Technical note: Manipulating interactions between plant stress responses and soil methane oxidation rates
<p>It has recently been hypothesised that ethylene, released into soil by stressed plants, reduces the oxidation of methane by methanotroph. To test this, a field trial was established in which maize plants were grown with and without soil moisture stress, and the effects of addition aminoe...

<p>It has recently been hypothesised that ethylene, released into soil by stressed
plants, reduces the oxidation of methane by methanotroph. To test this, a
field trial was established in which maize plants were grown with and without
soil moisture stress, and the effects of addition aminoethoxyvinylglycine
(AVG; an ethylene biosynthesis inhibitor) and biochar (increases soil water
holding capacity and reduces plant stress) were determined following the
static incubation of soil samples. AVG increased methane oxidation rates by
50 % (<i>P</i> = 0.039), but only in the absence of irrigation. No other
treatment effects were observed. This result provides evidence for a positive
feedback system between plant stress, ethylene production, and impacts on
methanotrophic activity.</p> |
