Statements (A,B,C,D) in column I have to be matched with statements (p,q,r,s) in column II.

	List I		List II
A	Parthenocarpy	p	Photoperiodism
B	Apical dominance	q	Development of seedless fruit
C	Extreme cold treatment	r	Vernalization
D	Response to length of the day	s	Auxin

Filo · Accepted Answer

In botany and horticulture, parthenocarpy is the natural or artificially induced production of fruit without fertilisation of ovules, which makes the fruit seedless.
Apical dominance occurs when the shoot apex inhibits the growth of lateral buds so that the plant may grow vertically. The apical bud produces an auxin hormone (IAA) that inhibits growth of the lateral buds further down on the stem towards the axillary bud.
Vernalization is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial equivalent. After vernalization, plants have acquired the ability to flower, but they may require additional seasonal cues or weeks of growth before they will actually flower.
Photoperiodism is the physiological reaction of organisms to the length of day or night. It occurs in plants and animals. Photoperiodism can also be defined as the developmental responses of plants to the relative lengths of light and dark periods.

So, the correct answer is 'A-q, B-s, C-r, D-p'.
