| 摘要: |
| 【目的】研究杏鲍菇的营养生理特性。【方法】以杏鲍菇菌株XBG-01为供试材料，测定不同培养基中菌落的直径及菌丝生长速率，观察气生菌丝的长势，研究不同的碳源、氮源、无机盐、维生素和植物生长调节剂对杏鲍菇菌丝生长的影响。【结果】杏鲍菇能以多种单糖、双糖、多糖等作为碳源，其中以果糖、葡萄糖和甘露糖为碳源时，菌丝生长均较好，最适碳源为果糖；在供试氮源中，杏鲍菇对复合氮源、无机氮源、氨基酸均能利用，其中以蛋白胨为最适氮源，麦芽浸粉和酵母膏次之；无机盐中的1.0 g/L硫酸镁、磷酸二氢钾，维生素中6 mg/L维生素B2、烟酸以及植物生长调节剂中8 mg/L IAA、KT，均对杏鲍菇菌丝生长具有明显的促进作用。【结论】不同碳源、氮源对杏鲍菇菌丝生长有显著影响，向培养基中适量添加某些无机盐、维生素和植物生长调节剂，可提高杏鲍菇菌丝生长速率。 |

| Abstract: |
| 【Objective】 The study was made to investigate the nutrictional physiological character of Pleurotus eryngii.【Method】The size of colony and surface mycelium growth vigor were used to assess the effects of various carbon and nitrogen sources,and effects of carbon sources,mineral elements,vitamins and phytohomones on growth of P.eryngii were studied with P.eryngiiXBG-01 as the test material.【Result】 Fructose,glucose and mannose were the top three best carbon sources for mycelial growth.Fructose was the most utilized,followed by glucose and mannose.All the organic and inorganic sources investigated improved growth with peptone being the best,followed by malt flour and yeast extract paste.1.0 g/L Magnesium sulfate and monopotassium phosphate,6 mg/L vitamin B2 and nicotinic acid promoted good mycelial growth.Among the phytohormones tested,8 mg/L IAA and KT stimulated mycelial growth.【Conclusion】 The growth of P.eryngii was significantly affected by various carbon,nitrogen sources and supplementation of mineral elements,vitamins and phytohomones enhanced the growth of P.eryngii. |
