A new study has rejected the earlier view that that methane is transmitted directly into the air by the plants.

In order to find whether it's true or not, an examination of several possible sources of methane production was done, and it was discovered that plants are not capable of synthesizing methane under normal growth conditions.

Under normal circumstances, water from the soil is taken up by the plants, which then transpire it as water vapour through their leaves. It is worth noticing here that if incase there is methane in the water of the soil; then this methane too would also be taken up and released by plant. This makes us believe that plants have produced methane.

But it is also a fact that under conditions of stress, down of plant matter can release methane.

The findings have been reported in the Proceedings of the Royal Society B: Biological Sciences, which is the Royal Society's flagship biological research journal and is dedicated to the fast publication and broad distribution of high-quality research papers, reviews and comment and reply papers.
