Özet

In this study, an investigation was conducted to assess the susceptibility and resistance of various citrus rootstocks and scions to four distinct bot canker pathogens: Diploida seriata, Neofusicoccum parvum, Lasiodiplodia pseudotheobromae, and L. theobromae. Findings revealed that the cultivars ‘Fukumoto’ and ‘Cara Cara’ were found to exhibit the highest degree of sensitivity to all four pathogens. In contrast, the C35 rootstock, a Carrizo hybrid, was observed to be resistant to Diplodia seriata and N. parvum, with a moderate resistance observed toward L. pseudotheobromae and L. theobromae, as evidenced by the minimal necrosis observed in stem cuttings. Significant sensitivity to N. parvum was exhibited by ‘Okitsu Wase’, leading to pronounced necrosis on stem cuttings, while displaying resistance to D. seriata with minimal necrosis formation. ‘Navelina’ orange, on the other hand, was found to display a uniform susceptibility to all four pathogen infections, characterized by severe necrosis. ‘Dobashi Beni’ was found to be susceptible to N. parvum and L. theobromae pathogens while displaying resistance to D. seriata and L. pseudotheobromae. ‘Meyer’ lemon was observed to demonstrate resistance to D. seriata, L. pseudotheobromae, and L. theobromae pathogens, with slight necrosis observed in response to N. parvum, indicating a moderate level of resistance. Resistance to D. seriata and L. theobromae pathogens was exhibited by ‘Interdonato’ lemon, with a moderate resistance observed to N. parvum and L. pseudotheobromae. ‘Kutdiken’ lemon was found to demonstrate potential resistance to N. parvum, although susceptibility to Lasiodiplodia spp. was noted. This study represents a preliminary assessment of various commercial citrus species and cultivars regarding their responses to bot canker pathogens in Turkey.
