Вплив лазерного опромінення насіння на ростові процеси та вміст пігментів у проростках олійних культур

Abstract

Introduction. According to the research of many authors Laser preplant seed treatment may promote germination, accelerate the germination of seeds, the initial stages of growth and development of plants and further increase the resistance of plants to diseases that positively affect their performance. However, the use of laser systems is limited by their size, significant power consumption for low power beams of radiation. Therefore, we studied the effect of laser irradiation on seed growth processes of plants in the early stages of growth and pigment content in seedlings of oil crops using energy-efficient laser systems red and blue light. Methods . Purpose was to investigate the influence of laser irradiation on the growth processes and content of pigments in seedlings of some oilseeds. For the purpose solved such problems - to study the effect of laser irradiation on germination and sprouting seeds to analyze the initial stages of plant development and determine the content of chlorophyll a and b spectrophotometric method. The objects serve the following plants: sunflower normal ( Helianthus annuus L.), winter rape ( Brassica napus L.) , white mustard (Sinapis alba (L.) Rabenh. ). The study took place 2015-2016 years. Irradiation of seeds was carried out by red LED laser (635 nm) and blue (405 nm) light with a capacity of 100 MW. Results and discussion . Studies indicate positive effects of laser irradiation on the initial stages of plant development. Proven positive effect of red light on growth indicators studied aerial parts of plants. Also of note is the positive impact of blue laser on root growth of plants studied species. Proved ineffective triple exposure test plants. All we studied oleaginous set a positive effect of exposure on the content of chlorophyll a and chlorophyll b.
