The pre-sowing treatment of seeds with electromagnetic radiation belonging to different parts of the spectrum is one of the promising areas of research. In accordance with the data presented in scientific publications, infrared and ultraviolet radiation contribute to an increase in seed germination, intensity of plant development, yield and resistance to adverse effects of various nature. It also has a beneficial effect on the biochemical composition of fruits and their storage stability. There are some contradictions between the results of various studies, this is why the problem deserves further research. This work examines the effect of infrared radiation of a ytterbium laser on the morphological signs of the germination of seed material of agricultural crops. Three optical schemes of the experi-mental setup are suggested and calculated. Two of them have been implemented and used to achieve the objectives of the study. The influence of laser radiation with a wavelength of 1080 nanometers on the germination of seeds of eight plant species and the moisture absorption of six species was studied. Different treatment duration and different radiation power were considered. The data obtained do not allow to draw unambiguous conclusions about the effect of infrared laser treatment on seeds germination. An increase in the irradiation duration tends to worsen the germina- tion result. Generally, such treatment positively affects moisture absorption, however, very weakly. An increase in the duration and power of irradiation leads to a decrease in moisture absorption.","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"164 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123834321","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The territory of the Iraqi part of the Tigris-Euphrates interfluve, especially in its southern part, is characterized by the spread of such a type of soil degradation as salinization due to the use for many centuries of fertile alluvial soils for growing various crops using irrigation systems. The conducted geoinformation analysis of the degradation of agricultural landscapes allows for operational monitoring of their condition, determination of the spatial position of degraded areas, identification of the conditions for the functioning of each field and provides an effective basis for taking measures for economically justified work on growing crops. The results of mapping agrolandscapes in Maysan province and assessing their degradation made it possible to establish the features of its relief for the test site, as well as the spatial distribution of agricultural land plots according to the degree of degradation. It was revealed that on the area of the test plot (196 ha) there are 59 fields with an area of 122 ha, of which 5 are not used due to severe soil salinity (total salt content is more than 3%). The predominance of agricultural land, arable land and gardens, occupying 69% of the study area, was established. When assessing land degradation, it was found that the largest area (64.4 ha) is occupied by lands with very strong and strong salinity, taken out of use and overgrown with ruderal vegetation. Lands with a degradation level of «risk» occupy 45.8 hectares, with a level of «crisis» – 20.6 hectares, with a level of «disaster» – 64.4 hectares.","PeriodicalId":246793,"journal":{"name":"Успехи современного естествознания (Advances in Current Natural Sciences)","volume":"37 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"1900-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124017126","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
