A field experiment was held in Hulu-dao, Liaoning Province, to assess the growth, yield, and fruit quality of Hanfu apples grafted on ten dwarfing interstocks.
The study found that tree vigor and fruit traits were significantly influenced by the type of interstock, with GM256 showing superior plant growth and fruit weight, while CX5 excelled in trunk diameter and root characteristics.
The evaluation ranked interstocks GM256 and CX5 as the most suitable for the cold climate, based on various performance metrics like fruit firmness and overall character scores.
