>>Plants can ‘hear’ rain coming, spurring them into action
>>Even before water reaches them, the sound of droplets triggers germination in rice plants
>>Rice plants sense the sound vibrations of raindrops hitting the ground
The study involved rice seeds that were already under the water reacting to wave pressure produced by rain drops.
Moreover, the article ignores the question why seeds existing under the water would react to rain - instead surmising many other plant seeds react to the sound of raindrops, presumably on land - without explaining how 'wave pressure' would be created on land.
In my personal experience of growing plants from seeds, I have always noticed large growth spurts after rain compared to watering from the tap. The assumption was just that rain water is better for plants than filtered/treated tap water. It would be interesting to learn that plants are programmed to have a more active period of growth as a response to rain to go beyond the difference of rain vs tap qualities.
I'm not a scientist to know what tests can be done further, but I would find the results interesting either way
