Plant Hormones and Response

• Prevents premature fall of leaves, flowers, fruits

• Apical dominance, IAA in apical bud suppresses the growth of lateral buds

• Prevents premature fall of leaves, flowers, fruits

• Helps in cell division and xylem differentiation

• Induces parthenocarpy

• Induces the formation of hydrolytic enzymes such as lipase, amylase in the endosperm of germinating cereal grains and barley seeds

• Breaks seed dormancy

• Elongation of the stem and reverses dwarfism

• Helps in overcoming apical dominance induced by auxins

• Stimulate the formation of chloroplast in leaves
