摘要:
为了探索光质对刺芹侧耳原基发生的影响,将长满菌丝体的菌包进行不同光质(红光、黄光、绿光、蓝光、白光、黑暗)处理,观察记录原基分化及子实体生长状况,并测定原基分化过程中的胞外酶活性和海藻糖含量。结果显示:不同光质条件下原基发生时间略有差异,菇蕾分化差异明显;与工厂化生产常用的白光照射条件相比,绿光处理组中子实体的农艺性状更优,菌柄直径和长度均加长,菌盖直径相应变大,但生物学效率差异不显著;不同光质处理对羧甲基纤维素酶、半纤维素酶活性的影响不够显著,对淀粉酶的影响较大。原基分化期红光、绿光、白光、黑暗四个处理组中的海藻糖含量均呈现下降趋势;黄光与蓝光处理组中该指标的变化相似,在原基形成时出现一个极大值,具体缘由有待进一步探究。本研究结果表明绿光可以作为刺芹侧耳工厂化生产的首选光质。
Abstract:
To evaluate the effects of different light conditions on primordium differentiation of Pleurotus eryngii, the cultivation bags fully covered with mycelia were treated under different lights conditions (red light, yellow light, green light, blue light, white light and dark light) to observe primordium differentiation and the growth status of fruiting bodies, also to determine the extracellular enzyme activity and trehalose content during primordium differentiation. The results displayed that primordium formation time was slightly different under different light conditions, but the differentiation status was obviously different. However, compared with white light conditions commonly used in factory production, the agronomic traits of the fruiting bodies in the green light treatment group were better, both the diameter and length of the stalks were longer, and the diameter of the caps became larger, but the difference in biological efficiency was not significant. The effect of different light treatments on carboxymethyl cellulase activity and hemicellulase were not obvious, but amylase activity was significantly different. The content of trehalose in red, green, white and dark treatment groups showed a downward trend in primordia period. The change of this index in the blue light treatment group was similar, and a maximum value appeared at the primordium formation. The specific reason needs further investigation. The results of this study showed that green light can be used as the preferred light condition for Pleurotus eryngii factory production.
