Horticulture MCQ Question and Answer | Agriculture MCQ Question

The correct answer is B: Dull sound when fruit is thumped

Here's why:

* Anthesis refers to the flowering stage. While knowing the days after flowering can be helpful, it's not the *most* reliable indicator because weather and growing conditions can affect maturity rates.

* The "thumping" method is a common way to check a watermelon's ripeness.
* A dull, hollow sound usually indicates the watermelon is ripe. The flesh has developed and is full of juice.
* A metallic or ringing sound often means the watermelon is unripe.

* Therefore, judging by the sound is the most practical and quick indicator for ripeness in watermelons.

Lantana (Lantana camera) belongs to the family Vervenaceae.
It is a genus of about 150 species of perennial flowers in the verbena family.
Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. The flowers typically change colour as they mature, resulting in inflorescences that are two or three colored.

Bearing habit of Cocao is Cauliflorous.
Cauliflory is a botanical term referring to plants that flower and fruit from their main stems or woody trunks, rather than from new growth and shoots.
Cacao (Theobroma cacao) is a well-known cauliflorous tree with flowers and fruits that develop on the main trunk and branches. Ground seeds are the source of chocolate. The fruit of cacao (Theobroma cacao) is attached to the main trunk of a small tree. Ground seeds are the source of chocolate.

Cucurbit plants are Vines.
Cucurbitaceae, the gourd family of flowering plants, belonging to the order Cucurbitales and containing 98 genera and about 975 species of food and ornamental plants.
The Cucurbitaceae or vine crop family is a distinct family without any close relatives and includes many important vegetables such as cucumber, melon, watermelon, squash, pumpkin and gourds.
Members of the family are annual or perennial herbs native to temperate and tropical areas.

Suvasini is a Double type of marigold.
This new hybrid bears double flowers on medium spikes. The flower buds are greenish in contrast to pinkish buds in 'Suvasini' and local double.
It is a double-flowered multi-whorled variety released by the Indian Institute of Horticultural Research (IIHR), Bangalore. It is a cross between 'Single' and 'Double'. This variety produces more flowers per spike.

In the metaphase stage of the cell, division chromosomes are arranged on the equatorial plate.
It is a stage of mitosis in the eukaryotic cell cycle in which chromosomes are at their second-most condensed and coiled stage.
The chromosomes, carrying genetic information, align in the equator of the cell before being separated into each of the two daughter cells. This can be referred to as the equatorial plate.

The method followed for the production of inbreds in Self-incompatible lines is Sibbing as well as Bud pollination.
Self-incompatibility (SI) is a general name for several genetic mechanisms that prevent self-fertilization in sexually reproducing organisms and thus encourage outcrossing and allogamy. Sibbing is a process of pollinating an emasculated plant with pollen from a sister plant.
The pollination taking place when the flower is in the bud condition is called bud pollination. It usually occurs in the flowers in which the stigma and the pollen grains mature or ripens even before the opening of the bud. Example Pea, Grass, etc.

The cowpea variety that is unaffected by day length (Photo insensitive) is Pusa Dofasli.
This variety is released by IARI and is a cross between Pusa Phalguni × Philippine selections.
It is photo insensitive, bushy cultivar, and suitable for both summer and rainy seasons. The crop comes to harvest in 55 - 60 days and yields about 7.5 - 8 t/ha.

Strains of Bt produce toxins, which confer resistance against Lepidopteran larvae, Dipteran insects as well as coleopteran insects.
Bt (Bacillus thuringiensis) strains synthesize Crystal (Cry) and cytolytic (Cyt) toxins, at the onset of sporulation and during the stationary growth phase as parasporal crystalline inclusions.
Cry proteins are specifically toxic to the insect orders Lepidoptera, Coleoptera, Hymenoptera, and Diptera, and also to nematodes.
B. thuringiensis serves as an important reservoir of Cry toxins for the production of biological insecticides and insect-resistant genetically modified crops.

Quisqualis indica is a climber.
It is a popular climber in tropical gardens hardy, quick growing and needs strong support.
Rangoon creeper (Quisqualis indica) is regarded as an emerging environmental weed in northern Queensland and the northern parts of the Northern Territory and is a potential environmental weed or "sleeper weed" in other warmer and wetter parts of the country.
