Influence of Hydrogen Fluid on Plants in Natural Conditions and a Model Experiment.

In places of hydrogen emanation, prolonged exposure to significant concentrations of hydrogen under natural conditions led to the inhibition or death of agricultural plants. Under the conditions of model experiments, it was shown that plants in a short-term current of hydrogen experience stress, which negatively affects their physiological functions. Different types of plants reacted differently both to the effect of molecular hydrogen and to the removal of its load. In experiments with watercress, plants did not recover after the removal of the hydrogen load but died after a triple exposure. Wheat was less sensitive; the plants were only stably (30%) depressed during the whole observation period. [ABSTRACT FROM AUTHOR]
