不同基质及丛枝菌根真菌对黄花蒿育苗的影响

为筛选出适宜黄花蒿幼苗生长的理想基质,比较了6种不同基质以及接种丛枝菌根真菌对黄花蒿幼苗生长的影响.结果表明:在供试的6种基质中,泥炭∶河沙=1∶2基质中的黄花蒿种子最早出现萌芽及第1片真叶,发芽率、幼苗苗高、根长、鲜重、干重和菌根侵染率均最高,且接种丛枝菌根真菌摩西球囊霉后促进效果更显著.泥炭与河沙按1:2比例混合的基质可作为培育黄花蒿菌根化苗的理想基质.

Effects of different substrates and arbuscular my corrhizalfungi on seedling growth of Artemisia annua

In order to select suitable substrate for seedling growth of Artemisia annua, experiments wereconducted to study the effects of six different substrates and inoculation with arbuscular mycorrhizal fungi on theseedling growth of A annua. The results showed that the seeds of A annua in the mixture substrate with the volumeratio of peat and sand at 12 germinated earliest and the first true leaf appeared. Moreover, the germination rate,seedling height, root length, fresh weight, dry weight and mycorrhizal colonization rate in this mixture substrate werethe highest among the six substrates. The promoting effects on seedling growth of A. annua were more significant afterinoculation with arbuscular mycorrhizal fungi. Therefore, the mixture substrate with the volume ratio of peat and sandat 12 can be used as an ideal substrate for mycorrhizal seedling of A. annua in the seedling production.
