Farklı Katkı Maddeleri ile Takviye Edilmiş Kavak Talaşında Yetiştirilen Pleurotus eryngii İzolatlarının Verim ve Şapka Özellikleri

Öz

Çalışmanın amacı, Türkiye’nin farklı bölgelerinden izole edilen Pleurotus eryngii izolatlarının üretiminde, ayçiçeği küspesi (AK), üzüm posası (ÜP) ve yeşil ceviz kabuğu (YCK) gibi farklı katkı materyallerinin kullanım olanaklarının araştırılmasıdır. Yetiştirme ortamı hazırlığında, kavak talaşı ana materyal olarak kullanılır iken, bahsedilen katkı materyalleri yetiştirme ortamına 8:2 oranında eklenmiştir. Çalışma çerçevesinde, farklı katkı materyalleri kullanılarak hazırlanan bu yetiştirme ortamlarında üretilen P. eryngi izolatlarının misel gelişim süresi (gün), ilk hasada kadar geçen süre (gün), toplam verim (g/kg), biyolojik etkinlik (BE) ve bazı şapka özellikleri (şapka boyutları ve şapka rengi)  belirlenmiştir. Sonuçlar, üretim parametreleri ve şapka özelliklerinin yetiştirme ortamı ve izolatlardan önemli oranda etkilendiğini ve çalışmada test edilen üç katkı materyalinin her üç P. eryngii izolatının üretiminde kullanılabileceğini ortaya koymuştur. T:AK ortamında yetişen K-16 ve M-18 izolatları daha yüksek verim, BE ve şapka iriliği sergiler iken, K-20 izolatında ise T:ÜP ortamında daha yüksek değerler elde edilmiştir. Diğer ortamlara kıyasla T:YCK ortamında yetişen P. eryngii izolatlarının üretim sürelerinde bir artış görülmesine rağmen, P. eryngii yetiştiriciliğinde katkı materyali olarak yeşil ceviz kabuğu kullanımının ticari olarak uygulama potansiyeline sahip olduğu gözlenmiştir.

Yield and Fruit Body Properties of Pleurotus eryngii Isolates Grown on Poplar Sawdust Supplemented with Different Additive Materials

Öz

The aim of this study was to investigate the possibility of using sunflower meal (SFM), grape pomace (GP) and green walnut husk (GWH) as new additive materials for substrate preparation in cultivation of Pleurotus eryngii (DC. ex Fr.) isolates collected from different regions of Turkey. In addition, effect of these agro-wastes on fruit body size of P. eryngii isolates was also determined in the study. Poplar sawdust (S) was used as a base medium and additive materials were added to sawdust in a ratio of 8:2 to prepare the substrates. It has been noticed that different additive materials affects on spawn run time (day), time of first harvest (day), total yield (g/kg), biological efficiency (BE), average of mushroom weight (g), mushroom pileus diameter (mm) and stipe width (mm), stipe length (mm) of P. eryngii isolates. Yield parameters and fruit body size were greatly affected by the substrates and isolates. S:SFM showed higher yield, biological efficiency and mushroom weight average than other substrates in K-16 and M-18 isolates, whereas these parameters were height in K-20 isolate grown on S:GP. The results revealed that all the three P. eryngii isolates can grow on poplar substrate with the supplement of any kind of the tested agricultural by-products. Although, an increase in spawn running time and cultivation period length of P. eryngii isolates was observed for S:GWH compared with the other substrates, utilization of green walnut husks for Pleurotus eryngii cultivation is promising and has potential commercial application in the mushroom industry.
