Characteristics of seasonal and spatial variations of proanthocyanidins content in Elaeagnus angustifolia and effect of salicylic acid on its accumulation
In this paper, we took Elaeagnus angustifolia as material. The paper studied characteristics of seasonal and spatial variations of proanthocyanidins content. There was an apparent difference in proanthocyanidins content of the leave from May to October, the maximim content of proanthocyanidins in October was 34.36 mg·g-1 DW, while proanthocyanidins content in July was only 17.16 mg·g-1 DW. Content of proanthocyanidins in diferernt organs of Elaeagnus angustifolia from the high to low was bark>root>leave>annual branch. We also studied the effects of salicylic acid on its accumulation among the different organs of Elaeagnus angustifolia were studied. The result showed that spraying 400 mg·L-1 salicylic acid chould enhance remarkablely proanthocyanidins content in the leave, annual branch and bark of Elaeagnus angustifolia, the maximal increment of proanthocyanidins content was 76.48%, 53.27% and 28.06% respectively on the third day after treatment.
