Abstract

Yield and commercial quality in cut flower production are determined by several traits, including plant growth, flowering time, flower number, flower diameter, and flower stem characteristics. Intensive mineral fertilizer use and low nutrient-use efficiency may increase production costs and contribute to nutrient losses and environmental problems. Therefore, interest in biological approaches that promote plant growth, improve nutrient-use efficiency, and reduce environmental impacts is increasing. Plant growth-promoting rhizobacteria (PGPR) can improve plant growth and mineral nutrition through mechanisms such as phytohormone production, biological nitrogen fixation, phosphate solubilization, siderophore production, ACC deaminase activity, and stimulation of root development. This review evaluates the effects of PGPR applications on vegetative growth, mineral nutrition, flowering, and flower quality in cut flower production based on available research findings. The evidence indicates that suitable PGPR strains can improve plant height, leaf development, root and shoot biomass, nutrient uptake, bud and flower number, flower diameter, and flower stem length and thickness. However, these effects vary with bacterial strain, plant species and cultivar, application method, growing medium, and fertilization level, and enhanced vegetative growth does not always result in a comparable improvement in flowering and flower quality. Current evidence suggests that PGPR should be considered not as a complete substitute for mineral fertilizers, but as a complementary biological tool that can support nutrient-use efficiency and commercial flower quality. Wider commercial use requires the identification of plant–strain compatibility, optimization of application methods, and standardized studies under commercial production conditions.

Özet

Kesme çiçek yetiştiriciliğinde verim ve ticari kalite; bitki gelişimi, çiçeklenme zamanı, çiçek sayısı, çiçek çapı ve çiçek sapı özellikleri gibi birçok ölçüt tarafından belirlenmektedir. Mineral gübrelerin yoğun kullanımı ve düşük besin kullanım etkinliği, üretim maliyetlerini artırabilmekte, besin elementi kayıplarına ve çevresel sorunlara neden olabilmektedir. Bu nedenle bitki gelişimini destekleyen, besin kullanım etkinliğini artıran ve çevresel etkileri azaltan biyolojik uygulamalara yönelik ilgi giderek artmaktadır. Bitki gelişimini teşvik eden rizobakteriler (PGPR), fitohormon üretimi, biyolojik azot fiksasyonu, fosforun çözünür hâle getirilmesi, siderofor üretimi, ACC deaminaz aktivitesi ve kök gelişiminin uyarılması gibi mekanizmalar aracılığıyla bitki büyümesini ve mineral beslenmeyi iyileştirebilmektedir. Bu derlemede, kesme çiçek yetiştiriciliğinde PGPR uygulamalarının vejetatif gelişme, mineral beslenme, çiçeklenme ve çiçek kalitesi üzerindeki etkileri mevcut araştırma bulguları ışığında değerlendirilmiştir. Bulgular, uygun PGPR suşlarının bitki boyu, yaprak gelişimi, kök ve sürgün biyokütlesi, besin elementi alımı, tomurcuk ve çiçek sayısı, çiçek çapı ile çiçek sapı uzunluğu ve kalınlığı gibi özellikleri iyileştirebildiğini göstermektedir. Bununla birlikte, etkilerin bakteri suşu, bitki türü ve çeşidi, uygulama yöntemi, yetiştirme ortamı ve gübreleme düzeyine bağlı olarak değiştiği; vejetatif gelişmedeki artışın her zaman çiçeklenme ve çiçek kalitesine aynı ölçüde yansımadığı görülmektedir. Mevcut kanıtlar, PGPR’nin mineral gübrelerin tam ikamesinden çok, besin kullanım etkinliğini ve ticari çiçek kalitesini destekleyebilecek tamamlayıcı bir biyolojik araç olarak değerlendirilmesi gerektiğine işaret etmektedir. Ticari kullanımın yaygınlaştırılması için bitki–suş uyumunun belirlenmesine, uygulama yöntemlerinin optimize edilmesine ve ticari üretim koşullarında standartlaştırılmış araştırmaların yürütülmesine gereksinim vardır.
