THE EFFECT OF SOME ANGELICA L. SP. HYDROSOLS ON SEED GERMINATION AND INITIAL PLANT GROWTH


Full text

The hydrosols obtained from rhizomes with roots and aerial part of Angelica L. species were assessed in relation with their possible influence on plant germination and growth. Tests were carried with several test-species and germination and growth were evaluated up to 72 h. Germination rates were, in some cases, reduced following treatment with hydrosols. The development of plantlets, in terms of root and hypocotyl length, was also inhibited, especially by hydrosols of A. archangelica. Spectrophotometric analysis in UV range and pH of hydrosols are also presented. Chemical compounds present in hydrosols belong to aromatic and terpenoid categories, with younger aerial part and rhizome hydrosols exhibiting the most powerful effect on germination and growth. Thus, a previously not tested potential of mentioned hydrosols is described
