Özet:

 The aim of the study is to determine the change in the viability rates of seeds by time and to determine the depth of emergence for the control of Ipomoea triloba IPOTR and Convolvulus arvensis CONAR, which are important weed species in the agricultural areas of the Mediterranean region. In order to determine the optimum emergence depth of CONAR and IPOTR seeds in the study, 25 weed seeds were placed at 2, 5, 10, 15 and 20 cm depths in pots with soil  peat  sand mixture in a climate chamber adjusted at 30 C. For the evaluation, the seedlings that emerged to the soil surface on the 7th, 14th, 21st and 28th days were counted, the emergenced seeds were taken out and the emergence rate percentage was calculated. In the study carried out to determine the life span of CONAR and IPOTR species in the soil; 10 and 20 cm deep pits were prepared for both weed species. 0.25 kg of sterilized soil and 300 pieces of seeds were placed in each bag to be buried in the ground. Seeds buried at 10 and 20 cm depths of the soil were used to conduct germination experiments to determine the viability of the seeds at 6, 12, 18, 24 and 30 months following the burial date. It was determined that the best emergence in the seeds of both species occurred at a depth of 2 cm and the emergence rate was 84.0 for CONAR and 96.8 for IPOTR. The longevity of CONAR seeds at 10 and 20 cm depths of the soil were determined as 90.10and 87.5 at the 6th month, and 15.40 and 9.50 at the 30th month. The longevity of IPOTR seeds at 10 and 20 cm depths of the soil were 93.90 and 85.20 at the 6th month, while it was determined as 10.10 and 7.60 at the 30th month, respectively. According to our study results, it is thought that seed germination can be reduced by deep tillage to control CONAR and IPOTR, and thus the density can also be reduced and new seed formation can be prevented. It is thought that among the methods of control CONAR and IPOTR, which are seen in many regions of our country and cause economic damage, it will be beneficial for the producers to determine the application method in this direction, where tillage can be used.

 Akdeniz Bölgesi tarım alanlarındaki önemli yabancı ot türlerinden olan Ipomoea triloba L. IPOTR ve Convolvulus arvensis L. CONARˈin mücadelesine yönelik olarak tohumların canlılık oranlarının zaman içerisindeki değişiminin belirlenmesi ve çıkış derinliklerinin saptanması çalışmanın amaçlarını oluşturmaktadır. Çalışmada CONAR ve IPOTR tohumlarının optimum çıkış derinliğinin belirlenmesi için, yabancı ot tohumları 30 Cˈye ayarlı iklim odasında, toprak torf kum karışımı bulunan saksılar içerisine 2, 5, 10, 15 ve 20 cm derinliklerine 25ˈşer adet konulmuştur. Değerlendirme için 7, 14, 21 ve 28. günlerde toprak yüzeyine çıkan bitkiler sayılmış, çıkış yapan tohumlar dışarı alınmış ve çıkış yüzdesi hesaplanmıştır. CONAR ve IPOTR türlerinin topraktaki yaşam sürelerinin belirlenmesi amacıyla yapılan çalışmada; her iki yabancı ot türü için 10 ve 20 cm derinlikte çukurlar hazırlanmıştır. Toprağa gömülen her torba içerisine 0.25 kg sterilize edilmiş toprağa 300ˈer adet tohum konulmuştur. Toprağın 10 ve 20 cm derinliğine gömülü tohumlar gömülme tarihini takip eden 6, 12, 18, 24, 30. aylarda tohumların canlılıklarının belirlenmesine yönelik çimlenme denemeleri yapmak üzere tohumlar kullanılmıştır. Her iki türün tohumlarında en iyi çıkışın 2 cm derinlikte gerçekleştiği ve çıkış oranının CONAR için 84.00, IPOTR için 96.80 oranında olduğu belirlenmiştir. CONAR tohumlarının topraktaki yaşam süreleri, toprağın 10 ve 20 cm derinliklerinde, sırasıyla 6. ayda 90.10 ve 87.50 olarak belirlenirken, 30. ayda 15.40 ve 9.50; IPOTRde ise 6. ayda 93.90 ve 85.20; 30. ayda 10.10 ve 7.60 olarak tespit edilmiştir. Çalışma sonuçlarına göre CONAR ve IPOTR ile mücadelede derin toprak işlemesi yapılarak tohum çimlenmesininçıkışının azaltılabileceği ve bu sayede yoğunluğun azaltılıp yeni tohum oluşumunun engellenebileceği değerlendirilmektedir. Ülkemizin pek çok bölgesinde görülen ve ekonomik zarara sebep olan CONAR ve IPOTR ile mücadele yöntemleri içerisinde, toprak işlemenin kullanılabileceği ve üreticilere fayda sağlayacağı düşünülmektedir.
