However, as oxygen is also important for plant respiration, storing plant materials in anaerobic conditions produces unpleasant flavors and unappealing colors.

Oxygen by itself or in the molecules of HO or CO are necessary for plant cellular respiration.

Among the possible feedbacks, for example, are changes in the earth's ability to reflect sunlight and in the amount of water entering the atmosphere because of plant respiration.

As air moves northward, the CO2 concentration is modified by the action of sources (fossil fuel combustion, plant respiration, biomass burning, cement production) and sinks (photosynthesis).

In botany he is notable for his early studies of plant respiration and growth.

Here is his description of plant respiration:

When plant respiration occurs below-ground in the roots, it adds to soil respiration.

Increases in soil nitrogen have been found to increase plant dark respiration, stimulate specific rates of root respiration and increase total root biomass.

About 48-60% of the GPP is consumed in plant respiration.

With Gaston Bonnier (1853-1922) he performed extensive research of plant respiration, transpiration and carbon assimilation.
