Question

What can a grower do to produce plants that are attractive and full of side branches?
(1) Pinch off the apical meristem to decrease the amount of auxin.
(2) Pinch off the apical meristem to increase the amount of auxin.
(3) Pinch off the intercalary meristems to increase the amount of auxin.
(4) Pinch off the intercalary meristems to decrease the amount of auxin

Answer 1

(2)pinch off the apical meristeam to increas theamount of auxim

Answer 2

The answer is (3). Pinch off the intercalary meristems to increase the amount of auxin.

Intercalary meristems are tissues found between leaf nodes that supprt growth. To produce more leaves and branches, trimming is done to increase auxin (a plant's growth hormone) and stimulate secondary growth.
