Влияние низкочастотного электромагнитного поля на лабораторную всхожесть семян и выход сеянцев сосны обыкновенной (Pinus sylvestris L.)

Abstract

The results of research that was conducted in 2017 in the laboratory of the Department of Forest crops, breeding and dendrology of the BMSTU (Mytishchi branch) and in the Pravdinsky nursery of the Pushkin forest technical College of the Moscow region. The purpose of the study was to determine the effectiveness of the influence of low-frequency electromagnetic field (EMF) on laboratory and ground germination of common pine (Pinus sylvestris L.) seeds with low seeding characteristics. Samples of common pine seeds of the 3rd quality class were selected for the study (collection 2014). The seeds selected for the study were treated with low-frequency EMF using POSEP technology (pre-sowing seed treatment with an electromagnetic field) with a low-frequency generator Rost-Active. One part of the seeds was laid for germination in the laboratory in 4-fold repetition, the other was sown in the sowing Department of the Pravdinsky nursery in 3-fold repetition, control was served by unprocessed seeds. As a result of pre-sowing treatment of pine seeds, laboratory germination exceeded the control by 25 %, and approached the indicators for class I seeds. In the Pravdinsky nursery, the yield of 1-year-old seedlings increased by 16 %, and their height was 47 % higher than the control. The results of laboratory and field studies have demonstrated the high efficiency of pre-sowing treatment of common pine seeds using POSEP technology and its ability to restore the seed quality after long-term storage, increase the yield of seedlings and improve their biometric indicators.
