近年来,我们观测了萘乙酸(NAA)、吲哚乙酸(IAA)、吲哚丁酸(IBA)及赤霉素(GA)等生长激素,对平菇菌丝、子实体生长和品质的影响。现整理如下,供有关方面参考。 (一)对菌丝体生长的影响:在PDA培养基中,2ppm的萘乙酸和吲哚丁酸可明显促进菌丝生长,增长率达5～7％,而吲哚乙酸和赤霉素有一定的抑制作用。大于2ppm吲哚乙酸的抑制作用最强。在木屑培养基中,1ppm的各种生长激素都能不同程度地促进菌丝生长,5ppm的萘乙酸和吲哚丁酸效果最好,菌丝率增长可达7～10％。大于1ppm的吲哚乙酸和赤霉素有抑制作用。木屑培养
In recent years, we observed the effects of growth hormone such as NAA, IAA, IBA and GA on the growth and quality of mycelium and fruiting body of Pleurotus ostreatus . Now collated as follows for reference. (I) Effects on mycelial growth: In PDA medium, 2ppm naphthaleneacetic acid and indole butyric acid can significantly promote mycelial growth, the growth rate of 5 to 7%, while indole acetic acid and gibberellin have Certain inhibition. Indole acetic acid greater than 2ppm showed the strongest inhibitory effect. In the sawdust medium, 1ppm of all kinds of growth hormone can promote mycelial growth to varying degrees, 5ppm naphthaleneacetic acid and indole butyric acid best, mycelium rate increased up to 7 to 10%. Indoleacetic acid and gibberellin greater than 1 ppm have inhibitory effects. Wood shavings
