The naturally available cytokinin like substance in plants is
1 Kinetin
2 Zeatin
3 Both (1) and (2)
4 None of these
Explanation:
Kinetin does not occur naturally in plants. Search for natural substances with cytokininlike activities led to the isolation of zeatin from corn-kernels and coconut milk.

In tissue culture which PGR find its use
1 Auxins, cytokinins
2 Cytokinins only
3 Auxins, GA
4 GA, cytokinins
Explanation:
In tissue culture auxins and cytokinins finds its use. The shoot and root development in culture is controlled by auxin-cytokinin balance. More auxins promote root development and more cytokinins promote shoot development.

The affect of apical dominance can be overcome by which of the following hormone:
1 IAA
2 Ethylene
3 Gibberellin
4 Cytokinin
Explanation:
The affect of apical dominance can be overcome by cytokinins. Cytokinin is antagonistic to the auxins in this aspect and helps overcome apical dominance.

Zeatin was isolated from what?
1 Corn kernels
2 Coconut milk
3 1 and 2
4 None of them

Which of the following is not a function of cytokinin?
1 Promotes apical dominance.
2 Promotes chloroplast development.
3 Promotes movement of nutrients.
4 Delay leaf senescence.
Explanation:
Cytokinins are mildly basic growth hormones which are usually amino purine derivatives and promotecell division in plants. Cytokinins inhibit apical dominance while auxins promote apical dominance.
