It has been shown that Saharan soil may have the potential of producing bioavailable iron when illuminated with visible light and also it has some essential macro and micro nutrient elements. In this study the impact of various growth media on development of some bread wheat Triticum aestivum L. and durum wheat Triticum durum L. cultivars have been investigated. As a four different nutrient media, Hewitt nutrient solution [1], illuminated and non-illuminated Saharan desert soil solutions and distilled water have been utilized. Shoot length cm.seedling-1 , leaf area cm2 seedling-1 and photosynthetic pigments [chlorophyll a, chlorophyll b and carotenoids, mg ml-1 g fresh weight g fw -1] have been determined. The results of this study indicate that, wheat varieties fed by irradiated Saharan soil solution gave comparable results to Hewitt nutrient solution.

Anahtar Kelimeler

Saharan desert soil, natural fertilizers, bread and durum wheat Triticum sp. L., seedling, photosynthetic pigments

Sahra Çöl Toprağı ile Organik Tarım: Gübrelere Bir Alternatif Olabilir mi?

Öz

Sahra toprak çözeltisinin görünür ışık ile aydınlatıldığı zaman biyolojik kullanılabilir demir üretme potansiyeline sahip olabileceği gösterilmiştir, ayrıca bu toprak bazı temel makro ve mikro besin öğeleri içermektedir. Bu çalışmada, farklı besin ortamlarının ekmeklik buğday Triticum aestivum L. ve makarnalık buğday Triticum durum L. ’ın bazı çeşitlerinin fide gelişimi üzerine etkileri araştırılmıştır. Besin ortamı olarak; Hewitt besin çözeltisi, ışıklandırılmış ve karanlıkta bırakılmış Sahra çöl toprağı çözeltisi ve deiyonize su kullanılmıştır [1]. Fide uzunluğu cm.fide-1 , yaprak alanı cm2.fide-1 ve fotosentetik pigmentler klorofil a, klorofil b ve karotenoidler c+x , mg.ml-1 g taze ağırlık-1 belirlenmiştir. Bu çalışmanın sonuçları göstermektedir ki, aydınlatılmış Sahra toprak çözeltisi ile beslenen buğday çeşitleri Hewitt besin çözeltisi ile karşılaştırılabilir sonuçlar vermiştir

Anahtar Kelimeler
