摘　　要：对金针菇(Flammulina filiformis)子实体早开伞程度进行分级,并以菌盖直径为主要指标,考察不同体积浓度(3%和1.5%)CO_(2)和光照(蓝光400 lx)对早开伞的影响,同时检测早开伞和未开伞子实体中激素含量。结果表明:3%CO_(2)可以有效抑制菌盖开伞;与对照(黑暗条件,未开伞)相比,光照组菌盖直径增大、早开伞严重。在早开伞的菌盖中,9种激素含量减少,1种激素含量增加;而在早开伞的菌柄中,7种激素含量增加,3种激素含量减少。研究结果为工厂化生产中解决金针菇早开伞问题提供参考。Early pileus opening during the development of Flammulina filiformis fruiting bodies seriously reduces its commodity value and needs to be addressed in factory production. The degree of early pileus opening was classified, and then the effects of CO_(2)(volumetric concentrations of 3% and 1.5%) and blue light illumination(400 lx) on early pileus opening were investigated. Using pileus diameter as the primary index,hormone contents were determined in both early pileus opening fruiting bodies and normal fruiting bodies with pilei remaining unopened. The results showed that 3% CO_(2) effectively inhibited pileus opening. Compared with the control(cultivated in darkness, pilei unopened), the blue light group showed increased pileus diameter and serious early pileus opening. Compared with the control, the contents of 1-aminocyclopropane-1-carboxylic acid, zeatin, trans-zeatin, N6-isopentenyladenosine, methyl jasmonate, abscisic acid, jasmonic acid, gibberellic acid and jasmonic acid-isoleucine in early opening pilei were decreased, whereas the content of auxin in early opening pilei was increased. In the stipes of the early pileus opening fruiting bodies, the contents of 1-aminocyclopropane-1-carboxylic acid, trans-zeatin, N6-isopentenyladenosine, methyl jasmonate,auxin, gibberellic acid 7 and jasmonic acid-isoleucine were increased and the contents of zeatin, 6-(γ,γ-dimethylallylamino) purine and gibberellic acid 4 were decreased. These results provided a reference for solving the problem of early pileus opening in F. filiformis during factory production.
