MISIR BİTKİSİNDE BİTKİ GELİŞMESİNİ TEŞVİK EDEN VE ENGELLEYEN BAKTERİLERİN SERADA RİZOSFER BAKTERİLERİ KULLANILARAK ORTAYA ÇIKARILMALARI

Mısır rizosferinden elde edilen 576 bakteri izolatı bitki büyümesini teşvik edici ve zararlı etkileri yönünden serada iki patojenin de bulunduğu topraklarda test edilmiştir. Seçilen izolatlar serada tekrar test edilmiştir. Çoğunlukla bakteri izolatları mısır bitkisinin boyu üzerinde istatistiki bakımdan önemli bir etki göstermemişlerdir. Bitki boyu ile ilgili izolat etkileri tutarsızlık göstermiştir. Tohumların bakteriyle inokulasyonu sonucu mısır bitki boyunda görülen yararlı veya zararlı etkiler başka topraklarda veya denemelerde genellikle tekrar edilememiştir.

Anahtar Kelimeler:

Mısır; bakteri izolatı; bitki boyu

GREENHOUSE SCREENING OF RHIZOSPHERE BACTERIA FOR PLANT GROWTH PROMOTING RHIZOBACTERIA AND DELETERIOUS RHIZOBACTERIA OF MAIZE

A total of 576 bacterial isolates from the maize rhizosphere were tested in greenhouse experiments for growth promoting and deleterious activity towards maize seedlings in the presence of two pathogens. Selected isolates were further tested in the greenhouse. In most instances, the bacterial isolates had no statistically significant effect on maize plant height. Isolate effects on plant height were inconsistent. Beneficial or deleterious effects on maize plant height due to bacterial inoculation of the seed often were not repeatable in other soils or experiments.

Keywords:

Maize; bacterial isolates; plant height,
