Özet:

 In this study, it was carried out to determine the effects of different bacterial strains Brevibacillus parabrevis strain SB29, Herbaspirillum huttiense strain SK4 ve Virgibacillus pantothenticus strain YÖ19 on the germination of curly lettuce seeds and the development of lettuce plants and to investigate some of their mechanisms of action. In the in vitro test, it was determined that bacterial applications increased the germination rate and germination rate of seeds. The effect of bacterial applications on the growth parameters of the lettuce plant was investigated with 6 applications SB29, SK4, YÖ19, SB29 SK4 YÖ19, chemical fertilizer and control according to the randomized blocks experimental design. It was found that all of the applications gave better results than fertilizer application in terms of root dry matter ratio, leaf number and plant dry weight in lettuce, but their effects on leaf dry matter were insignificant. It was observed that the treatments compared to the control were effective on plant weight, plant diameter, plant height, stem diameter, root dry weight and crude protein ratio. It was determined that all strains produced IAA and were catalase positive. Siderophore production was detected in Strain YÖ19 and SK4, while three strains were found to be ACC deaminase negative. It was concluded that IAA production, nitrogen fixation and phosphate solubility properties of the strains were effective in the germination of lettuce seeds.

 Bu çalışma farklı bakteri strainlerinin Brevibacillus parabrevis strain SB29, Herbaspirillum huttiense strain SK4 ve Virgibacillus pantothenticus strain YÖ19 kıvırcık marul tohumunun çimlenmesine, marul bitkisinin gelişimine etkisini belirlemek ve bazı etki mekanizmalarını araştırmak amacıyla yapılmıştır. In vitro testte bakteri uygulamalarının tohumların çimlenme hızını ve çimlenme oranını arttırdığı tespit edilmiştir. Marul bitkisinin gelişme parametrelerine bakteri uygulamalarının etkisi tesadüf blokları deneme desenine göre 6 uygulama SB29, SK4, YÖ19, SB29 SK4 YÖ19, kimyasal gübre ve kontrol ile araştırılmıştır. Uygulamalarının hepsinin marulda kök kuru madde oranı, yaprak sayısı ve bitki kuru ağırlığı bakımından gübre uygulamasından daha iyi sonuç verdiği, yaprak kuru madde üzerine etkilerinin ise önemsiz olduğu bulunmuştur. Bitki ağırlığı, bitki çapı, bitki boyu, gövde çapı, kök kuru ağırlığı ve ham protein oranı üzerinde kontrole göre uygulamaların etkili olduğu görülmüştür. Strainlerin hepsinin IAA ürettiği ve katalaz pozitif olduğu belirlenmiştir. Strain YÖ19 ve SK4de siderofor üretimi tespit edilirken üç strainin ACC deaminaz negatif olduğu saptanmıştır. Marul tohumlarının çimlenmesinde strainlerin IAA üretmelerinin, azot fikse edebilmelerinin ve fosfat çözebilme özelliklerinin etkili olduğu sonucuna varılmıştır.
