摘要
以平菇为试材,将其接种到添加了不同浓度的吲哚丁酸、α?萘乙酸、赤霉素、三十烷醇、6-BA、催菇丰的PDA培养基上,通过测量菌落半径来研究不同培养基对平菇菌丝生长速度的影响。结果表明:植物生长调节剂对平菇菌丝的生长都有促进作用;同一种植物生长调节剂在低浓度时,其促进作用随植物生长调节剂浓度的增加而增强;但当浓度增加到一定值后,其促进作用随浓度的增加减弱;若浓度进一步增加,则促进作用又随浓度的增加而增强;由此可见,植物生长调节剂对真菌和植物的促进作用规律基本是一致的。
Taking Pleurorus ostreatus which was inoculated on PDA medium as material,including different concentrations of indole butyric acid, α-NAA, GA, triaeontanol, 6-BA, urging mushroom fungi respectively. The effect of different medium on growth rate were studied by measuring the colony radius. The results showed that all plant growth regulators could promote the growth of Pleurorus ostreatus. When the plant growth regulator ＇s concentration was low, the promotion would be more obvious with the concentration of plant growth regulators increasing ; but as the concentration increased to a certain value, the promotion would decline with the concentration increasing;if the concentration continued to increase, the promotion would increase with the concentration increasing. Thus,the auxo-action law of the plant growth regulators on fungi and plants was basically the same.
