Question 1
4 / -1

Consider the following statement-

(1) ABA act as antagonist against GA

(2) adventitious root growth promoted by auxin

How many correct-

A
only a

B
only b

C
both correct

D
both wrong
Question 2
4 / -1

Hormone involve in adventitious shoot formation-

A
Auxin

B
ethylene

C
GA

D
cytokinin
Question 3
4 / -1

Mark the wrongly matched-

A
Vernalization- Qualitative and Quantitative requirement of low temp

B
Ethephon- release ethylene slowly in plant

C
Zeatin – furfuryl amino purine

D
