Horticulture MCQ Question and Answer | Agriculture MCQ Question

The word "Olericulture" is derived from the Latin word.

In horticulture, olericulture specifically refers to the branch that deals with the cultivation of vegetables. The term "olericulture" comes from the Latin word "oleris," which means "kitchen garden" or "vegetable garden." So, the correct answer is Option B: Latin.

The man-made vegetable is Rutabaga.
A man-made (or person-made) vegetable is one that humans have created through cross-breeding and selective breeding. This helps science and the food industry create new varieties of foods with attractive qualities like appearance, texture and flavour.
Rutabaga roots are eaten as human food in a variety of ways and the leaves can be eaten as a leaf vegetable. The roots and tops are also used for livestock, either fed directly in the winter or foraged in the field during the other seasons.

The botanical name of radish is Raphanus sativus.
Radishes are annual or biennial brassicaceous crops grown for their swollen tap roots which can be globular, tapering or cylindrical. The root skin colour ranges from white through pink, red, purple, yellow and green to black, but the flesh is usually white.
Radishes are a fast-growing, annual, cool-season crop. The seed germinates in three to four days in moist conditions with soil temperatures between 18 and 29°C. Radishes grow best in full sun in light, sandy loams, with a soil pH of 6.5 to 7.0, but for late-season crops, a clayey loam is ideal.

Tentruier variety of grape in India is Pusa Navrang.
This hybrid is a cross between Madeleine Angevine and Rubired and was released in 1996. It is an early ripening (1^st week of June), basal bearer and teinturier variety containing red pigment both in peel and pulp. The bunch is loose, medium in size with round and medium-sized berries with TSS ranging from 18 - 20%. It is ideally suited for coloured juice and winemaking and is resistant to anthracnose disease.

Sodium benzoate is the preservative is used for the preparation of tomato ketchup.
Sodium benzoate is a preservative added to packaged foods and personal care products to prolong shelf life.
It is an odourless, crystalline powder made by combining benzoic acid and sodium hydroxide. Benzoic acid is a good preservative on its own, and combining it with sodium hydroxide helps it dissolve in products.

The harvesting stage for watermelon is the full slip stage.
The fruits when mature slip out easily from the vine with little pressure or jerk or if not they will remain separated from the vine the next day. This is called the full slip stage. In some Indian cultivars, green stripes on the skin begin to turn yellow which makes it easy to be harvested.

The hormone used for degreening of citrus fruits is Ethylene.
It accelerates fruit senescence and spoilage. Prolonged exposure of fruit to ethylene or its exposure to high doses during degreening induces physiological disorders and browning of the fruit peel.
Citrus fruits are exposed from 1 - 3 days (depending on the degree of greening) to an atmosphere containing ethylene (5 - 10 ppm) under controlled ventilation, 20 - 26°C and 90 - 95% RH. Conditions for degreening are specific to the production area.

KMnO₄ (Potassium permanganate) is ethylene absorbent among the given options.
Potassium permanganate reduced the concentration of ethylene and calcium hydroxide reduced the concentration of carbon dioxide in sealed polyethylene bags containing bananas.
It was estimated that about two weeks of additional storage life was obtained by packing potassium permanganate with the fruit.

1^st project Coordinator of AICVIP was Dr. Vishnu Swaroop.
AICVIP is all India-coordinated vegetable improvement project.
Initiation of AICVIP with Headquarters at Indian Agricultural Research Institute, New Delhi, headed by a Project Coordinator, Dr. Vishnu Swaroop being the first one who joined the project in 1971.
The main function of AICVIP is to provide a national-level platform for multi-location testing of vegetable technologies developed by various research institutes and state agricultural universities to identify region-specific recommendations.

Glabrous Seedling-a morphological marker for identification of male sterility is found in Muskmelon.
Glabrous refers to a smooth plant surface completely devoid of hair or pubescence in seedling of muskmelon which denotes male sterility.
Male sterility has immense potential for the production of hybrid cultivars of muskmelon. Five recessive nuclear male sterile genes (ms-1, ms-2, ms-3, ms-4, ms-5) are known.
