两个生长季节的试验清楚地表明，芜菁花叶病毒（TuMV）感染与内部坏死（直径5 - 10 mm的凹陷坏死点）有关，甜菜西部黄化病毒（BWYV）感染与储存的白色甘蓝（Brassica oleracea var. capitata）。在cv中几乎没有观察到尖端灼伤。Polinius，而CV。黑斑羚受到严重影响。两个品种均出现内部坏死斑。BWYV似乎与TuMV相互作用。两种病毒感染的植物表现出较低的发病率的外部症状，并有较少的内部坏死比TuMV单独感染的植物，CaMV花花叶病毒（CaMV）没有引起显着量的内部坏死或尖烧。但在大多数情况下，会加重TuMV和BWYV引起的症状。BWYV诱导的尖烧在储存过程中显着恶化。移植后接种TuMV诱导更多的内部坏死比移植前接种。在收获前检测到TuMV与随后的内部坏死点的发展之间存在显著相关性。单独来看，这三种病毒都显著降低了cv的产量。而只有BWYV和CaMV处理降低了cv.黑斑羚
Experiments over two growing seasons clearly showed that Turnip mosaic virus (TuMV) infection was associated with internal necrosis (sunken necrotic spots 5 to 10 mm in diameter) and Beet western yellows virus (BWYV) infection was associated with collapse of leaf tissue at the margins (tipburn) in heads of stored white cabbage (Brassica oleracea var. capitata). Virtually no tipburn was seen in cv. Polinius, whereas cv. Impala was affected severely. Internal necrotic spots were seen in both cultivars. BWYV appeared to interact with TuMV. Plants infected with both viruses showed a lower incidence of external symptoms and had less internal necrosis than plants infected with TuMV alone, CaMV flower mosaic virus (CaMV) did not induce significant amounts of internal necrosis or tipburn. but did, in most cases, exacerbate symptoms caused by TuMV and BWYV. BWYV-induced tipburn worsened significantly during storage. Post-transplanting inoculation with TuMV induced more internal necrosis than pre-transplant inoculation. There was a significant association between detection of TuMV just prior to harvest and subsequent development of internal necrotic spot.. Individually, all three viruses significantly reduced the yield of cv. Polinius, whereas only BWYV and CaMV treatments reduced the yield of cv. Impala.
