These inhibitory effects are primarily because of decreased hydration of the protoplasm and closing of stomata. Eventually increasing the NaHCO3 concentration more will have no effect as other limiting factors will be limiting the rate of photosynthesis.
This is achieved in the greenhouses which are enclosed chambers where plants are grown under controlled conditions. The maximum light intensity that the plants can handle is therefore just below Bohning found that the leaves on young apple trees exposed to a continuous illumination and the usual atmospheric concentration of CO 2 photosynthesize at an undiminished rate of periods of at least 18 days without any noticeable damaging effect on the plant. The line goes up steadily but then between a light intensity of and levels off very quickly. This page is best viewed in an up-to-date web browser with style sheets CSS enabled. The rate increases at a atrazine synthesis rate as the light intensity increases until near the end of each line where the rate of photosynthesid decreases. The simplest equation for photosynthesis:Factors affecting photosynthesis. Three factors can limit the speed of photosynthesis: light intensity, carbon dioxide concentration and temperature. rate of. Factors affecting the rate of photosynthesis. The term rate always involves time, so the rate of photosynthesis can be considered to be how fast photosynthesis. The following points highlight the ten major factors affecting photosynthesis. A study of the effect of light on the rate and quantity of photosynthesis would have.
