TIBA
BAP
2, 4-D
Seedless fruits can be induced by
ABA and IAA
ABA and Zeatin
IAA and GA3
Ethylene and ABA
Fruit and leaf drop at early stages can be prevented by the application of:
Ethylene
Auxins
Gibberellic acid
Cytokinins
Which of the following plant activity is not an example of growth promotion activity?
Germination of seeds
Cell division
Delay in senescence
Abscission
Cytokinin involves
Kinetin, zeatin, BAP
GA3, IBA, Kinetin
Zeatin, GA3, BAP
IAA, Zeatin, kinetin
Which of the following statement is wrong about Abscisic acid :
It helps in general plant metabolism
It is antagonistic to GA3
It helps in seed maturation & dormancy
Morphogenesis
Vernalization
Help in shortening the period between germination and flowering
Is useless for monocots
Is high temperature treatment to some annual crops
More than one option is correct.
Removal of shoot tips is a very useful technique to boost the production of tealeaves. This is because :
Gibberellins delay senescence of leaves.
Gibberellins prevent bolting and are inactivated.
Auxins prevent leaf drop at early stages.
Effect of auxins is removed and growth of lateral buds is enhanced.

Cytokinins
Ethylene
Auxins
Gibberellin
