Excess ethylene (also native plant hormone) can inhibit elongation growth, cause leaves to fall (abscission), and even killthe plant. Some synthetic auxins, such as 2,4-D and 2,4,5-trichlorophenoxyacetic acid (2,4,5-T) were marketed also as herbicides.}$

Answer 2

Answer:

Explanation:

1.Cell elongation: The primary and chief function of auxin in plants is to stimulate the cell elongation in shoot.The growth of cells in length is called cell elongation.

2.Cell division in the cambium: Auxin is responsible for initiation and promotion of cell division in cambium. This effect of auxin is particularly important in secondary growth of stem and differentiation of xylem and phloem tissues.

3.Parthenocarpy: Auxin is well known to induce parthenocarpy in a number of plants.External application of auxin on flowers causes development of seedless fruits in tomatoes ,apples, cucumbers,etc.
