中文摘要 | 從田間菸草上所採得之136個CMV分離株中,選取5個(在菸草上引起不同病徵者)以探討比較在22種(包括9個科)不同植物品種上所產生之反應。本試驗係在溫室內完成,室內溫度之變異範圍為15°~32℃。 5 CMV系統在豇豆、蠶豆、西瓜、藜以及芝麻之接種葉上均引起局部病斑。黃斑系一號和二號在供試之茄科植物上均產生黃色崁紋及葉形變異。黃斑系一號在供試之荳科植物上均引起全身感染。黃斑系二號在百日草和千日紅之接種葉上能引起局部病斑,故甚易加以認別。輕症系在各種菸草植物上均引起輕微之崁紋。普通系在菸草以及其他鑑別寄主上所產生病徵和典型之CMV系統最為相似。劇變系在菸草及Nicotiana glutinsa L. 等植物上均引起劇烈之葉形變異。 |
英文摘要 | From 136 isolates of the cucumber mosaic virus (CMV) collected from the field grown tobacco plants, five (differing in symptoms produced on tobacco) were selected for studies on the host reaction in 22 plant species including nine families. Observations were made in the greenhouse with a temperature fluctuating between 15° and 32℃. All five isolates of CMV, considered to represent 5 strains induced local lesions on the inoculated leaves of cowpea, broadbean, watermelon, Chenopodium album L., and Seasmum indicum L. Both strain Y1 and Y2 produced yellow mottle and leaf distortion on the solanaceous plants tested. Strain Y1 caused systemic infection on all legumes tested. Strain Y2 was easily recognized by its ability to produce local lesions on the inoculated leaves of zinnia and Gomphrena globosa L. Strain C caused mild green mottle on various tobacco plants. Strain O most closely resembled the typical CMV in its symptoms on tobacco and other differential hosts. Strain SD developed more severe leaf distortion on tobacco and Nicotiana glutinosa L. |
