Voorbeeldzinnen

1. Wilting
2. Observe for symptoms of wilting, epinasty, chlorosis and/or stunting.
3. Wilting symptoms are very different from those of brown rot; wilting is usually slow and initially limited to the leaf margins.
4. Observe for symptoms of wilting and/or epinasty, chlorosis and stunting.
5. With pure cultures typical wilting should be obtained within 14 days.
6. subsp. sepedonicus causes leaf wilting in eggplants which may commence as a marginal or interveinal flaccidity.
7. In early stages of wilting leaves remain green, but later yellowing and brown necrosis develops. Epinasty also occurs.
8. Bacteria may ooze from cut vascular tissues or form threads of slime if the cut stem is placed vertically in water, even in the absence of wilting symptoms.
9. Under less favourable conditions (soil temperature below 21 °C), less wilting occurs, but large numbers of adventitious roots may develop on the stem.
10. Grow the test plants in quarantine facilities for up to four weeks at 25 to 30 °C and high relative humidity with appropriate watering to prevent waterlogging or wilting through water deficiency.
11. Non-wilting S. dulcamara plants growing with stems and roots in water may show internal light brown discolouration of vascular tissues on transverse section of the stem base or underwater stem parts.
12. With pure cultures, typical wilting should be obtained within two weeks but plants not showing symptoms (see section 7.8) after this time should be incubated up to three weeks at temperatures conducive to eggplant growth but not exceeding 25 °C (Appendix 8).
13. Remove ooze or sections of discoloured tissue from the vascular ring in the potato tuber or from the vascular strands in stems of potato, tomato or other wilting host plants. Suspend in a small volume of sterile distilled water or 50mM phosphate buffer (Appendix 4) and leave for 5 to 10 minutes.
14. Incubate at 18 to 24 °C with sufficient light and high relative humidity with appropriate watering to avoid waterlogging or drought stress (section 7.7). With pure cultures, typical wilting should be obtained within two weeks but plants not showing symptoms (see section 7.8) after this time should be incubated up to three weeks at temperatures conducive to eggplant growth but not exceeding 25 °C (Appendix 8).
