Investigation of the resistance of some citrus rootstocks against citrus nematode [Tylenchulus semipenetrans (Cobb, 1913) (Tylenchida: Tylenchulidae)] under field conditions in the Eastern Mediterranean Region

چکیده

Anaçlar, meyve verimi, kalitesi, abiyotik ve biyotik stres koşullarına karşı tolerans/direnç açısından turunçgil üreticiliğinde önemli bir rol oynamaktadır. Turunçgil üretimini sınırlandıran faktörlerden biri de Tylenchulus semipenetrans (Cobb, 1913) (Tylenchida, Tylenchulidae)’dır. Dayanıklı anaçlar, T. semipenetrans’ın mücadelesinde en iyi seçeneklerden birisi olmuştur. Bu çalışmada Adana ilinde nematodu ile doğal olarak bulaşık Çukurova Üniversitesi Koleksiyon parsellerinden, seçilen 54 anaçdan 2012-2016 yılları arasında toprak kök örnekleri alınmıştır. Toprak örneklerinden nematodlar, geliştirilmiş Baerman Huni yöntemi kullanılarak ekstrakte edilmiştir asit fuksinle boyanmıştır. Kök incelendiğinde 17 anaç çeşidin köklerinde rizosferdeki toprakta nematoduna çok az rastlanırken, Citrus aurantium L. (Rutaceae)’ye ait 37 anaçtan Tuzcu 31-25T, 31-30T 891 hariç diğerlerinde zararlı yoğun bulunmuştur. Anaç kökleri rizosferde bulunan nematodunun popülasyon yoğunluğuna göre, 31-25T orta hassas; 31-30T, Nasnaran, Poncirus trifoliata, Kleopatra ant, Local trifoliate, Cloex swingle, Citrumelo 4475, C-35, Gou tou, Sunki, 891, Carrizo citrange dayanıklı; diğer tüm anaçlar hassas tespit edilmiştir. Tüm nematod çoğalmasını desteklemiş ancak farklı duyarlılık seviyeleri göstermiştir.

Management of the Citrus Nematode, Tylenchulus semipenetrans.

Of the many nematode species that parasitize citrus, Tylenchulus semipenetrans is the most important on a worldwide basis. Management of the citrus nematode remains problematic as no one tactic gives adequate control of the nematode. An overall management strategy must include such components as site selection, use of non-infected nursery stock, use of at lease one post-plant nematode control t...

Characterization of Citrus Rootstock Responses to Tylenchulus semipenetrans (Cobb).

Citrus rootstocks which significantly limited the reproduction of Tylenchulus semipenetrans (Cobb) "Citrus" and "Poncirus" biotypes responded to infection by producing a hypersensitive-type response in the root hypodermis, wound periderm and/or cavities in the root cortex, and/or abnormal vacuoles in nurse cell cytoplasm. Rootstocks which limited nematode reproduction also had significantly few...

Tylenchulus semipenetrans Alters the Microbial Community in the Citrus Rhizosphere.

Infection of citrus seedlings by Tylenchulus semipenetrans was shown to reduce subsequent infection of roots by Phytophthora nicotianae and to increase plant growth compared to plants infected by only the fungus. Hypothetical mechanisms by which the nematode suppresses fungal development include nutrient competition, direct antibiosis, or alteration of the microbial community in the rhizosphere...

Seasonality of Tylenchulus semipenetrans Cobb and Pasteuria sp. in Citrus Orchards in Spain.

Population densities of the Mediterranean biotype of Tylenchulus semipenetrans were monitored in soil and citrus roots at 3-month intervals for 3 consecutive years in four citrus orchards in the provinces of Tarragona (Amposta and Xalamera) and Valencia (Moncada and Ca rcer). Nematode population densities in soil peaked once a year in April or July depending on the orchard and year. Numbers of ...

Parasitism of the Citrus Nematode, Tylenchulus semipenetrans, by Pasteuria penetrans in Iraq.

Pasteuria penetrans Sayre & Starr parasitizes several nematode species and is considered a promising biocontrol agent of the root-knot nematode, Meloidogyne spp. (1,7). Numerous plant-parasitic nematodes, including Tylenchulus semipenetrans, however, are seldom if ever infected by this biocontrol agent (3). Tylenchulus semipenetrans Cobb is the most economically important and widespread nematod...
