一种病毒从苹果树传至烟草和藜属植物。回到一系列木质指标，其中它只影响弗吉尼亚蟹;症状是木质部的凹槽，以及接穗与砧木结合处上方的肿胀和坏死。该病毒与引起弗吉尼亚蟹茎痘的病毒不同，因为虽然在几个苹果品种中很容易检测到，但在许多感染茎痘病毒的树木中没有发现。茎沟病毒具有600-700 m/μ长的弯曲颗粒，热灭活点为67 °C，稀释终点为10 - 3 inN。在20 °C下保持感染性至少2天。
A virus was transmitted from apple trees toNicotiana glutinosaandChenopodiumspp. and back to a range of woody indicators in which it affected only Virginia Crab; symptoms were grooves in the xylem, and swelling and necrosis of the scion immediately above the union with the stock. The virus was distinct from that causing stem pitting in Virginia Crab, because although easily detectable in several apple varieties, it was not found in many trees infected with stem pitting virus.The stem grooving virus has flexous particles 600–700 m/μ long, a heat inactivation point of 67 °C, a dilution end‐point of 10‐3inN. glutinosasap and remains infective for at least 2 days at 20 °C.
