无病毒与带病毒苹果树的内含物及生长结果习性比较研究

STUDIES ON INTERNAL SUBSTANTAILS AND GROWING FRUITING HABITS OF VIRUS—FREE AND VIRUS INFECTED APPLE TREES

本试验对无病毒和带病毒富士、金冠苹果树的内含物及生长、结果、产量等指标进行了测定。结果表明,无病毒树的内源激素、核酸、蛋白质含量均高于带病毒树的含量;无病毒树较带病毒树生长强,分枝多,成花易,早期产量高;但二者的果实营养成分含量无明显差异。

The hormores, nucleic acids, proteins, growing, fruiting and yield of virus-free and virus-infected Fuji, Golden Delicious were tested in this experiment.The results sbowed that the contents of hormores nucleic acids and proteins of the virus-free apple trees were higher than the virusinfected ones. The virus-free trees grew stronger and had more branches, flowers and early yields. But there was no significant difference in nutrients of fruits between them.
