Step-by-step solution
Synthetic auxin 2 , 4 D is used as a weedicide and is used to remove dicot weed from monocot field.ABA commonly called as stress hormone causes closure of stomata. Ethylene is only gaseous hormone and it causes ripening of fruits.GA causes rapid intermodal elongation in genetically dwarf plants or rosette plants, the phenomenon is known as bolting. Cytokinin was first isolated by autoclaving herring fish sperm DNA.
