Seedless watermelons are obtained by
1 triploidy
2 gibberellin application
3 haploidy
4 vegetative propagation
Explanation:
A Seedless watermelons are produced on triploid plants (3 sets of chromosome). Which come from the cross of diploid ( 2 sets) and tetraploid (4 sets) plants.

Which one of the following plant function is not controlled by auxins?
1 Apical dominance
2 Phototropism
3 Growth
4 Photosynthesis
Explanation:
D Apical dominance, phototropism and growth are plant function that is controlled by auxins but photosynthesis is not controlled by auxins. Photosynthesis is a light dependent anabolic process which is not dependent on auxin hormone.

Polyploidy can be induced by the application of
1 auxin
2 kinetin
3 colchicine
4 ethylene
Explanation:
C Polyploidy can be induced by the application of colchicine. An organism having more than two sets of chromosomes is called polyploid. It is especially common in plants. Polyploidy is the presence of three or more chromosome set in an organism. Colchicine chemical is used for induction of polyploidy.

Although the seeds are rich in auxin glucosyl esters, still they do not exhibit any physiological change like growth. The reason is:
1 they are prime examples of bound auxins
2 they are example of bound auxins that are inactive until IAA is released by enzymolysis
3 that they are examples of free auxins
4 none of the above
Explanation:
B Although the seeds are rich in auxin glucosyl esters, still they do not exhibit any physiological change like growth. The reason is that they are example of bound auxins that are inactive untill IAA is released by enzymolysis. Hence, option (b) is correct.
