| 中文摘要: |
| 经调查确认,康乃馨锈病在新疆的侵染源主要是来自于产地的夏孢子随着康乃馨种苗远距离传播而至。对病原的初步研究表明,适宜本菌夏孢子萌发和生长的温度范围很广,耐低温性强,在乌鲁木齐冬季一定的环境条件下,完全可以以夏孢子菌态安全的越冬,为翌年再侵染提供出巨量持活性的初次侵染源。文中并讨论了治理康乃馨锈病的策略与措施。 |
| 英文摘要: |
| The major infective source of carnation rust in Xinjiang was found to be transmission of the pathogen uredosorus on young carnations when they are moved from place to place.With continuous observations on the signs and morphological research on its pathogen,It was found that the previous documents in the literature were far from perfection.Therefore,it is suggested that further work be done.Preliminary examinations on the pathogen showed that the temperature range that is suitable for the uredospores to germinate and grow is quite broad and the uredospores were persistent at very low temperature.In a typical farming environment in Urumqi,the disease can easily overwinter in the form of uredosorus with either sealed or slightly open pustules,which leaves a continuous primary infective source in the following planting season.It was also discussed the measurement and strategy that might be used to treat carnation rust. |
