Abstract
To explain ecological significance of plant residues of Syringa josikaea Jacq. f., S. microphylla Diels. and S. persica L. the effect of theirs decay products on allelopathic properties of soil during 18 months was studied. Under greenhouse conditions crushed roots, fallen flowers and leaves, and mixture thereof (1:1:1) of the Syringa species were mixed (at 2 % to soil weight) with grey forest soil collected from the corresponding areas of the arboretum of M.M. Gryshko National Botanical Garden of the NAS of Ukraine. The grey forest soil (fallow) without plant residues was used as control. Analysis of allelopathic activity by direct bioassay method indicated that phytotoxicity increased in soil with decaying residues. Volatile and watersoluble decay products of the Syringa species residues inhibited growth of plant-acceptors (Lepidium sativum L., Amaranthus paniculatus L., Triticum aestivum L., Cucumis sativus L.). Theirs allelopathic activity depended on decay time, type of plant material and sensibility of used plantacceptors. C. sativus was the most sensitive test-object. Cytostatic effect (bioassay – number of C. sativus lateral roots) of soil volatile and water-soluble substances under decay of plant residues was found. Decay of the Syringa species residues promoted accumulation of phenolic compounds in soil. Thus, the Syringa species residues are source of allelochemicals which are released into environment by means of theirs decay. This should be considered under long-term cultivation.
