Question:
Which of the following is based on sexual propagation?
Which of the following is based on sexual propagation?
Show Hint
Remember that a 'Stump' in forestry is not a tree base left in the ground; it is a prepared seedling with 1-2 inches of shoot and 9 inches of root used for planting.

- Cuttings
- Layering
- Tissue culture
- Stumps

Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Step 1: Understanding the Question:
Sexual propagation involves reproduction through seeds (the union of gametes), whereas asexual (vegetative) propagation uses plant parts like stems or leaves.
Step 2: Detailed Explanation:
• Cuttings (A) and Layering (B) are standard methods of vegetative propagation where a piece of a plant is induced to root.
• Tissue culture (C) is a laboratory-based vegetative propagation method using micro-explants.
• Stumps are a specific type of planting material prepared by cutting back the shoot and root of a 1-2 year old seedling.
• Since the seedlings themselves are grown from seeds (sexual reproduction), stumps are ultimately based on sexual propagation. They are commonly used for species like Teak.
Step 3: Final Answer:
Stumps are based on sexual propagation.

Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
