Ecological Factors that Affect the Growth of Plants (With ...

ADVERTISEMENTS: The ecological factors that affect the growth of plants and determine the nature of plant communities are divided into three types. The three types of ecological factors are: (1) Climatic factors which include rainfall, atmospheric humidity, wind, atmospheric gases, temperature and light (2) Physiographic factors which include altitude, effect of steepness and sunlight on [.]

Light Pollution Affects Plants in the Environment

In the early days of street lighting, the lamps used most commonly were either low-intensity whitish incandescent filaments or higher intensity, bluish fluorescent, mercury vapor, or metal halide lamps. While these sources highly attracted insects, they had little effect on plants because of their low levels of red or infrared light.

Dress Up Your Home With These Indoor Plants That Don't ...

May 31, 2018 · Since most indoor plants are tropical plants, they thrive in low, indirect and bright lights. Normally, direct sunlight is about 32,000-100,000 lux, i.e. the unit of illuminance. 100 lux or less is considered low intensity or indirect lighting, and about 400 lux would be bright lighting.

The Best Light Intensity for Plants Indoors - Sunday Gardener

Dec 25, 2018 · The Best Light Intensity for Plants Indoors. If you wish to grow healthy plants indoors, it's important to understand their basic needs. The most important elements you need to provide are water and adequate light. All of the other factors, such as the type of soil, container or fertilizer, while important, are not as vital as these ones.

Compensation point - Wikipedia

The (light) compensation point is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration.At this point, the uptake of CO 2 through photosynthetic pathways is equal to the respiratory release of carbon dioxide, and the uptake of O 2 by respiration is equal to the photosynthetic release of oxygen.

Apr 11, 2019 · It does not mean that the intensity of radiation is lower in South Africa than Nigeria per se. It also depends on the angle and direction of the land, covering material and local weather conditions. We are discussing high intensity radiation on plants throughout the whole year. It does not mean winter sun has low intensity per se.

Fire Effect on Soil - Northern Arizona University

The effects of fire on soil microbes is dependent to a large extent upon fire intensity. The responses of soil microbes to fires range from no detectable effect in low intensity fires to total sterilization of the surface layers of soil in very hot wildfires (see Joergensen and Hodges 1970; and Renbuss et al. 1973).

The structural response of photosystem II (PSII) and its light-harvesting proteins (LHCII) in Arabidopis thaliana after long-term acclimation to either high or low light intensity was characterized. Biochemical and structural analysis of isolated thylakoid membranes by electron microscopy indicates a distinctly different response at the level of PSII and LHCII upon plant acclimation.
