Also humans break or bend crop they do not accelerate there growth!!!!
so for god sake don't ignore the details because you don't want to hear about them.
Does anyone have any good research on this topic specifically?
Phototropism is directional growth in which the direction of growth is determined by the direction of the light source.
Phototropism is enabled by auxins. Auxins are plant hormones that have many functions. In this respect, auxins are responsible for expelling protons (by activating proton pumps) which decreases pH in the cells on the dark side of the plant. This acidification of the cell wall region activates enzymes known as expansins which break bonds in the cell wall structure, making the cell walls less rigid. In addition, the acidic environment causes disruption of hydrogen bonds in the cellulose that makes up the cell wall. The decrease in cell wall strength causes cells to swell, exerting the mechanical pressure that drives phototropic movement.
