| 本研究以经热处理结合茎尖培养脱毒后，只携带灰比诺葡萄病毒（Grapevine Pinot gris virus，GPGV）或沙地葡萄茎痘病毒（Grapevine rupestris stem pitting associated virus，GRSPaV）、同时携带GPGV、GRSPaV和不带病毒的‘阳光玫瑰’葡萄1年生树为试材，探讨不同病毒对‘阳光玫瑰’葡萄生长和叶片营养元素含量的影响。结果表明，除节数外，带病毒试材的生长指标均显著低于脱毒苗。仅携带GRSPaV与仅携带GPGV的植株株高、节间长度无显著差异，但GRSPaV和GPGV复合感染后其株高与节间长度显著降低。仅带GRSPaV的茎显著细于只带GPGV的植株，GRSPaV和GPGV复合感染后茎更细。仅带GPGV、仅带GRSPaV的植株和带GRSPaV与GPGV这2种病毒的植株总根长、根平均直径、根体积、根干鲜重显著低于脱毒苗，三者间无显著差异。携带单一病毒GPGV或GRSPaV、携带GRSPaV和GPGV的植株叶片Ca、Mn的含量较无病毒植株显著降低。仅携带GPGV的植株不显症叶片Ca、Mn含量显著高于仅携带GRSPaV；感病植株的显症叶片及不显症叶片K、Zn、B的含量较脱毒苗显著升高，仅携带GPGV的植株不显症叶片K含量显著高于仅携带GRSPaV植株，Zn和B含量无显著差异；感病植株显症叶片中Mg、Fe、Cu的含量高于脱毒苗，而在不显症叶片中其含量低于脱毒苗，携带GPGV植株的不显症叶片Mg、Fe含量显著低于携带GRSPaV植株，B含量无显著差异。综上表明，单一GPGV或GRSPaV通过影响营养元素的含量而抑制植株地上部和根系生长，且这两种病毒复合感染后对植株影响加重。 |

| After heat treatment combined with stem tip culture detoxification, this study used one-year-old ‘Shine Muscat’ grape trees carrying either the Grapevine Pinot gris virus (GPGV) or the Grapevine rupestris stem pitting associated virus (GRSPaV) or both as test materials to investigate the effects of different viruses on the growth and leaf nutrient content of ‘Shine Muscat’ grapes. The results showed the growth indicators of the virus-containing test materials were significantly lower than those of the detoxified seedlings, with the exception of the number of nodes. There was no significant difference in plant height and internode length between plants carrying only GRSPaV and only GPGV. However, the plant height and internode length were significantly reduced after the combined infection of GRSPaV and GPGV. The stems of GRSPaV-only were significantly thinner than those of GPGV-only, and the stems were even thinner after GRSPaV and GPGV co-infection. Total root length, mean root diameter, root volume, and root dry weight and fresh weight were not significantly different among plants with GPGV only, GRSPaV only, and plants with both GRSPaV and GPGV, but were significantly lower than those of detoxified seedlings. Leaf Ca and Mn contents were significantly lower in plants carrying a single virus, GPGV or GRSPaV, and in plants carrying GRSPaV and GPGV, compared with virus-free plants. The contents of Ca and Mn in the asymptomatic leaves of plants carrying only GPGV were significantly higher than those of plants carrying only GRSPaV; the contents of K, Zn, and B in the symptomatic and asymptomatic leaves of susceptible plants were significantly higher than those of detoxified seedlings; the contents of K in the asymptomatic leaves of plants carrying only GPGV were significantly higher than those of plants carrying only GRSPaV, and there was no significant difference in the contents of Zn and B. The contents of Mg and Fe in the symptomatic leaves of plants carrying virus were higher than those of detoxified seedlings, The contents of Mg, Fe, and Cu in the symptomatic leaves of plants carrying virus were higher than those of detoxified seedlings , but they were lower than those of detoxified seedlings. The contents of Mg and Fe in the non-symptomatic leaves of GPGV-carrying plants were significantly lower than that of GRSPaV-carrying plants, and there was no significant difference in B content. In conclusion, it was shown that a single GPGV or GRSPaV inhibited plant aboveground and root growth by affecting the content of nutrient elements, and that the effects on plants were exacerbated by a compound infection of these two viruses. |
