Chapter 11 - 3 Photosynthesis : Limiting Factors
Limiting Factors "The actual magnitude of assimilation in a leaf at any moment is determined by one or other of the main controlling conditions, light, temperature, or CO2-supply, acting as a limiting factor." That was the conclusion of Blackman and Smith (1910-1911) in the ninth of their series of papers on vegetable assimilation and respiration. We know that water is another important paramet...
متن کاملLimiting Factors in Photosynthesis: Light and Carbon Dioxide
1. Extensive measurements have been obtained (a) relating photosynthesis and light intensity for a large range of CO(2) concentrations and (b) relating photosynthesis and CO(2) at different light intensities. From these families of curves, the limiting factor relationship can be secured for any value of the photosynthesis rate. 2. In terms of previous work an equation has been derived for descr...
متن کاملLimiting and Experimental Factors
Practical applications of phytoremediation are essential for the clean-up of moderately and severely contaminated sites in an economical and environmentally responsible way. The usage of plants to do a job that would otherwise be done by chemicals or energy intensive soil removal is a natural choice on several levels. First, by using plants for clean-up, pollutants are being absorbed by nature ...
متن کاملLimiting factors for glycogen storage in tumors. I. Limiting enzymes.
The paper presents a study of various enzymes involved in the final accumulation of glycogen in tumor tissues. The solid tumors used are : Novikoff hepatoma, Walker 256 carcinosarcoma, Sarcoma 37, leukemia, and melanoma. It was observed that tumor tissues showed lower activity of phosphoglucomutase and glycogen synthetase as compared with that of normal liver and muscle. All tumors studied exce...
متن کاملFactors limiting bioremediation technologies
The use of microorganisms to destroy, or reduce the concentration of, hazardous wastes on a contaminated site is called bioremediation. Such a biological treatment system has various applications, including, clean up of contaminated sites such as water, soils, sludges, and waste streams. The treatment of the Alaskan shoreline of Prince Williams Sound after the oil spill of Exxon Valdez in 1989 ...
