Options

A. promoting flowering in pineapple
B. induing parthenocarpy in tomato
C. use as herbicides to kill dicot weeds
D. all of these

Answer

D

Explanation

NA A and 2,4-D are often employed for inducing flowering in litchi and pineapple. Application of auxins (e.g., IA A, IBA) and conjugate auxins (e.g., IBA-alanine) to unpollinated pistils make them develop into seedles fruits (or parthenocarps) which carry a better market price than the normal fruits having seeds. 2,4-D and 2,4,5-T are used as weedicides (herbicides) which destroy broad leaved weeds in cereal crops and lawns. Dalapon (2,2-dichloropropionic acid) Kills grasses in broad leaved crops.
