Lycopersicon esculentum Mill. fideciklerine farklı konsantrasyonlarda uygulanan alüminyum etkilerinin LV SEM ile incelenmesi

Bu çalışmada Lycopersicon esculentum Mill. cv. H-2274 (domates) fıdeciklerinde artan alüminyum konsantrasyonlarına bağlı olarak gözlenen büyüme inhibisyonları düşük vakumlu Scanning Elektron Mikroskobu Mikrografları (LV-SEM) ve EDX Analizleri (Energy Dispersive X-Ray Microanalysis) ile incelendi. Çalışmamızda düşük konsantrasyonlarda uygulanan alüminyum kök emici tüyleri gelişiminde artışlara neden olurken, özellikle 200 ppm alüminyum konsantrasyonundan itibaren de düşüşler söz konusu idi. 5O ppm alüminyum konsantrasyonundan itibaren hipokotil epidermal hücrelerinde uzama büyümesinin önemli ölçüde indirgendiği gözlenirken, alüminyum uygulamalarına bağlı olarak kotiledonların anatomik yapılarında kaydedilen en belirgin farklılık alt epidermal hücrelerde stoma sayılarında saptanan düşüştü. L. esculentum Mili. cv. H-2274 (domates) fıdeciklerinin kökçük ve hipokotil epidermal hücrelerinin bazı makro ve mikro besin elementleri içeriklerinin de toksik konsantrasyonlarda (500 ve 1000 ppm) uygulanan alüminyumun etkisiyle değişebildiği görüldü.

Study of aluminum effects of absorption applied in different concentrations to Lycopersicon esculentum Mill. Seedlings by LV SEM

In that study,growing up inhibitions of Lycopersicon esculentum Mill.cv.H-2274 seedlings has been studied by low vacuum Scanning Electron Microscope (LV-SEM) ,and EDX (Energy Dispersive X-Ray Microanalysis) analysis. They were observed according to aluminum concentrations. As aluminum concentrations especially beginning from 200 ppm caused to decreases, effects of aluminum which were applied in low concentrations caused to increases in the growing of root hairs. The aluminum concentration from 50 ppm on, the growing in the length was observed and showed that it was low in the epidermal cells of hypocotyl. It is also found that the number of stomata in the epidermal cells decreased according to the addition of aluminum. Contents of some macro and micro nutrient elements for the root and hypocotyl cells of Lycopersicon esculentum Mill. cv. H-2274 seedlings were found that they changed with effects of the addition of aluminum in the toxic concentration (500 and 1000 ppm).
