How will you induce lateral branching in a plant, which normally does not produce them ? Give reason in support of your answer.

Lateral branching in a plant can be induced by removing the apical bud. Auxin causes the phenomenon of apical dominance, i.e. suppression of development of lateral buds into branches in the presence of apical bud. This suppresses the growth of the lateral buds. On removal of the apical buds, Auxin hormone is removed and the inhibition of apical dominance can be overcome to allow the lateral branches to develop.

Would you expect soyabean plants to flower, if given a daily exposure of 15 hours ? Give reasons

Soyabean plants are short day plants which initiate flowering when the day length becomes shorter than a critical length. They remain vegetative if day length is in excess of the critical duration of light. Therefore, soyabean plants will not flower if given a daily exposure of 15 hours.
