“…Among the studied cultures, there was not a single breed that did not respond to laser irradiation to some extent. For example, the field germination was increased for Crimean pine and sycamore by 10%, Robinia, Catalpa, and Cercis by 20%, and black walnut by 36% (Maksimenko et al 2020). Laser treatment of seeds increased the germination of rhododendron seeds 2-4 times (Skvarko 1997), as well as the weight and length of shoots of Caragana, Gleditsia, and Robinia (Aladjadjiyan 2003).…”

The success of forest and agricultural plant establishment program mainly depends on the quality of reproductive material. The study intends to offer engineers and farm owners a solution for small-size seed improvement before sowing. The effect of low-intensity coherent light on the seeds of various crops is theoretically and empirically hypothesized. The seedlots of Scots pine (Pinus sylvestris L.) and sugar beet (Beta vulgaris L.) of Russian diploid hybrid RMS-127 were germinated in a controlled environment. The germinants were produced from six seed fractions, previously irradiated with 1.274 W·m<sup>–2</sup> at the 632.8 nm wavelength with 1, 2, 3, 5, 10, 15 min exposure to a standard laser system, plus untreated control. Pine germinants were measured on day 15, beetroot on day 10 after germination. An increase in exposure time reduced Scots pine germination energy and capacity, while for sugar beet the results were not conclusive. On the contrary, increasing the exposure time had a positive effect on both the height and biomass growth of both Scots pine and sugar beet germinants. The 10-min exposure time resulted in maximum values for sugar beet height and biomass and Scots pine height, while the 15-min exposure time produced maximum Scots pine biomass.

На основе анализа изменения числа и длины микропобегов микрорастений малины Оранжевое чудо и ежевики Black Satin была проведена оценка эффективности различных приемов лазерного воздействия на растения в культуре in vitro. Цель исследований заключалась в оптимизации параметров лазерного воздействия, обеспечившего минимальное энергопотребление и максимальный стимуляционный эффект. Для проведения экспериментов была разработана компьютеризированная лазерная установка, позволяющая создавать режим непрерывной, импульсной и сканирующей засветки любой длительности и периодичности. Показано, что наибольшее (двукратное) увеличение ростовых показателей может быть получено при использовании серии коротких (1; 7,5 с) импульсов когерентного света. Based on an analysis of changes in the number and length of shoots of microplants of the Orangevoe Chudo raspberry and Black Satin blackberry, the effectiveness of various methods of laser irradiation on plants in vitro culture was assessed. The goal of the research was to optimize the parameters of laser exposure to ensure maximum energy efficiency and sufficient stimulation effect. To carry out the experiments, a computerized laser device was developed that allows creating continuous, pulsed and scanning illumination modes of any duration and frequency. It is shown that the greatest (twofold) increase in growth rates can be obtained using a series of short (1; 7.5 s) pulses of coherent light.
