Callose in rootstock stem when scion was inoculated with SMV. A Non-inoculated upper leave of the rootstock; B Scion leaves inoculated with SMV; C Callose fluorescence was detected in stem of rootstock below the grafting site at 3-days after scion nf58 was frictionally inoculated with N3; D micrograph of C under transmission light; E Callose fluorescence was not detected in stem of rootstock above the grafting site at 3 days after scion nf58 was frictionally inoculated with N3; F micrograph of E under transmission light; G Callose fluorescence was not detected in stem base of the rootstock Wuxing 2 at 3-days after scion Jihuang 13 was frictionally inoculated with SC-8; H micrograph of (G) under transmission light; c, e, and g: the enlarged pictures of the areas labeled with arrows in picture C, E, and G
