abstract:
In a field experiment conducted in 1999-2003 on sandy soil, the effect of 0.5% Ekolist, 0.5% Koniferen Balsam and 0.5% BioTrissol on growth, development and yields of American ginseng (Panax quinquefolium L.) was investigated in successive four years of vegetation. Twice a year spraying with 0.5% solution of Ekolist resulted in improving healthiness and plant population, increase of above and under ground parts weight as well as content and yields of ginsenosides (the last one was twice as high as on control). Ginseng spraying with BioTrissol was connected with significant increase in above ground parts of plants weight and dimensions and – to a slight extent – roots weight and active substances content in raw material. There was observed a protection effect of Ekolist and BioTrissol shown as lower disease infestation rate and higher amount of plants surviving till harvest. Foliar fertilisation with Koniferen Balsam increased the weight of American ginseng plants and ginsenosides content in roots, and positively affected seed yields. Combined spraying with 0.5% solution of Ekolist and Koniferen Balsam, and especially BioTissol, caused significant improvement of features examined, plant healthiness, and content of ginsenosides.
