[The effect of different endophytic fungi on Chrysanthemum morifolium output and quality].
OBJECTIVE
To enhance the flowers yield of Chrysanthemum morifolium by endophytic fungi.


METHODS
Endophytic fungi (Chaetomium globosum strain C4 and Botrytis sp. strain C1) were inoculated to the plantlets which were planted in the pots. The output of the flowers was measured, the total flavonoids and essential oil contents of the flowers were determined.


RESULTS
Compared to that of the control, fresh and dry outputs of the fungi C4 group increased 24.81%, 7.59%, fresh and dry outputs of the fungi C1 group increased 17.08%, 6.87%. Total flavonoids content of the fungi C4 group was higher than that of the control remarkably, fungi C4, C1 groups flowers total flavonoids content increased 31.79%, 8.55% compared to that of the control. Essential oil content of the fungi C4, C1 groups increased 13.21%, 18.19% respectively. The content percentage of various essential oil components of the fungi C4, C1 groups increased 10.42%, 8.90% compared to that of the control respectively. There were differences among the content percentage of various essential oil components of fungi C4, C1 treated group and the control's.


CONCLUSIONS
The two fungi could build the symbiosis relation with the Chrysnthemum morifolium, which may cause them to enhance the output and quality finally.
