D) IAA and gibberellins
Correct Answer: B
Solution :
Polyethylene Glycol (PEG) and sodium nitrate enhances fusion of protoplasts (protoplast fusion). Protoplast fusion is a physical phenomenon which occurs due to the fusion of protoplast (cell without cell wall) of two or more cells. It can be done by mechanically (spontaneous) or inducing agents.| (i) Spontaneous agents Mechanical fusion |
| (ii) Inducing agents (i) \[NaN{{O}_{3}}\] treatment |
| (iii) High pH or \[C{{a}^{2+}}\] treatment |
| (iv) PEG treatment |
| (v) Electrofusion |
