Effects of PGPB Inoculations on Plant Growth and Quality of Spray Carnation Cultivation in Greenhouse

Abstract

This study was carried out to reveal the effects of beneficial bacteria on the development and quality of Dianthus caryophyllus under greenhouse conditions. The carnation seedlings were treated with Enterobacter ludwigii (KF29A) and Pseudomonas fluorescens (KF31B), which have nitrogen fixation, phosphate solibilizing and siderophore production properties, Paenarthrobacter nitroguaiacolicus (KF3B) with nitrogen fixation, ACC deaminase and siderophore production, Pseudomonas sp. strain VG242B (KF5A), which carries nitrogen fixing, phosphate solibilizing, and siderophore production properties together, Paenibacillus xylanilyticus (KF63C) with nitrogen fixation, phosphate solibilizing, ACC deaminase and siderophore production properties together and Pseudoalteromonas tetraodonis (TV126C) bacteria with nitrogen fixing, phosphate solibilizing and ACC deaminase properties were applied. In the study, in which phenological and morphological observations were made, the effects of bacterial inoculations were tried to be determined. The effects of beneficial bacteria treatments on the number of petals, the number of nodes, the length between the nodes and the weight of the branches in the carnation plant were statistically insignificant; effects on the parameters of bud first bloom time, full bloom time, time from planting to first harvest, number of flower buds and stem length (p
