3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect.
Explanation:
Cytokinins cause delay in senescence of plant tissue, it is negative senescence regulator, if a small spot on a leaf treated with cytokinin, that spot remain green after surrounding tissues on the same leaf begin to senescence. Cytokinin is involved in the formation, maintenance and growth of shoot apical meristem; it is a positive regulators of cell division in shoot apical meristem and negative regulator in the root apical meristem.
