Abstract

One of the most important strategies to increase agricultural productivity and sustainability is to use a variety of local plant growth-promoting rhizobacteria (PGPB) and their improved consortium formulations. This study aimed to determine the effect of local PGPB on plant growth and rhizome development of Trachystemon orientalis, which has great potential as an alternative food source. Six different combined microbial consortia prepared from 11 different rhizobacteria isolated from tea rhizosphere, based on their multiple beneficial effects, were applied to the rhizomes of Trachystemon orientalis planted in 1:1 (v/v) peat: perlite medium. The experiment was set up according to the randomized complete block design with three replications, five rhizomes in each replication, and rhizomes not subjected to any treatment were used as controls. PGPB consortia were detected to be effective on 14 parameters examined related to rhizome development and plant growth. The correlation heatmap revealed a strong relationship between the applications and all the parameters examined. The best result was obtained from the P4 application containing a mixture of Pseudomonas putida and Bacillus spp. This microbial cocktail can be a good alternative to chemical fertilizers, as it is both beneficial and profitable, especially in seedling cultivation of Trachystemon orientalis.

Özet

Tarımsal verimliliği ve sürdürülebilirliği artırmanın en önemli stratejilerinden biri, çeşitli yerel bitki büyümesini teşvik eden rizobakterileri (PGPB) ve bunların geliştirilmiş konsorsiyum formülasyonlarını kullanmaktır. Bu çalışmada, bitkilerin topraktan daha fazla besin maddesi almasını sağlayan Trachystemon orientalis'in bitki büyümesi ve rizom gelişimi üzerine etkisinin belirlenmesi amaçlanmıştır. Çay rizosferinden izole edilen 11 farklı rizobakteriden çok sayıdaki yararlı etkileri göz önüne alınarak hazırlanan altı farklı mikrobiyal konsorsiyum kombinasyonu 1:1 (v/v) torf:perlit ortamına dikilen Trachystemon orientalis rizomlarına uygulanmıştır. Deneme tesadüf blokları deneme desenine göre üç tekrarlamalı olarak kurulmuş olup, her tekrarlamada beş rizom yer almış ve herhangi bir uygulama yapılmayan rizomlar kontrol olarak kullanılmıştır. Çalışma sonucunda PGPB konsorsiyumlarının rizom gelişimi ve bitki büyümesi ile ilgili incelenen 14 parametre üzerinde etkili olduğu tespit edilmiştir. Korelasyon ısı haritası, uygulamalar ile incelenen tüm parametreler arasında güçlü bir ilişki olduğunu ortaya koymuştur. En iyi sonuç Pseudomonas putida ve Bacillus spp. karışımı içeren P4 uygulamasından elde edilmiştir. Mikrobiyal karışım, Trachystemon orientalis'in özellikle fide yetiştiriciliğinde faydalı ve karlı olması nedeniyle uygulanabilir olduğu ortaya koyulmuştur.
