Effects of Enhanced UV-B Radiation on Biomass and Contents of Camptothecin and 10-hydroxy-camptothecin in Camptotheca acuminata
增强UV-B辐射对喜树幼苗生物量和两种生物碱含量的影响

The effects of enhanced UV-B radiation on biomass and contents of camptothecin and 10-hydroxy-camptothecin in Camptotheca acuminata were investigated in a pots experiment.The results showed that:(1) Comparing to the control group,the fresh weight of C.acuminata seedlings and of the various organs did not change significantly in the first 20 days after treatment.After 40 days,however,the biomass of the whole plant and the various organs was higher than in the untreated plants.Finally,the biomasses per plant ...
