[#666] Application of which chemical in the form of foliar spray at the beginning of flower bud development may improved drought resistance in pea
Correct Answer

(D) Chlormequat

Explanation

Solution: Application of Chlormequat chemical in the form of foliar spray at the beginning of flower bud development may improve drought resistance in pea. Chlormequat is an organic compound used as a plant growth regulator. Chlormequat has been called the most important inhibitor of gibberellin biosynthesis. It inhibits cell elongation, resulting in thicker stalks, which are sturdier, facilitating the harvesting of cereal crops. In exogenous application, it also improves drought resistance in some plants.

[#667] Tomato variety suitable to be grown under high temperatures is
Correct Answer

(B) Pusa hybrid-1

Explanation

Solution: The Tomato variety suitable to be grown under high temperatures is Pusa hybrid-1 . This hybrid of tomato is developed by IARI, New Delhi and is suitable for western India with hot summers (Fruit set up to 28°C) and Night temperatures 20°C normal. Fruits are round and flattish, thick pericarp, uniform ripening and smooth 2 - 3 locules. About 100 to 150 g of seeds are sufficient for raising seedlings for a hectare. It takes 120 to 130 days from transplanting to fruit ripening. It is highly tolerant to root-knot disease.

[#668] Curry leaf variety with red petiole variety is
Correct Answer

(D) Senkaambu

Explanation

Solution: Curry leaf variety with red petiole variety is Senkaambu . The curry tree, Murraya koenigii is a tropical to sub-tropical tree in the family Rutaceae and is native to Asia. The plant is also sometimes called sweet neem, though M. koenigii is in a different family to neem. It is a Coimbatore local type and the leaves have better aroma and flavour due to higher oil content. There are other two types of curry leaf viz., broad-leaved and small-leaved types. The small-leaved types are more fragrant and hence used for the extraction of essential oil.

[#669] Important factor affecting the condition to cut flowers during transportation is
Correct Answer

(D) Geotropism

Explanation

Solution: An important factor affecting the condition to cut flowers during the transportation is Geotropism . Geotropism is a growth response to gravity. Certain responses of cut flowers to environmental stimuli (tropisms) can result in quality loss. Most important is geotropism (bending away from gravity) and phototropism (bending toward the light). Geotropism often reduces quality in spike-flower crops like gladiolus, snapdragon, stock, roses and gerbera, because the flower stems (pedicels) or the main stem bends upward when stored horizontally. Geotropism is greatly reduced when flowers are maintained at low temperatures where this is not possible, such flowers should be handled upright.

[#670] Botanically, the fruit of litchi is a
Correct Answer

(A) Nut

Explanation

Solution: Botanically, the fruit of litchi is a Nut . Botanically litchi belongs to Sapindaceae family. The fruit is a one-seeded nut, develops in bunches, and varies in shape and size.
