Bazı ekolojik faktörlerin doğal mantar verimliliği üzerindeki etkisi

Öz

Yabani mantarlar, özellikle de ayı mantarı (Boletus edulis) yiyecek ve ilaç sanayiinde kullanılmalarının yanı sıra ekolojik ve rekreasyonel önemlerinden ötürü en kıymetli odun dışı orman ürünleri arasındadır. Yabani mantarların giderek artan sosyoekonomik değerleri, bu ürünlerin odun üretimine bir alternatif olarak düşünülmesine neden olmaktadır.  Mantar ürünlerine dayalı ekosistem hizmetlerinin sürdürülebilir orman amenajman planlarına entegrasyonu, mantar verimliliği ile ekolojik değişkenler arasındaki ilişkilerin sayısal olarak anlaşılması ile mümkündür. Bu araştırmada, eğim, bakı ve yükseklik gibi bazı ekolojik değişkenlerin ayı mantarı (Boletus edulis) verimliliği üzerindeki etkisi değerlendirilmiştir. Çalışmada kullanılan mantar envanter verileri Bicik Planlama birimi sınırları içerisindeki 75 adet devamlı örnekleme alanından elde edilmiştir. Tek yönlü varyans analizi sonuçlarına göre ilgili mantar verimliliği ile meşcere eğim ve bakısı arasında anlamlı bir farklılık gözlemlenirken, meşcere yükseltisi ile anlamlı bir farklılık tespit edilememiştir. Buna göre, kuzey bakılı alanlar ile eğimin %20-30 arasında olduğu meşcereler sırasıyla 6.5 kg/ha-116.7adet/ha ve 33 kg/ha-333.3adet/ha değerleri ile diğer eğim ve bakı gruplarına göre daha düşük miktarda mantar verimliliğine sahip olmaktadır. Elde edilen bu sonuçlar mantar verimliliği ile farklı ekolojik değişkenler arasındaki ilişkilerin net olarak belirlenebilmesi için mevcut analizlerin farklı ekosistemlerdeki değerli tüm doğal mantar türleri için yaygınlaştırılması gerektiğini göstermektedir.

Influence of some ecological variables on wild mushroom (Boletus edulis) productivity

Öz

Wild mushrooms, Boletus edulis in particular are among the most important non-wood forest products (NWFPs) all over the world due to their nutritional, medicinal, ecological and recreational importance. Increasing socioeconomic value of wild mushrooms is made consider these products as an alternative for timber. Integrating mushroom-based ecosystem services into sustainable forest management plans requires understanding of the relationships between mushroom yields and its ecological drivers. This study evaluated the influence of some ecological variables such as slope, aspect and altitude on the productivity of wild mushroom, Boletus edulis. Mushroom data was collected from 75 permanent plots in Bicik planning unit covered by mixed even aged forest. Significant differences were found among aspect and slope classes whereas there were no differences among elevation classes with one-way ANOVA analysis. According to the results lower mushroom productivity was found in the areas of north aspects or slopes between 20-30% with 6.5 kg/ha-116.7unit/ha and 33 kg/ha-333.3unit/ha respectively than the other aspect and slope groups. This study showed that to obtain general knowledge relating to the effects of more ecological factors on mushroom productivity further research efforts is needed for all valued wild mushrooms, in the different ecosystems.
