What are Hormones?
Plant hormones are chemical substance that are used to control growth and development in plants
influenced physiological responses to environmental stimuli.
What do Hormones Regulate?
Why are hormones used in horticulture?
to improve crop production/ performance and yield
Types of plant hormones
Promotes cell division
delays ageing in plants
ensure roots and shoots grow at even rates
assist in the formation of ATP
used in the cultivation of fruits
inhibits plant growth
initiates stress response
responsible for shedding of leaves and fruits
stimulates protein storage
stimulates maturation and aging
ripening of fruit
transported between plant cells through spaces
used in vegetation propagation
produced in growing tips
influences ability to absorb water, cell division and cell stretching
High concentrations are toxic
amount of water
amount of cotton wool
volume of hormone
number of seeds per petri dish
individual seed growth
