Melilotus Albus

Melilotus is an important genus of legumes with industrial and medicinal value, partly due to the production of coumarin. To explore the genetic diversity and population structure of Melilotus, 40 accessions were analyzed using long terminal repeat (LTR) retrotransposon-based markers. A total of 585,894,349 bp of LTR retrotransposon sequences, accounting for 55.28% of the Melilotus genome, were identified using bioinformatics tools. A total of 181,040 LTR retrotransposons were identified and classified as Gypsy, Copia, or another type. A total of 350 pairs of primers were designed for assessing polymorphisms in 15 Melilotus albus accessions. Overall, 47 polymorphic primer pairs were screened for their availability and transferability in 18 Melilotus species. All the primer pairs were transferable, and 292 alleles were detected at 47 LTR retrotransposon loci. The average polymorphism information content (PIC) value was 0.66, which indicated that these markers were highly informative. Based on unweighted pair group method with arithmetic mean (UPGMA) dendrogram cluster analysis, the 18 Melilotus species were classified into three clusters. This study provides important data for future breeding programs and for implementing genetic improvements in the Melilotus genus.

Trifolium Pratense L

В последние годы в Пермском крае прекратилось известкование кислых почв, недостаточно вносятся минеральные и органические удобрения. Всё это постепенно привело к снижению плодородия почв. Избежать или снизить влияние негативных явлений можно за счёт использования многолетних трав. Перспективной фитомелиоративной культурой является эспарцет песчаный (Onobrychis arenaria (Kit.) Ser.), который ранее в Пермском крае не возделывался, но встречается в естественных фитоценозах ряда районов края. Целью настоящей работы является поиск и обобщение научной информации по морфо-биологическим особенностям и агроэкологической роли эспарцета песчаного в земледелии. В статье приведён литературный обзор биологических особенностей этой культуры: азотфиксации, накопления пожнивно-корневых остатков, формирования корневой системы эспарцета песчаного в различных регионах его возделывания. Для сравнения приведены экспериментальные данные ряда исследователей, полученные в Пермском крае при изучении клевера лугового (Trifolium pratense L.), люцерны изменчивой (Medicago×varia Mart.), донника белого (Melilotus albus Medik.). Эспарцет песчаный за счёт корневых выделений способен усваивать из глубоких горизонтов почвы труднодоступные для других культур кальциевые и фосфорные соединения и обогащать ими верхний горизонт почвы, то есть он может выступать в роли биологического мелиоранта. На опытном поле Пермского НИИСХ эспарцет песчаный изучался с 2011 по 2019 год и зарекомендовал себя как перспективная кормовая культура. Изучение его особенностей с целью разработки технологий возделывания и использования целесообразно продолжить и расширить. Over the last years, liming of acidic soils stopped in the Perm Territory; mineral and organic fertilizers are not applied sufficiently. All this gradually led to a decrease in soil fertility. It is possible to avoid or reduce the influence of negative factors by planting perennial grasses. Hungarian sainfoin (Onobrychis arenaria (Kit.) Ser.) is a promising phytomeliorative crop for the Perm Territory. It was not previously cultivated there, but it is found in natural ecosystems in a number of locations. The investigation aimed at reviewing morphology, biology and ecological value of Hungarian sainfoin. The article deals with its biological features: nitrogen fixation, accumulation of crop residues as well as root system formation in various regions. To compare sainfoin with other crops in the Perm Territory, the article provides the experimental data on red clover (Trifolium pratense L.), alfalfa (Medicago×varia Mart.), and white melilot (Melilotus albus Medik.). Due to root secretions, Hungarian sainfoin is able to assimilate calcium and phosphorus from deep soil that are unavailable for other crops. So, the crop can enrich the upper soil layers with these elements, being a biological ameliorant. Studied during 2011–2019 on the trial field of the Perm Research Institute of Agriculture, Hungarian sainfoin was shown to be a promising forage crop. Its further investigation as well as development of efficient cultural practices is of high value.

Enhancing of soil fertility is required for getting high yields from cotton plant, cereals and other crops in Uzbekistan. It may be achieved through implementation of crop rotation, properly introduction of rotation and by the planting of kashkar beda, alfalfa and other bean bearing crops. Planting of Kibray variety of Kashkar beda in strongly salted areas and may be produced high yields than ordinary blue alfalfa. It’s an average green mass yield accounts for 4.0-4.5 tons per hectare, 1 kg green mass contains 17-25 g protein and 0,16-0,20 food units what is a nutritious food for agricultural animals. Beside this, due to its root nitrogen-fixing capability. It may be taken durable high yields from other crops in its planted area.

The purpose is to determine the productivity of perennial legume and cereal grasses under conditions of natural moisture supply in South Steppe of Ukraine. Method. The studies were conducted during 2016—2018 using conventional methods, and the output of feed units, digestible protein per unit of area was determined by reference books. Results. On average over three years of research, the highest yield of leaf-stem mass of cereals was formed by Bromus inermis and Elytrigia medium tender – 11.6 and 11.2 t/ha, respectively. The lowest yield was formed by Agropyrum pectiniforme – 7.6 t/ha. Among the all legume grasses, Melilotus albus prevailed (14.8 t/ha). Medicago sativa and Onobrychis arenaria were able to form a similar yield (14.5 and 13.5 t/ha, respectively) under the arid conditions of South Steppe of Ukraine. Insufficient rainfall in 2017 caused a decrease in the productivity of the studied crops. Thus, in 2017 the average yield of green mass in the experiment was 10.3 t/ha, while in 2016 under more favorable weather conditions this figure was 13.2 t/ha or 28.2 % more. The highest output of feed and protein units (FPU) per unit of area under cereal grasses was provided by Bromus inermis (2.35 t/ha). The lowest one was recorded in Agropyrum pectiniforme (1.60 t/ha). FPU output per unit of area under legume grasses increased respectively. Lotus corniculatus provides less green mass and therefore dry matter and forage and protein units. Perennial cereals grasses do not prevail over legume grasses, so they do not spread in South Ukraine. Conclusions. The productivity of perennial grasses in the south of Ukraine significantly depends on the type of plants, weather (hydrothermal) conditions of the year. The most effective is the cultivation of perennial legumes, namely Melilotus albus, alfalfa, Onobrychis arenaria. Bromus inermis and Elytrigia medium prevail among cereal grasses.

A comparative analysis of leaf blades of two kinds of clover (Melilotus albus, Melilotus officinalis) growing on the territory of Kalmykia has been carried out. Identified diagnostic features in the anatomical structure of the leaves of each species. The parameters of leaf tissue are set. The results of the work give an idea of the degree of plasticity of a characteristic of a leaf plate of two types of clover. Demonstrated features of plates of the same species can be equally, as well as specific for this species, and adaptive variability, due to which the plant has adapted to life in arid conditions. The water regime, indicators of transpiration and productivity of the clover were studied. Changes in physiological parameters were determined before the onset of the summer drought and at its height. The established morphological and physiological characteristics of the two species of clover allow them to be defined as plants that are well adapted to growing under the arid conditions of Kalmykia. The combination of the structural features of the clover with its physiological capabilities, valuable feeding properties and a positive effect on the soil, testifies to the effectiveness of the use of clover in the lean, saline areas of the region. The obtained data can be used in further systematic studies of the genus Melilotus, as well as in planning reclamation measures.
