Which chemical is used for de-greening of fruit?
- A.
IBA
- B.
Cytokinin
- C.
Auxin
- D.
Gibberalic acid
- E.
Ethylene
Correct Answer
E. EthyleneExplanation
Ethylene is used for de-greening of fruit. Ethylene is a plant hormone that regulates various physiological processes, including fruit ripening. When applied to unripe fruit, ethylene promotes the breakdown of chlorophyll, which is responsible for the green color, resulting in the de-greening of the fruit. This process is commonly used in the fruit industry to accelerate the ripening of fruits such as bananas, tomatoes, and avocados.Rate this question:

- E.
NTA
Correct Answer
A. IAAExplanation
IAA, or Indole-3-acetic acid, is the most abundant and basic form of auxin. It is a naturally occurring plant hormone that plays a crucial role in various plant growth and development processes, such as cell elongation, root development, and fruit ripening. IAA is synthesized in the apical meristem of plants and is responsible for regulating plant growth and tropisms. It is also commonly used in laboratories and horticulture as a synthetic auxin to promote rooting and stimulate plant growth.Rate this question:

Which crop is called micronutrient loving crop
- A.
Apple
- B.
Banana
- C.
Papaya
- D.
Mango
- E.

Development of embryo without fertilization is known as _________
- A.
Parthenocarpy
- B.
Parthenogenesis
- C.
Apomixsis
- D.
Unfertility
- E.
None of these
Correct Answer

Parthenocarpy refers to the development of an embryo without fertilization. This process occurs in certain plants where the ovary develops into a fruit without the need for pollination or fertilization. Parthenocarpy can be induced artificially in some plants to produce seedless fruits, such as seedless grapes or bananas. Parthenogenesis, on the other hand, refers to the development of an embryo from an unfertilized egg, typically seen in some invertebrates and reptiles. Apomixis is a type of reproduction in plants where seeds are produced without fertilization, but it does not involve the development of an embryo. Therefore, the correct answer is Parthenocarpy.Rate this question:

Based on Salinity tolerance, Grapes is -
- A.
Highly tolerant
- B.
Moderately tolerant
- C.
Sensitive
- D.
Low tolerant
- E.
Proficly tolerant
Correct Answer
B. Moderately tolerantExplanation
Grapes are considered to be moderately tolerant to salinity. This means that they can withstand moderate levels of salt in the soil or water. While they may not thrive in highly saline conditions, they are able to tolerate a certain amount of salt without significant negative effects on their growth and productivity. Grapes have developed mechanisms to regulate water and ion uptake, which helps them cope with moderate salinity levels. However, excessive salinity can still have detrimental effects on grapevines, so it is important to manage irrigation and soil conditions carefully to ensure optimal growth and yield.Rate this question:
