Yerinde in situ Korunan Yabani Buğday Türleri, Eşlik Eden Bitkiler ve Toprak Özellikleri Arasındaki İlişkiler

Buğdayın atalarının ekolojileri ve bunlara eşlik eden bitki türlerinin etraflıca bilinmesi, bitki bilimiyle uğraşan bilim adamları için önem taşımaktadır. Bu çalışma Şanlıurfa’nın Ceylanpınar Tarım İşletmesinde bulunan 5 yabani buğday Aegilops spp. L. ve Triticum spp. L. akrabası ile bunların bulundukları yerlerin toprak tipleri, çevresel ve dış değişkenlerine yoğunlaşmak üzere uygulanan bir vaka çalışması niteliğindedir. Çalışmanın amacı, alanda bulunan hedef türlerin mevcudiyetini etkileyen temel fiziki koşulların ortaya konmasıdır. Modern buğdayların evrimiyle ilişkili olan aşağıdaki beş yabani buğday türü araştırma materyalini oluşturmuştur: Aegilops speltoides Tausch var. speltoides keçi otu , Aegilops speltoides Tausch var. ligustica Savign. Fiori keçi otu , Aegilops tauschii Coss. var. meyeri Griseb. ex Ledeb. Tausch keçi otu , Triticum monococcum L. ssp. aegilopoides Link Thell. yabani siyez ve Triticum turgidum L. ssp. dicoccoides Körn. ex Asch.& Graebn. yabani gernik . Hedef türler ile Poaceae familyası türleri ve eşlik eden otsu bitki türleri arasında ilişki bulunurken, çok yıllık bitkilerde benzer bir ilişki gözlenmemiştir. Taşlılıkla yabani gernik arasında kuvvetli bir ilişki bulunmuştur. Yabani siyezde hafif taşlılık ve hafif otlatmayla, Ae. speltoides ligustica türünde de çok taşlılık ve aşırı otlatma ile ilişkili bulunmuştur

Anahtar Kelimeler:

Aegilops, Triticum, in situ muhafaza, toprak karakteristikleri, yabani buğday

Relationship Between in situ Conserved Wild Wheat Species, Associated Plants and Soil Characteristics

A comprehensive knowledge of the ecology and associating plant species of wheat progenitors is important for plant scientists. This study was designed as a case study to focus on the relation between 5 wild relatives of wheat Aegilops spp. L. and Triticum spp. L. , their associated soil types and environmental and external variables in the Ceylanpınar State Farm of Şanlıurfa Province. The aim of the study was to explain the major physical factors affecting the existence of target species in the area. The following wild wheat species, which are all related with evalution of modern wheat were taken into consideration: Aegilops speltoides Tausch var. speltoides goat grass , Aegilops speltoides Tausch var. ligustica Savign. Fiori goat grass , Aegilops tauschii Coss. var. meyeri Griseb. ex Ledeb. Tausch's goat grass , Triticum monococcum L. ssp. aegilopoides Link Thell. einkorn and Triticum turgidum L. ssp. dicoccoides Körn. ex Asch.& Graebn. emmer . Association was observed between the target species, Poaceae species and herbaceous plants, while no association was noticed with perennial plants. Strong association was observed between rockiness and emmer. Einkorn was associated with slightly stoniness and slight grazing while Ae. speltoides ligustica was related with very stony areas and excessive grazing
