Abstract

In our study, the effects of excess boron which is a strategic mineral for Turkey and necessary for plants as a micro element has been researched on root development of sunflower (Helianthus annuus L.cv. Sambro No.5).The seeds of sunflower germinated under in vitro conditions. Murashige- Skoog recipe was used as nutrient medium. The amount of boron was adjusted by changing the amount of boric acid four times fold (24.8 mg/lt) than its normal amount in recipe. The excess boron resulted a reduction in the xylem arch numbers of vascular tissue of root from 8 to 4 numbers besides an increase in lateral root formation as determined in anatomical and morphological observations.

Özet

Çalışmamızda, bitkilerin mikro element olarak gereksinim duydukları, Türkiye için stratejik bir önemi olan borun ayçiçeği (Helianthus annuus L.cv. sambro No.5) bitkisinin kök gelişimine etkileri araştırılmıştır.Ayçiçeği tohumları in vitro koşullarda çimlendirilmiştir. Besin ortamı olarak Murashige-Skoog reçetesi kullanılmıştır. Ortamın bor miktarı borik asit miktarının normal reçete miktarının 4 katı fazla olarak (24,8g/lt) değiştirilmesiyle ayarlanmıştır. Anatomik ve morfolojik çalışmaların sonucunda, bor fazlalığı kökün vasküler silindirindeki ksilem kolu (ark) sayısında 8 den 4’e bir azalmaya yol açarken lateral kök oluşumunda da bir artışa neden olmuştur.
