plants produce hormones to coordinate and control growth and responses to light (phototropism) and gravity (gravitropism). unequal distributions of auxin cause unequal growth rates in plant roots and shoots.
what is important in plant growth?
gibberellins are important in initiating seed germination
ethene controls cell division and ripening of fruits
uses of plant hormones?
plant growth hormones are used in agriculture and horticulture
auxin is used as weed killer, rooting powders, promoting growth in tissue culture
ethene is to control ripening of fruit during storage and transport
gibberellins are used to end seed dormancy, promote flowering, increase fruit size
