If you take the scion of desi mango and stock of dasheri mango, what type of mango will be produced?

  1. Desheri

  2. Desi

  3. Hybrid

  4. None
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The grafted branches present will give rise to dasheri mangoes whereas the rest of the branches will give rise to desi mangoes.

So, the correct option is 'Desi'.

In grafting process 

  1. Desirable characters of stock are transferred to scion

  2. Desirable characters of scion are transferred to stock.

  3. Desirable characters of both stock & scion are transferred to new bud

  4. Character transfer is not possible.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation
Grafting is a horticultural technique used to join parts from two or more plants so that they appear to grow as a single plant. In grafting, the upper part (scion) of one plant grows on the root system (rootstock) of another plant. 
In this process, desirable characters of scion are transferred to stock because the stock being root system cannot be uprooted as it decreases the survival rate.
So, the correct option is 'Desirable characters of scion are transferred to stock'.

The vegetative own in the where a branch is injured defoliated and pegged down in the ground is known as

  1. Layering

  2. grafting

  3. cutting

  4. bud grafting
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
In this method, the lower branch of the stem is bent down and partially defoliated. An injury is made in the defoliated portion. The injured and defoliated portion is covered with a light layer of moist soil in such a way that the growing tip of the branch remains above the soil surface. After a few days, the pegged portion develops adventitious roots. The rooted branch is then cut, separated from the parent plant and grown into a new plant. Examples - Jasmine, Grapevine, Strawberry, Raspberry, Cherry, etc.
So the correct option is 'Layering'.

In grafting the rooted plant is used as a ______.

  1. Scion

  2. Stock

  3. Stem

  4. Root
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

In grafting, two firmly related plants are utilized to deliver another plant that has the ideal, consolidated attributes of both the parent plants. One plant is the stock, where the root system is taken and where the shoot system is used is called the Scion,

So, the correct option is 'Stock'.

In vegetative reproduction, when two different individuals participate then it is called, _________?

  1. Layering

  2. Grafting

  3. Cutting

  4. Doubling
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

  • In grafting, two firmly related plants are utilized to deliver another plant that has the ideal, consolidated attributes of both the parent plants. One plant is, 
  • where the root framework is taken and the other is, where the shooting framework is utilized. The scion is appended to the load of the second plant in this strategy for fake vegetative proliferation. grafting can be done in plants like roses, apples, and avocado.

So, the correct option is 'Grafting'.

The part of the plant where metabolism takes place is

  1. Aerial

  2. Sub-aerial

  3. Underground

  4. All the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Plant metabolism involves the complex of physical and chemical events of photosynthesis, respiration, and the synthesis and degradation of organic compounds. These processes are seen to occur in the aerial parts of the plant. So, the correct option is 'Aerial'.

Which of the following defines phytotron?

  1. Fish culture facility

  2. Plant hormone

  3. Secondary metabolite

  4. Controlled plant culture facility
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A phytotron is an enclosed research greenhouse used for studying interactions between plants and the environment. It was a product of the disciplines of plant physiology and botany. The first phytotron was built under the direction of Frits Warmolt Went at the California institute of Technology in 1949. It was funded by the Harry B. Earhart Foundation and was officially known as the Earhart plant research Laboratory.

Roses and banana are usually grown through ...............

  1. Parthenocarpy

  2. Cuttings

  3. Grafting

  4. Layering
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Plants can reproduce asexually and sexually. The vegetative reproduction is a means of rapid propagation, as sex cells are not involved, the progeny is identical to parent plant and the process is a type of asexual reproduction. Vegetative reproduction can be natural or artificial (cutting, layering, grafting or use of stocks). Cutting is commonly used artificial method of vegetative propagation. In cutting a cut portion of a plant generates a whole new plant as in Rose, Bougainvillea, Banana etc. Banana is a large perennial herb propagated vegetatively rather than sexually because nearly all cultivated varieties are seedless, and fruits develop parthenocarpically (in the absence of seed development). The principal method of banana propagation is division of suckers or pups which arise from the base of the main stem or from the underground corm. Large suckers are the preferred planting material. These are removed from vigorous clumps of banana trees with a spade when at least three feet tall, during warm months.
