Question

enlist the application of ethylene

Answer 1

Hey,

-Ethylene is a simple gaseous PGR.

-It is synthesised in large amounts by tissues undergoing senescence and ripening fruits.

-It induces triple response in Dicots.(horizontal growth of seedlings,swelling of axis,apical hook formation.)

-promotes senescence and abscission of plant organs.

-effective PGR in in ripening fruits.

-breaks dormancy& induces germination.

-promotes rapid internode/petiole elongation in deep water rice plants.

-promotes root growth and root hair formation.

-initiate flowering in mango and pineapple.


HOPE THIS HELPS YOU.

Answer 2

Explanation:

Applications (Physiological effects) of Ethylene:

• Ethylene plays an important role in breaking the dormancy of seeds and buds. It also overcomes dormancy of potato tubers.

• Ethylene inhibits the elongation of stem and roots in dicots.

• Ethylene plays an important role in commercial ripening of fruits. Thus plays a significant role in post - harvest technology.

• Ethylene promotes senescence besides abscission of organs like leaves and flowers.
