110R Anacına Aşılı Merlot Üzüm Çeşidi Genç Omcalarına Farklı Dozlarda Uygulanan Trichoderma harzianum ve Bacillus subtilis’ in II. Söküm Dönemindeki Etkileri

Bu araştırma 2014 yılında Namık Kemal Üniversitesi Ziraat Fakültesi Bahçe Bitkileri Bölümü Uygulama arazisinde, 2 yaşındaki Merlot/110R fidanları üzerine farklı dozlarda uygulanan Bacillus subtilis (0, %2, %4, %8) ve Trichoderma harzianum (0, 5g/L, 10g/L, 20g/L)’ un asma fidanlarının çap, kök ve sürgün gelişimi üzerine etkilerinin belirlenmesi amacıyla yapılmıştır. Her bir fidan 4 farklı dozda biyo-ajan (Sim Derma ve Sim Bacil) solüsyonuna 5dk süresince batırılıp bekletilmiştir. Araştırmada çap özellikleri, kök özellikleri ve sürgün özellikleri incelenmiştir. Bacillus subtilis; dip kök yaş ve kuru ağırlığı üzerine azaltıcı etkilerde bulunmuş, diğer kriterlerde ise artırıcı bir etki göstermiştir. Trichoderma harzianum ise ana sürgün çapı, yan kök yaş ağırlığı ve genel sürgün kuru ağırlığı üzerine azaltıcı etkiler yapmış; diğer kriterler üzerine ise pozitif bir etki yapmıştır. Sonuç olarak tüm biyo-ajanlar ve dozları incelendiğinde Bacillus subtilis’ in %8 ve Trichoderma harzianum 5g/L dozunun Merlot/110R fidanlarında söküm döneminde incelenen kriterler üzerine olumlu etkiler yaptığı belirlenmiştir. Bu nedenle araştırıcılar tarafından bundan sonra yapılacak olan çalışmalarda kullanılması önerilebilir.

Different Doses Effects of Trichoderma harzianum and Bacillus subtilis on Young plants 110R/Merlot II. Uprooting Period

This study was performed in 2014 at Namik Kemal University Agricultural Faculty Department of Horticulture Practices Area, in order to identify the effects of different doses Bacillus subtilis (0, 2%, 4%, 8%) and Trichoderma harzianum (0, 5g/L, 10g/L, 20g/L) on Merlot/110R two years old young plants. For this purpose, each young plants were dipped into 4 different doses of bio-agents (Sim Bacil and Sim Derma) solution for 5min before they were planted. In this research, diameter characteristics, root and shoot characteristics were evaluated. Bacillus subtilis decreased root fresh and dry weight whereas the other criterias unlike. Trichoderma harzianum decreased main shoot diameter, lateral root fresh weight and total shoot dry weight or positive effected the others. As a result, Bacillus subtilis dose 8% and Trichoderma harzianum dose 5g/L had a positive effect on Merlot/110R graft combination in uprooting period for examined characteristics. Therefore; it is suggested that these doses can be used for further studies.
