Allelopathic impact of some dominants in clean cuttings of Scots pine forest under climate change conditions

Vaida Šėžienė, Ligita Baležentienė, Remigijus Ozolinčius


The objective of the study was to evaluate allelopathic effect of selected plant species (dominants which appear during the first year following clean cuttings of Scots pine (Vacciniosa) forest) on Scots pine (Pinus sylvestris  L.) seed germination and seedlings development as well as to reveal whether the effect is dependent on temperature (day / night) regime conditions. Aqueous extracts of Pleurozium schreberi, Vaccinium vitisidaea and Calluna vulgaris were tested. The effect of ground parts and roots was analysed.
The extracts exerted stronger phytotoxicity on germination of Scots pine seeds at 20 °C/29 °C than at 18/27 °C temperature regime. The inhibitory effect of the plant species and plant parts tested was stronger on radicle growth than on hypocotyls growth both at 18/27 °C and 20 °C/29 °C temperature regime.
