Abstract:
Taking Armillaria mellea of Gastrodia elata Blume isolated and screened as the experimental material，the effects of different concentrations of NAA on the mycelium and rhizomorph emergence date，rhizomorph length，biomass and growth status of Armillaria mellea of Gastrodia elata Blume were investigated by using ten different concentrations of NAA added in the PDA basal culture media.The results showed that the mycelium and rhizomorph emergence dates of No.4(5.0 μg/mL) treatment were earlier than those of other treatments；the rhizomorph length of treatments from 1 to 5(0.5,1.0,2.5,5.0,10.0 μg/mL) were obviously longer than CK，while treatments from 6 to 9(25,50,100,250 μg/mL) were much worse than CK；the biomass of No.4 treatment was the highest among all the treatments；and the growth status of No.3 and 4 treatments was much better than others.On the basis of comprehensive comparison and analysis，No.4 treatment was the best one for the growth of Armillaria mellea，which laid some foundation for the cultivation，production，research and exploitation of Armillaria mellea in the future.
