Abstract

This study was conducted to determine the effects of different plant growth promoting rhizobacteria (PGPR) strains on growth and quality of broccoli seedlings. The strains of B. megaterium TV-3D, B. megaterium TV-91C, P. agglomerans RK- 92 and B. megaterium KBA-10 were used in this study. The suspension of bacteria was applied twice into root zone with one-week interval after germination of seeds. The results of the study showed that PGPR treatments increased seedling length, stem diameter, leaf area, and leaf dry matter at ratios of 7.85 %, 42.56 %, 18.12 % and 41.98 %, respectively, compared to the control. Except for Na, the mineral element content was also increased with PGPR treatments. Amino acids in broccoli seedlings were significantly affected with PGPR applications (except for theonine, methionine, phenylalanine and hydoxyproline). Furthermore, organic acids of seedlings were increased with PGPR applications. The highest gibberallik acid (GA), salicylic acid (SA) and abscisic acid (ABA) contents were obtained from P. agglomerans RK-92 application. As a result, B. megaterium TV-3D, B. megaterium TV-91C, P. agglomerans RK-92 and B. megaterium KBA-10 applications improved growth and quality of broccoli seedlings by affecting mineral element, amino acid, organic acid and hormone contents.

Özet

Araştırma bitki gelişimini teşvik eden rizobakterilerin (Plant Growth Promoting Rhizobacteria-PGPR) brokkolide (Brassica oleracea L. var. italica) fide gelişimi ve fide kalitesi üzerine etkilerinin belirlenmesi amacıyla yapılmıştır. Çalışmada, Bacillus megaterium TV-3D, Bacillus megaterium TV-91C, Pantoea agglomerans RK- 92 ve Bacillus megaterium KBA-10 bakteri ırkları kullanılmıştır. Uygulamalar brokkoli fidelerine tohum çimlenmesinden sonra süspansiyon şeklinde birer hafta aralıklarla iki kez olacak şekilde yapılmıştır. Araştırmada, PGPR uygulamalarının kontrol uygulamasına göre fide boyunu % 7.85, gövde çapını % 42.56, yaprak alanını % 18.12 yaprak kuru madde miktarını ise % 41.98 oranlarına kadar artırdığı saptanmıştır. Çalışmada, PGPR uygulamalarının fide besin elementi içeriğini Na hariç artırdığı belirlenmiştir. PGPR uygulamalarının brokkoli fidelerinde aminoasit içerikleri üzerine etkileri istatistiksel olarak önemli (treonin, methionin, fenilanin ve hidroksiprolin hariç) bulunmuştur. Fide organik asit içerikleri ise PGPR uygulamalar ile genellikle önemli bir artış göstermiştir. En yüksek giberallik asit (GA), salisilik asit (SA) ve absisik asit (ABA) içeriği P. agglomerans RK-92 uygulamasından elde edilmiştir. Araştırma sonucunda kullanılan PGPR uygulamalarının brokkoli fidelerinde mineral madde, aminoasit, organik asit ve hormon içeriklerini etkileyerek fide gelişimi ve kalitesini olumlu etkilediği belirlenmiştir.
