Question

It takes a very long time for pineapple plants to produce flowers. Which combination of hormones can be applied to artificially induce flowering in pineapple plants throughout the year to increase yield?
A. Auxin and Ethylene
B. Gibberellin and Cytokinin
C. Gibberellin and Abscisic acid
D. Cytokinin and Abscisic acid

Answer 1

Plant hormones influence all parts of plants, from blossoming to fruit setting and development, and from phototropism to leaf fall. Possibly, every cell in a plant can deliver plant hormones. Five significant plant hormones are generally depicted: auxins, cytokinins, gibberellins, ethylene, and abscisic acid.

Complete answer:
Out of a mix of hormones that can be applied to artificially induced blooming in pineapple plants to increase the yield of Auxins and Ethylene. Ethylene is a gas produced by ripened fruits. For what reason does one rotten apple ruin the entire bundle? Ethylene is utilized to mature harvests simultaneously. Sprayed on a field it will make all fruits get ripened simultaneously so they can be harvested.
Both ethylene and auxins hormones are likewise useful for the blooming and fruiting synchronization. They are responsible for development and maturation too.
Auxin is a growth hormone that advances cell division and ethylene helps in expanding root development and ingestion surface zone for plants. Auxins advance stem extension, repress development of parallel buds (keeps up apical predominance). They are produced in the stem, buds, and root tips. Eg., Indole Acetic Acid (IAA).
Auxin is a plant hormone delivered in the stem tip that advances cell stretching or cell elongation. Auxin moves to the darker side of the plant, causing the cells there to become bigger than comparing cells on the lighter side of the plant. This delivers a bending of the plant stem tip toward the light, a plant development known as phototropism.
Cytokinins advance RNA union and stimulate protein and compound exercises in tissues. Kinetin and benzyl-aminopurine are the most regularly utilized cytokinins in plant cells. The Gibberellins are fundamentally used to instigate plantlets.
Abscisic acid (ABA) and gibberellins (GAs) are notable phytohormones that are associated with managing seed germination in Arabidopsis. These two hormones direct seed germination.
It has been perceived that cytokinins are plant hormones that impact not just various parts of plant development, advancement and physiology, including cell division, chloroplast separation and postponement of senescence yet the cooperation with different living beings, including microorganisms. Abscisic acid (ABA) is a significant phytohormone controlling plant development, improvement, and stress reactions.

Note: Auxin additionally assumes a part in keeping up apical dominance. Most plants have parallel (here and there called axillary) buds situated at nodes. Buds are embryonic meristems kept up in a lethargic state. Auxin keeps up this dormancy. However long adequate auxin is delivered by the apical meristem, the parallel buds stay lethargic. In the event that the summit of the shoot is taken out, the auxin is not, at this point produced. This will make the parallel buds start to develop and break their dormancy. Essentially, the plant gets bushier.
