pyrogallic acid in germination expermiment give advantage
Answers
Explanation:
In one experiment it was found that catechol, gallic acid or pyrogallic acid significantly decreased the germination percentage, growth of radicle and hypocotyls and the fresh and dry weight of cucumber seedlings. Among them, pyrogallic acid was the inhibitor (Ali et al., 2012) .

The aquatic plant Myriophyllum spicatum produces pyrogallic acid. When in alkaline solution, it absorbs oxygen from the air, turning brown from a colourless solution. It can be used in this way to calculate the amount of oxygen in air, notably via the use of the Orsat apparatus.
Gibberellic acid is a natural plant hormone that can be used to speed up the germination of seeds. It is mostly used on seed that is difficult to germinate or ones that takes a long time to germinate.
