摘要:

AbstractCultured sunflower cells reacted alike to inoculation in compatible and incompatible combinations with three races ofPlasmopara halstedii, cause of downy mildew. Infection structures formed on the surfaces of cells derived from both resistant and susceptible sunflowers, but no intracellular fungal structures or other signs of penetration were evident in either case. There was no indication of a hypersensitive reaction (rapid death) in cells within 20 h of inoculation in incompatible combinations. The reaction of cells in culture was not like that of intact plants in either compatible or incompatible combinations.

AbstractTelfairia mosaic virus (TeMV) was transmitted through seeds of four highly susceptible cultivars of fluted pumpkin (Telfairia occidentalisHook f.) in a screenhouse experiment.Infection was confirmed through visual appraisal and electron microscopy in cvs NHTo 75–10 (14), 54–4 (4), 54–4 (7), and 6–7 (14), to the extent of 20, 10, 6.4 and 6 % respe
