The purpose of research is to evaluate the effect of pre-planting treatment of potato tubers with cell saps obtained by microwave hydrodistillation from Siberian indigenous plants on growth parameters during yarovization. Objects and methods. The studies were carried out in the laboratory of the Institute of Space Technologies, Krasnoyarsk Scientific Center SB RAS in January–February 2026. Cell saps were obtained from Siberian fir (Abies sibirica), fireweed (Chamerion angustifolium), winter horsetail (Equisetum hyemale), common aspen (Populus tremula) and anomalous peony (Paeonia anomala) using a laboratory microwave unit [6]. Chromatographic analysis (Milichrom A-02) confirmed the complex composition of the saps, including compounds absorbing in the UV region (phenolic acids, flavonoids). Potato tubers of the Krasa Meshchery variety (5 pcs. per variant) were soaked in 5 % sap solutions (control – water) for 2 hours, then germinated for 40 days at 18 °C, the first 30 days – in natural light, then in the dark. The number of awakened eyes, average sprout length, total number of roots and total root length were recorded. The significance of differences was assessed using the Mann–Whitney U test. Results. The greatest stimulating effect was found in fireweed: the average sprout length increased by 87 % (up to 14.4 mm), total root length – by 4 times (up to 393 mm) compared to the control (p > 0.05 due to high variation). Horsetail significantly (p < 0.01) increased the number of sprouts (2.4 pcs. vs 1.4). Aspen showed an inhibitory effect (total root length decreased by 7.3 times, p < 0.05). Fir and peony did not significantly affect growth. Conclusion. Fireweed cell sap is promising as an environmentally friendly biostimulant for pre-planting treatment of potatoes, and aspen cell sap – as a natural germination inhibitor during storage, which corresponds to the objectives of the National Project “Technological Support for Bioeconomy”.
