تأثير إضافة خميرة الخبز لنوعين من وسط الزراعة في الإنتاج و تركيز بعض المركبات الكيميائية للفطر المحاري

Abstract EN

The experiment was carried out at a special farm in Homs Governorate, Syria from 24/10/2011 to 10/1/2012 by planting Pleurotus ostreatus (oyster mushroom), by using two of substrates (coarse wheat straw, sawdust).

Bread yeast has been added in two concentration (1 or 2)g/kg wet substrate.

Each of those two substrate has treated by three treatment (control, adding 1g bread yeast /kg wet substrate, adding 2g bread yeast /kg wet substrate).The results showed remarkable increasing in dry matter percentage, ash and protein in oyster mushroom fruit bodies.

As bread yeast addition in two different concentration for both two substrates significantly increased fruit body weight, yield and BE of oyster mushroom compared to control.

While for coarse wheat straw substrate, the yield increase 16.92% (whereas it reached up to 2.35 kg/7kg wet substrate) and 21.89%(it reached up to 2.45 kg/7kg wet substrate) by adding (1g/kg wet substrate) and(2g/kg wet substrate) bread yeast respectively, while production reached up to 2.01 kg/7kg wet substrate at control treatment.

For sawdust substrate, the yield increase 12.61%( it reached up to 1.34 kg/7kg wet substrate) and 24.37% (it reached up to 1.48 kg/7kg wet substrate) when bread yeast has been added by 1,2 g/kg wet substrate respectively, while production reached up to 1.19 kg/7kg wet substrate at control treatment.
