Seed to seed allelopathic effects between aromatic and medicinal plants and weed species hoary cress (Lepidium draba L.)

The aim of the research was to determine allelopathic interaction between seeds of aromatic and medicinal plants and seeds of weed species hoary cress (Lepidium draba L.). The effect of chives, dill, anise, common wormwood, hyssop, lavender, marjoram and thyme seed on germination and initial growth of weed was evaluated in cogermination experiment in Petri dishes under laboratory conditions. The highest reduction in germination of hoary cress seeds was recorded in treatment with dill seeds for 35.3%. Seeds of lavender, anise and wormwood also decreased germination, and showed increase in seed mean germination time. Aromatic and medicinal plants showed both negative and positive effect on root and shoot length of weed seedlings. Significant positive effect on seedlings fresh weight, up to 18.0%, was recorded in treatments with anise, hyssop and chives.
