در این پژوهش جدایه مخمر A5 از گونهCandida membranifuciens و جدایه A6 از گونه Pichia guilliermondiiبه صورت انفرادی و مخلوط با سیلیکون (Si) برای کنترل بیماری کپک خاکستری سیب با عامل Botrytis cinerea مورد ارزیابی قرار گرفتند. آزمایش اثر غلظتهای گوناگون سیلیکون بر روی جدایههای مخمر در شرایط آزمایشگاه نشان داد سیلیکون سبب کاهش رشد مخمرها میگردد. همچنین سیلیکون مانع جوانهزنی اسپور قارچ عامل بیماری در غلظتهای بالای 8/0% w/v میگردد. نتایج آزمایشات در شرایط انبار نیز نشان داد مخلوط جدایه+ A5 سیلیکون 2/0درصد و جدایه+ A6 سیلیکون 2/0 درصد با قطر لکه برابر با 87/3 و 48/3 میلی متر در دمای 4 درجه سانتی گراد و همچنین در دمای20 درجه سانتی گراد تیمار +A5 سیلیکون 2/0 با ایجاد قطر لکه معادل 23/5 میلی متر، بیشترین کنترل کنندگی را نسبت به دیگر تیمارها به صورت انفرادی و مخلوط با سیلیکون دارند. توانایی مخلوط جدایه مخمر A5 و سیلیکون 2/0 درصد در القای پاسخهای دفاعی در بافت سیب نشان داد این مخلوط چهار روز بعد از مایه زنی عامل بیماری فعالیت آنزیم کاتالاز را کاهش میدهد. علاوه بر آن این مخلوط دو روز بعد از مایه زنی سبب افزایش فعالیت آنزیم پراکسیداز و ترکیبات فنلی نیز میگردد. مطابق نتایج این پژوهش مخلوط مخمرها بهمراه سیلیکون با افزایش القاء مقاومت در بافت میوه سیب، سبب بهبود کنترل بیولوژیک میگردند.
