How do Auxins affect Plant growth?
Auxins are powerful plant growth hormones (or plant growth regulators) produced by plants. They are found in the shoot and root tips and promote cell division, stem and root growth. Auxins are involved in phototropism, geotropism, hydrotropism and various other developmental changes.
What are Antitranspirants? How do they Reduce Water Loss in Plants?
Antitranspirants are the materials or chemicals which are capable of reducing the water loss from plant leaves. Almost 99 per cent of the water absorbed by the plant is lost in transpiration. Since water loss normally occurs through the stomatal pores in the leaves, anti-transpirants are usually foliar sprays.
