effect on the rate of ethylene ...
متن کاملEffect 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 کاملThe Influence of Light and Carbon Dioxide on Photosynthesis
1. An optical system is described which furnishes an intensity of 282,000 meter candles at the bottom of a Warburg manometric vessel. With such a high intensity available it was possible to measure the rate of photosynthesis of single fronds of Cabomba caroliniana over a large range of intensities and CO(2) concentrations. 2. The data obtained are described with high precision by the equation K...
