Key Advantages
-
High-Density Efficiency: Supports planting densities of 80-120 trees per mu (equivalent to 533-800 trees per acre; vigorous rootstocks allow only 30-50 trees per mu), significantly reducing pruning and harvesting costs.
-
Early Fruiting & Superior Quality: Trees bear fruit within 2-3 years after grafting (1-2 years earlier than vigorous rootstocks), producing larger fruit with higher sugar content.
-
Enhanced Stress Tolerance: Selected varieties improve adaptability to environmental stresses such as drought and cold damage.
Characteristics of Major Varieties
-
Gisela 5: Extreme dwarfing (40-50% of standard tree height). Fruits in the 2nd year. Requires diligent drought and lodging prevention management.
-
Gisela 6: Semi-dwarfing (60-70% of standard height). Outstanding cold and drought tolerance. Widely adapted globally.
-
ZY-1: Moderately dwarfing (50-60% of standard height). Strong early-fruiting trait. Tolerant to waterlogging and resistant to crown gall disease. Suitable for high-rainfall regions south of the Yellow River basin.
-
Mahaleb CDR-1: Semi-dwarfing. Excellent cold hardiness (-25°C) and tolerance to poor soils. Ideal for cold northern zones and mountainous cultivation.
Selection Guidelines
-
Climate Adaptation: Opt for Gisela 6 or Mahaleb in cold northern regions; choose Gisela 12 or ZY-1 in rainy southern areas.
-
Scion Compatibility: Prioritize Gisela 6 or ZY-1 when grafting sweet cherry cultivars.
-
Management Requirements: Select high-stress-tolerant varieties (e.g., Gisela 6, Mahaleb) for low-input cultivation systems.
Conclusion
Dwarfing rootstocks are paramount for achieving high-quality, high-yield cherry production. Precise variety selection—integrating regional climate, scion characteristics, and management capacity—is essential to maximize cultivation benefits.
