Abstract:
Taking Shandingzi as the base stock and SH1，Y-1，B9，T337，M26 as the intermediate anvils to graft ‘Yanfu 3’，the morphology，anatomical structure，antioxidant enzyme active substances and fruit quality of apple leaves were determined，the effects of five dwarfing intermediate anvils on leaf physiology and fruit quality of ‘Yanfu 3’ apple were studied，so as to provide theoretical basis for breeding rootstock-spike combinations suitable for dwarfing close planting of apple and high quality and high yield of fruit in Longdong region.The results showed that the leaf length and leaf area of Y-1 and T337 were reduced compared with SH1，B9 and M26，while the fresh weight，dry weight and dry-fresh ratio of louvers were significantly increased.The palisade tissue thickness and sponge tissue thickness of Y-1 and T337 were significantly higher than those of other combinations，while the stomatal density，leaf tissue compactness and porosity were significantly lower than those of other anvil-spike combinations.SOD，POD activities of Y-1 and T337 were higher than those of SH1，B9 and M26，while MDA content was significantly decreased，which indicated that Y-1 and T337 rootstock-spike combinations were superior to SH1，B9 and M26 in leaf maturation ability.The fruit comprehensive quality of Y-1 and T337 were significantly higher than those of other rootstock-spike combinations.Comprehensive results showed that Y-1 and T337 rootstock-spike combinations were superior to other rootstock-spike combinations in leaf internal quality，physiological nutrition level and fruit quality.
