Allelopathic properties of soils of perennial populations Patrinia scabiosifolia and Patrinia rupestris
Abstract
Methods. The experiment was conducted during the 2010-2014 growing seasons at the field hospital of FED RAS. As a control group the soil under the grass and herbs was used. Soil samples were collected from a depth of 0-10 sm layer. Distance from the donor plant was defined as 0.5 projection of his aerial part. Results. The experiment revealed the allelopathic activity of soils of natural populations of P. rupestris and P. scabiosifolia. Index of al-lelopathic activities varied widely, stem sprouts tissue were the most sensitive to the inhibitory effects, and maximum stimulating effect was shown on root tissue. Conclusions. It was found that P rupestris and P scabiosifolia are edificators providing in mature generative condition within Phytogenic field stimulation, in the case of P scabiosifolia, and inhibiting, in the case of P rupestris, effect on the growth and development of seed, thereby influencing the structure of plant communities on the territory of their habitat.
