Abstract

The aims of this study were to determine the distribution of root-knot nematodes (Meloidogyne spp.) in kiwifruit orchards in Samsun Province (Türkiye) and assess the effect of Meloidogyne spp. on fruit yields in naturally infested orchards. The survey was conducted in 25 kiwifruit orchards in September-November 2017. In addition, the data on fruit yields was obtained in two orchards at the harvest time in 2018. Fifty-six soil and root samples were collected from infested orchards. Species identification was performed by esterase phenotype and PCR with species-specific primers. Meloidogyne spp. were found in 92% of the orchards surveyed. Meloidogyne luci (Carneiro et al., 2014) (Tylenchida: Meloidogynidae) was detected in 59% of the samples, followed by Meloidogyne hapla (Chitwood, 1949) in 41%, Meloidogyne arenaria (Neal, 1889) in 27% and Meloidogyne incognita (Kofoid & White, 1919) in 2%. Regarding the distribution of Meloidogyne spp. in kiwifruit orchards, M. luci was found in 74%, M. hapla in 57%, M. arenaria in 39% and M. incognita in 4% of orchards infested. Meloidogyne luci was found for the first time in the kiwifruit orchards of Türkiye in this study. It was also determined that Meloidogyne spp. caused significant yield losses in kiwifruit orchards, and yield losses of 36 and 49% were detected in two orchards infested with Meloidogyne spp., respectively.

Özet

Bu çalışmanın amacı, Samsun İli (Türkiye) kivi bahçelerinde kök-ur nematodlarının (Meloidogyne spp.) dağılımının belirlenmesi ve doğal olarak bulaşık bahçelerde meyve verimi üzerine Meloidogyne spp.’nin etkisinin değerlendirilmesidir. Sürvey 2017 yılı Eylül-Kasım aylarında 25 kivi bahçesinde yürütülmüştür. Ayrıca, 2018 yılı hasat zamanında iki bahçede meyve verimlerine ilişkin veriler elde edilmiştir. Bulaşık bahçelerden 56 toprak ve kök örneği alınmıştır. Tür teşhisleri esteraz fenotipi ve türe özgü primerler ile yapılan PCR ile gerçekleştirilmiştir. Meloidogyne spp., sürvey yapılan bahçelerin %92’sinde bulunmuştur. Örneklerin %59'unda Meloidogyne luci (Carneiro et al., 2014) (Tylenchida: Meloidogynidae) tespit edilmiş, bunu %41 ile Meloidogyne hapla (Chitwood, 1949), %27 ile Meloidogyne arenaria (Neal, 1889) ve %2 ile Meloidogyne incognita (Kofoid & White, 1919) izlemiştir. Meloidogyne spp.’nin kivi bahçelerindeki dağılımı ile ilgili olarak, bulaşık bahçelerin %74'ünde M. luci, %57'sinde M. hapla, %39'unda M. arenaria ve %4'ünde M. incognita bulunmuştur. Meloidogyne luci, Türkiye'deki kivi bahçelerinde ilk kez bu çalışmada bulunmuştur. Ayrıca, Meloidogyne spp.’nin kivi bahçelerinde önemli verim kayıplarına neden olduğu ve Meloidogyne spp. ile bulaşık iki bahçede sırasıyla %36 ve %49 verim kaybı olduğu belirlenmiştir.
