The effects of light and quantity of spawn on the sporophore and sclerotial yields of Pleurotus tuber-regium, cultivated on cotton wastes, rice straw, cocoyam peel, comcob, groundnut shell and sawdusts of Mansonia altissima, Khaya ivorensis and Boscia angustifolia were observed. The organism had sporophore and sclerotial yield values of 36.8 and 27.6 g kg(-1) waste, respectively, in cotton waste, at light quantum of 695 lux. There was a highly significant increase in yield of sclerotia (188.0 g kg(-1) waste), in total darkness, while malformed fruitbodies (sporophores) were produced in all the substrates under the same condition. Increasing the quantity of spawn from 5 to 30% reduced the period of spawn run from 13 to 6, 15 to 8 and 24 to 17 days, respectively in P. tuber-regium fruitbodies grown in cotton waste, rice straw and sawdust of B. angustifolia, with yield values of 38.0 and 20.0 g kg(-1) waste in cotton waste and rice straw. The optimal spawn levels forsclerotia formation in the two wastes were 10 and 5%, respectively. The mushroom did not produce sclerotia in corn cob and groundnut shell when exposed to light. However, maximal yield values of 286.8 and 288.4 g kg(-1) waste were obtained in both substrates in total darkness.
研究了光照和菌种用量对在棉籽壳、稻草、木薯皮、玉米芯、花生壳以及曼森尼亚、非洲桃花心木和狭叶肉叶刺茎藜锯末上栽培的瘤柄侧耳子实体和菌核产量的影响。在光照强度为695勒克斯的条件下，该菌株在棉籽壳中的子实体和菌核产量分别为36.8克/千克废料和27.6克/千克废料。在完全黑暗条件下，菌核产量显著增加（188.0克/千克废料），而在相同条件下，所有基质上均产生了畸形子实体（子实体）。将菌种用量从5%增加到30%，分别使棉籽壳、稻草和狭叶肉叶刺茎藜锯末上生长的瘤柄侧耳子实体的发菌期从13天缩短至6天、15天缩短至8天、24天缩短至17天，棉籽壳和稻草中的产量分别为38.0克/千克废料和20.0克/千克废料。两种废料中形成菌核的最佳菌种水平分别为10%和5%。在光照条件下，该蘑菇在玉米芯和花生壳中不产生菌核。然而，在完全黑暗条件下，两种基质中的最大产量分别达到286.8克/千克废料和288.4克/千克废料。
