Abstract

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.

CONCLUSION

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

摘要

目的

通过内生真菌提高杭白菊的花产量。

方法

将内生真菌（球毛壳菌C4菌株和葡萄孢属C1菌株）接种到盆栽的组培苗上。测量花的产量，测定花中总黄酮和精油含量。

结果

与对照组相比，C4真菌组的鲜花和干花产量分别增加了24.81%、7.59%，C1真菌组的鲜花和干花产量分别增加了17.08%、6.87%。C4真菌组的总黄酮含量显著高于对照组，C4、C1真菌组花的总黄酮含量与对照组相比分别增加了31.79%、8.55%。C4、C1真菌组的精油含量分别增加了13.21%、18.19%。C4、C1真菌处理组各种精油成分的含量百分比与对照组相比分别增加了10.42%、8.90%。C4、C1处理组各种精油成分的含量百分比与对照组之间存在差异。
