commercial use of plant hormones

auxin can be commercially used to kill weeds how

auxin is used in selective weedkillers which target only plants with broad leaves

they disturb their growing patterns which eventually kills them off

auxin can be used to grow plants from cuttings with root powder how

root powder contains auxin if you add this to the soil where a cutting is the plant will grow-cloning

auxin can be used is tissue culture how

again plants are being cloned but only with a few cells

auxin needs to be added to growth medium to stimulate cell division and formation of roots and shoots

gibberellin is a type of plant growth hormone which helps with

seed germination stem growth and flowering

gibberellin controls dormancy what is dormancy

when a seed has to go through certain conditions in order to germinate

gibberellin helps alter dormancy for two reasons

seeds can germinate at times of year they normally wouldn`t

a batch of seeds will of germinate at the same time

gibberellin can induce flowering

some plants needs certain conditions to flower giberelin allows them to flower without these changes in environment

the last thing gibberellin helps with is

growing larger fruit

what is ethene

ethene is a gas produced by aging parts of plant it influences grow by controlling cell division

stimulates enzymes to ripen fruit

ethene can speed up or delay ripening why is this important

fruit can be transported and ripened when it gets there

there are chemicals that stop effects of ethene or stop plant producing it`s ethene
