Horticulture MCQ Question and Answer | Agriculture MCQ Question

Benzyl adenine is not an anti-gibberellin or growth retardant. It is a first-generation synthetic cytokinin that elicits plant growth and development responses, setting blossoms and stimulating fruit richness by stimulating cell division. It is an inhibitor of respiratory kinase in plants.
Gibberellin is a plant hormone found in seeds, young leaves and roots that cause excessive growth.

Strawberry is the fruit that starts bearing fruit within one year of planting. It does not take years to bear fruits which means it starts fruiting the year it is planted or grown from seeds.
Fruit is typically ready for harvesting 4 - 6 weeks after blossoming.
Strawberry fruit is considered an ‘accessory fruit’ and is not a true berry.

Fruits are blanched before canning at 80°C.
Blanching foods helps reduce quality loss over time.
Blanching is scalding vegetables and fruits in boiling water or steam for a short time. It is typically followed by quick, thorough cooling in very cold or ice water. Blanching stops enzyme actions which otherwise cause loss of flavour, colour and texture.

In 1900, the potato moth came into India (Bombay) from Italy. By the mid 1900s, potato moths became widely distributed in all potato regions in India.
A potato moth is scientifically known as Phthorimaea opercula. It is an oligophagous insect that feeds on the plant family Solanaceae.
Potato tuber moth larvae are known for feeding on the tubers, roots and foliage of potato plants.

Treatment to get rid of fruit flies in mango is VHT.
VHT is the vapour heat treatment system for steadily killing eggs and larvae of fruit flies parasite inside the fruit with vapour and heat without injuring fresh fruits.
This machine is capable of sterilization of a large volume of fresh fruit per use.

In India, the black soil is mostly found in Maharashtra state.
Black soil is the black coloured soil containing a high percentage of humus (4% - 16%) and high percentages of phosphoric acids, phosphorus and ammonia.
These are very fertile soil and can produce high agricultural yields with their high moisture storage capacity.

Jasmine sambac is Arabian jasmine.
It is a climbing, evergreen, shrub in the Oleaceae family, native to tropical parts of Asia. It is probably native to India or Southeast Asia where it is a broadleaf evergreen shrub.
It is known for its continuous production of fragrant flowers during the warmer months of the year, jasmine plants are popular picks for the home and garden.

The Irish famine was caused by Phytophthora.
Irish famine is also known as the Great Irish famine, which occurred in Ireland in 1845 - 49 when the potato crop failed in successive years. The crop failures were caused by late blight, a disease that destroys both the leaves and the edible roots, or tubers, of the potato plant. The causative agent of late blight is the water mold Phytophthora infestans.

Auxin is the plant hormone that promotes the mechanism of apical dominance in plants. It promotes apical dominance by suppressing the activity of lateral buds.
Auxins are a group of naturally occurring and artificially synthesized plant hormones and play an important role in the regulation of plant growth. Auxin means ‘to enlarge’ and enhances cell division, elongation and differentiation, embryonic development, apical dominance and transition to flowering.

The pungent flavor in Radish is due to the presence of Isothiocyanates.
Isothiocyanates are the chemical group formed by substituting the oxygen in the isocyanate group with a Sulphur.
It is the chemical group formed by substituting the oxygen in the isocyanate group with a Sulphur. Naturally, it is produced by enzymatic action and conversion of metabolites called glucosinolates. It is produced in cruciferous vegetables, like bok choy, broccoli, cabbage, cauliflower, radish, kale, etc.
