对感染混合潜隐性病毒的富士、金冠苹果树进行了生理生化及生长结果指标检测，结果发现，与品种脱毒树相比，在生理生化方面：病毒树内含物质ＧＡ３、ＣＴＫ、ＩＡＡ、ＲＮＡ 和蛋白质含量降低，ＤＮＡ含量升高；总光合强度及净光合强度下降，呼吸强度升高。在生长结果方面：病毒树的树高、干径、冠径和一年生枝长度减弱，坐果率和产量降低；果实可溶性固形物、总糖、还原糖及Ｃａ、Ｆｅ、Ｍｎ 含量下降，果肉硬度降低
Physiological and biochemical indexes and growth indexes of Fuji and Golden Delicious apple trees infected with mixed latent virus were detected. The results showed that in terms of physiological and biochemical aspects, the contents of GA3, CTK, IAA, RNA and protein content decreased, DNA content increased; total photosynthetic and net photosynthetic intensity decreased, respiratory intensity increased. In the aspect of growth results, the tree height, stem diameter, crown diameter and annual branch length of the virus tree were weakened, and the fruit setting rate and yield were decreased. The contents of soluble solids, total sugar, reducing sugar, Ca, Fe and Mn decreased,
