ABA also helps in preventing the loss of dormancy of seed. - Seed germination is inhibited by ABA which is antagonist to gibberellin. - $\mathrm{ABA}$ also helps in the inhibition of the division of cells in the vascular cambium. - The plant genes for ABA biosynthesis and sequence of the pathway have been explained. - ABA plays a central role in induction and maintenance of seed dormancy and also inhibits the transition from embryonic to germination growth. \section*{Seed Dormancy}

Which of the following is not an auxin?
1 IAA
2 IBA
3 Zeatin
4 NAA
Explanation:
C Zeatin is not an auxin - IAA is an auxin from a natural plant. - NAA is commonly used artificial auxin in agriculture. - IBA is most used synthetic auxins in plant propagation.

Choose the correct combinations from the following A. Induce sprouting of Potato tubers Ethylene B. Kill the dicot weeds - Cytokinin C. Increase in Stalk length of grapes Gibberellins D. Induce apical dominance - Auxins
1 A C D
2 B D C
3 B C D
4 A B C
Explanation:
A Gibberelins are the plant hormones that induced sprouting of potato tubers. They do this by stimulating cell division and elongation in the buds, as well as the synthesis of enzymes that are need for growth. - Gibberellins promote elongation of stems and stalks, which can lead to increased stalk length in grapes. - Auxins are plant hormones responsible for controlling the growth of plants. They inhibit the growth of lateral buds, promoting apical dominance where the main stem goows stronger.

Spraying of which of the following phytohormone on juvenile conifers helps in hastening the maturity period, that leads to early seed production?
1 Abscisic Acid
2 Indole-3-butyric Gibberellic Acid
3 Gibberellic Acid
4 Zeatin
Explanation:
C Gibberellins are plant growth regulators that facilitate cell elongation and help the plant to grow taller. - Gibberellines was first isolate by Teijiro yabuta sumuki form fungal strains provided by kurosawa from Gibberella fujikori. - Yabuta named the isolate Gibberellin. - Gibberellin is useful in early seed production in conifers.
