Tiliaceae is a family of flowering plants. It is being sunk in Malvaceae.
Grewia asiatica, commonly known as phalsa or falsa, is a species of flowering plant in the mallow family Malvaceae (Tiliaceae). It was first found in Varanasi, India and was taken by Buddhist scholars to other Asian countries and the rest of the world.
The fruit is an edible drupe 5 - 12 mm in diameter, purple to black when ripe.

China was the world's largest producer of cauliflower, accounting for 44% of total production followed by India with 29% of the world's total. China and India produce together more than 70% of the world's total cauliflower and broccoli.
In 2020, cauliflower production in China amounted to approximately 9.5 million tons. Cauliflowers are original from Asia, where they are known for many centuries. However, their spreading to other continents did not take place until the 18^th century. At present, it is mainly cultivated in Asia and the main producing countries are India, China, Italy and France.

Oil palm is pollinated by Weevil.
Weevils are beetles belonging to the superfamily Curculionoidea, known for their elongated snouts. They are usually small, less than 6 mm in length and herbivorous.
The pollinating weevil, Elaedobius kamerunicus (EK) has been known to be the most efficient insect pollinator of oil palm and has successfully improved oil palm pollination and increased the yield.
Pollination occurs because this beetle is attracted by the scent of flowers, especially male flowers that are stronger in aroma than female flowers. Its introduction has greatly reduced the need for assisted pollination.

The major post-harvest problem in Gerbera is Conking.
Gerbera daisies can suffer from conking, a condition that causes the stem to become weak and fold in half.
Cold storage at night helps minimize conking problems. Preventing dehydration and bacterial growth in the water also helps keep Gerbera flowers upright.

Pant shubhra and Pusa shubhra are varieties of Cauliflower.
Pant Shubra is a mid-season variety. This variety is characterized by semi-erect outer leaves. Inner leaves partially cover the curds which are compact, slightly conical, non-ricey, and off-white. This variety produces marketable curds by December - January. It takes about 120 days to produce marketable curds from nursery sowing. The yield potential of this variety is 250 q/ha.
Pusa Shubhra is a variety of cauliflower. It belongs to the third maturity group. It is suitable for the rainy season. Curds are compact, a bit conical, creamish white and non-leafy.

Mangla is one of the given options that is the F₁ hybrid of tomato.
An F₁ tomato hybrid occurs when you have two tomato plants of different varieties and then one is pollinated by the other variety's pollen. The seeds of the resulting cross-pollinated tomato will grow plants that are F₁ hybrids. The children of F₁ hybrids are F₂.
Fruits of the Mangla variety are ready for picking after 65 days of transplanting and are medium having bright skin, and resistant to fusarium, verticillium and nematode.

The chemical commercially used for the prevention of sprouting in potatoes during storage is CIPC.
CIPC [Isopropyl N-(3-chlorophenyl) carbamate] is the most widespread and commonly used sprout suppressant on potatoes when stored at 8 - 12°C.
CIPC is primarily an herbicide that was introduced in the year 1951.
All of these chemicals are federally regulated and applied by licensed applicators. These preservatives are only applied to the skin of the potato and are washed off by the consumer before consumption.

Pectin is measured by Jelmeter.
A jelmeter is a graduated glass tube with an opening at each end. It is used to determine the amount of pectin in fruit juice. The content of pectin can be measured by calculating the weight of the precipitation.
It is an index of the amount of sugar to be used. The rate of flow of the juice through this tube is used as a measure of the jellying power of the juice.

Garlic contains the amino acid Alliin.
Alliin is a sulfoxide that is a natural constituent of fresh garlic. It is a derivative of the amino acid cysteine. When fresh garlic is chopped or crushed, the enzyme alliinase converts alliin into allicin, which is responsible for the aroma of fresh garlic.
Alliin showed a good hydroxyl radical-scavenging effect and has also been found to affect immune responses in blood.

First picking in bitter gourd can be done after 50 - 60 days.
The crop of bitter gourd takes about 55 - 60 days from seed sowing to reach the first harvest. Further pickings should be done at an interval of 2 - 3 days as bitter gourd fruits mature very fast and turn red. The yield is usually about 60 - 100 quintal/ha.
