摘要
香菇Lentinula edodes是世界第一大食药用真菌,随着香菇工厂化生产逐渐规模化、周年化、标准化,香菇工厂对环境集约化及智能化控制的要求也越来越高。光照是香菇生长发育过程中重要的环境因素,本研究将转色后的香菇菌棒分别置于红光(R)、绿光(G)、蓝光(B)、红绿光(RG)、红蓝光(RB)、绿蓝光(GB)、红绿蓝光(RGB)7种光线下照射培养,以黑暗处理(CK)的香菇菌棒作为对照,探究不同光质光照对香菇子实体农艺性状与质构品质的影响。结果表明:红绿蓝光照射下单个菌棒蕾数最多,为24.33个,黑暗处理下蕾数最少,16.17个;蓝光和红绿蓝光照射下子实体产量较高,达到228.12g/棒和220.82g/棒;红光条件下子实体产量最低,为173.53g/棒。不同光质光照对香菇子实体的形态特征有影响,红光和黑暗环境会影响子实体菌盖和菌柄的颜色,使其颜色偏淡,色彩饱和度增加,并且促使菌柄的生长。绿光和蓝光照射下子实体农艺性状和质构品质好。本研究表明蓝光可以作为香菇工厂化生产出菇阶段的首选光质。
With the growth of industrialized,cyclical and standardized production of Lentinula edodes,the requirement of environmental intensification and intelligent control in production process is increased by a big margin.Light is an important environmental factor in the growth and development of L.edodes.In this study,after mycelial pigmentation stage,L.edodes growing on cultivated logs was exposed to seven kinds of light,red light(R),green light(G),blue light(B),red-green light(RG),red-blue light(RB),green-blue light(GB),and red-green-blue light(RGB),and dark was treated as control,to explore the effects of different light illumination on the agronomic traits and texture quality of L.edodes fruiting body.The results showed that the number of fruiting bodies on single cultivated log under RGB was maximum,averagely 24.33 per log,while CK was the least(16.17).The fruiting body yield under B and RGB treatment was 228.12g and 220.82g respectively per cultivated log.Under R illumination,the yield was lowest,173.53g per cultivated log.Red light and dark environment affects the coloration of the pileus and stipe,makes the pileus and stipe light-colored,increasing color saturation and promoting the growth of stipe.The agronomic traits and texture quality of L.edodes fruiting body under green and blue light irradiation were fine.The results indicated that blue light was preferable for L.edodes production at fruiting stage.
