通过盆栽接种试验,研究丛枝菌根(AM)真菌对药用植物黄花蒿的生长、营养吸收和药效成分的影响.结果表明:接种摩西球囊霉和地表球囊霉增加了黄花蒿对N、P、K的吸收,及叶片叶绿素含量、净光合速率、气孔导度、蒸腾速率、茎粗和地上生物量,尤其以接种摩西球囊霉的促进作用更强;接种摩西球囊霉后植株茎、小枝和叶中的青蒿素含量分别提高了32.8%、15.2%和19.6%,接种地表球囊霉后分别提高了26.5%、10.1%和14.9%;接种摩西球囊霉和地表球囊霉的黄花蒿地上部的挥发油收油率比未接种的分别提高45.0%和25.0%,而且挥发油成分发生了改变.
The effects of arbuscular mycorrhizal (AM) fungi on the growth, nutrient absorption and pharmacodynamic components of medicinal plant Artemisia annua were studied by pot experiment.The results showed that the effects of A. annua on A. griseus, The absorption of N, P and K, as well as the leaf chlorophyll content, net photosynthetic rate, stomatal conductance, transpiration rate, stem diameter and aboveground biomass, especially the promotion by M. gossypii were stronger. Artemisinin content in stems, twigs and leaves of plants increased by 32.8%, 15.2% and 19.6%, respectively. After inoculated with A. gossypii, the contents of artemisinin increased by 26.5%, 10.1% and 14.9%, respectively. The yield of volatile oil from aerial parts of Artemisia sacralformis increased by 45.0% and 25.0%, respectively, compared with the uninoculated ones, and the volatile oil components were changed.
