TY - JOUR A1 - Mandryk, M T1 - Resistance of Solanaceous and non-Solanaceous species to Peronospora tabacina as shown by necrotrophic reactions JF - Australian Journal of Experimental Agriculture JO - Aust. J. Exp. Agric. Y1 - 1971 VL - 11 IS - 48 SP - 94 EP - 98 KW - UR - https://doi.org/10.1071/EA9710094 N2 - A necrotrophic reaction in leaf discs of a wide range of Nicotiana and other Solanaceous and non-Solanaceous species following infection by Peronospora tabacina Adam is described.With a few exceptions, species resistant to the pathogen developed water-soaking or gave no reaction, whereas susceptible species showed necroses affecting 60-100% of the leaf disc area. The degree if necrotrophic reaction is related to the resistance-susceptibility status of Nicotiana species, and it may be extended to detect susceptibility to the pathogen in Petunia, Capsicum, Lycopersicon, Hyoscyamus, Schizanthus, and other genera related ti Nicotiana.
