Question:
The rootstock that imparts dwarfness to plants is
The rootstock that imparts dwarfness to plants is
Show Hint
Remember rootstock types:
- Dwarfing: Reduces plant size (M9, M26 for apple)
- Semi-dwarfing: Moderate size (MM106 for apple)
- Vigorous: Large trees (seedling rootstocks)
- Clonal: True to type propagation
Dwarfing rootstocks are used for high-density planting.

The Correct Option is C
Solution and Explanation
Step 1: Understanding the Concept:
This question tests knowledge of rootstocks and their effects on plant growth.
Step 2: Detailed Explanation:
Dwarfing rootstock is specifically used to impart dwarfness to plants.
These rootstocks:
- Reduce the overall size of the plant.
- Induce early flowering and fruiting.
- Increase planting density.
- Facilitate easy management and harvesting.
Examples:
- Apple: Malling 9 (M9) - dwarfing rootstock.
- Pear: Quince C - dwarfing rootstock.
- Peach: Prunus besseyi - dwarfing rootstock.
Other rootstock types:
- Seedling rootstock (A): Gives standard-sized trees, variable.
- Clonal rootstock (B): Can be dwarfing, semi-dwarfing, or vigorous depending on the clone.
- Vigorous rootstock (D): Produces large trees, late fruiting.
Thus, dwarfing rootstock imparts dwarfness to plants.
Step 3: Final Answer:
Thus, the rootstock that imparts dwarfness is dwarfing rootstock, which corresponds to option (C).
