Seçilmiş Bakteri İzolatlarının Kadmiyum ile Zenginleştirilmiş Topraklarda Şeker Pancarının Gelişimi ve Besin Elementi Alımı Üzerine Etkisi

Seçilen 6 bakterinin kadmiyum ile zenginleştirilmiş topraklarda yetiştirilen şeker pancarı bitkisinin gelişimi ve besin elementi alımına etkilerini belirlemek amacıyla, Sivas koşullarında saksı denemesi yürütülmüştür. Bakteriler daha önce Isparta Uygulamalı Bilimler Üniversitesi Toprak Biyoloji Laboratuvarında izole edilmiş ve mısır üzerinde test edilmiştir. Çalışmada Adana (Ad), Antalya (An), Hatay (Ha), Isparta (Is), Ordu (Or) ve Sivas (Si) illerinin her birinden izole edilen 4 bakteriden, daha önceki performansları göz önüne alınarak en etkili olan birer taneleri seçilmiştir.Çalışmada, yukarıda sözü edilen bakterilerin 5 mg kg-1 Cd ile zenginleştirilmiş toprakta yetiştirilen şeker pancarı performansı üzerindeki etkileri belirlenmiştir. Sonuçlar Cd uygulamasının bitkinin biyokütle gelişimini önemli ölçüde (p<0.05) azaltırken, bakteri aşılamanın bitkinin kuru madde ağırlığını arttırdığını göstermiştir. Bununla birlikte, Cd ile zenginleştirilmiş durumda bakteri aşılaması, bitki kuru ağırlığını daha da arttırmış, en yüksek değer 43.1 g bitki-1 ile B1 ve 5 mg kg-1 Cd uygulamasından elde edilmiştir. Tek başına bu sonuç bile belirli bakterilerin uygulanmasının kadmiyumun olumsuz etkilerini azaltabildiğini gösterir niteliktedir. B5 hariç olmak üzere kadmiyum uygulanan saksılardaki bakteri uygulamalarının hepsi bitkinin biyokütlesini artırmıştır. Kadmiyum ile çinko arasındaki antagonsitik ilişkiye uygun olarak, kadmiyum uygulamaları çinko alımını azaltmıştır. Ancak bakteri uygulamaları kadmiyum uygulanan koşullarda bile çinko alımını artırmıştır.

Influence of Selected Bacteria Isolates on Sugar Beet Growth and Nutrient Uptake in Cadmium Enriched Soil

A pot experiment was conducted in order to determine the effects of 6 selected potential PGPR on growth and nutrient uptake of sugar beet under Cd enriched soils at Sivas condition. Bacteria were previously isolated and tested on maize in Soil Biology Laboratory of Isparta University of Applied Sciences. In this study, the most effective isolates out of 4 from each province as Adana (Ad), Antalya (An), Hatay (Ha), Isparta (Is), Ordu (Or) and Sivas (Si) selected as potential PGPR considering their previously determined performance. In the study, the effects of above mentioned bacteria on sugar beet performance under 5 mg kg-1 Cd enriched condition was determined. Results revealed that Cd application significantly (p<0.05) reduced plant biomass development whereas bacteria inoculation increased plant dry matter weight. However, in the Cd enriched condition, bacteria inoculation further improved plant dry weight where the higher value was observed in dual application of B1 and 5 mg kg-1 Cd application as 43.1 g plant-1. This result alone indicates that certain bacterium application may reduce the negative effects of cadmium. Among the Cd applied pots, B5 is an exception, all bacteria application increased plant biomass development. Cadmium application also reduced zinc uptake of plant in accordance the antagonistic effect of cadmium on zinc uptake; yet, bacteria inoculation may help plant to uptake slightly more zinc even under cadmium contaminated soils.
