It takes very long time for pineapple plante to produce flowers. Which combination of hormones can be applied to artificially induce flowering in pineapple plants throughout the year to increase yield?
- Auxin and Ethylene
- Gibberellin and Cytokinin
- Gibberellin and Abscisic acid
- Cytokinin and Abscisic acid
View Solution
5.
Auxin can be bioassayed by
- potometer
- lettuce hypocotyl elongation
- Avena coleoptile curvature
- hydroponics.
View Solution
6.
Typical growth curve in plants is
- stair-steps shaped
- parabolic
- sigmoid
- linear.
View Solution
7.
Fruit and leaf drop at early stages can be prevented by the application of:
- Ethylene
- Auxins
- Gibberellic acid
- Cytokinins
View Solution
8.
What causes a green plant exposed to the light, on only one side, to bend towards the source of light as it grows?
- Light stimulates plant cells on the lighted side to grow faster.
- Auxin accumulates on the shaded side, stimulating greater cell elongation there.
- Green plants need light to perform photosynthesis.
- Green plants seek light because they are phototropic.
