La cercosporiose due à Cercospora oryzae est un champignon pouvant causer des pertes allant jusqu'à 60%. Elle est de plus en plus fréquente en Afrique de l'Ouest. Les premières prospections réalisées au sud du Bénin ont indiqué que Cercospora oryzae a une contribution large puisqu’elle a affectée 85% des champs de riz des trois zones agroécologiques du sud Bénin. Cette étude vise principalement à contribuer à la connaissance détaillée des effets de Cercospora oryzae sur les grains afin d’optimiser la conservation, la commercialisation et la production. Elle a consistée a : i) évaluer les effets de Cercospora oryzae sur le pouvoir germinatif des grains, ii) évaluer les effets de Cercospora oryzae sur le développement de la ternissure. L’étude a combiné des outils physiologiques et phytiatriques. Au terme des travaux, les variétés testées ont enregistré une bonne teneur en eau pour un minimum de 6%, ainsi qu’un bon taux de germination. A la fin de l’étude nous avons pu constater que Cerocpora oryzae entrainait une baisse du pouvoir germinatif des grains, une altération de la graine blanche et une décoloration de l’enveloppe. Ces résultats constituent une étape d’un travail de recherche approfondi sur la caractérisation (agronomique et génétique) de Cercospora oryzae afin de proposer des méthodes de luttes. Mots clés : Pouvoir germinatif, décoloration, altération, Cercospora oryzae, riz.   English Title: Study of the effect of Cercospora oryzae Miyake on the quality of rice grains and the development of tarnishSigatoka caused by Cercospora oryzae is a fungus that can cause losses up to 60%. It is more and more frequent in West Africa. The first surveys carried out in the south of Benin indicated that Cercospora oryzae has a large contribution since affected 85% of the rice fields of the three agroecological zones of southern Benin. The main objective of this study is to contribute to detailed knowledge of the effects of Cercospora oryzae on grains in order to optimize conservation, marketing and production. It consisted in: i) evaluating the effects of Cercospora oryzae on the germination power of the grains, ii) evaluating the effects of Cercospora oryzae on the development of tarnish. The study combined physiological and phytiatric tools. At the end of the work, the varieties tested recorded a good water content for a minimum of 6%, as well as a good germination rate. At the end of the study we could see that Cerocpora oryzae did not cause a drop in the germinative power of the grains but rather resulted in an alteration of the white seed and a discoloration of the envelope. These results constitute a stage of an in-depth research work on the characterization (agronomic and genetic) of Cercospora oryzae in order to propose methods of struggle.Keywords: Germination, discoloration, deterioration, Cercospora oryzae, rice.

Safety of milk on microbiological indicators is an important condition for acceptance on the milk processing enterprise. High microbial contamination of milk and increased content of somatic cells in milk are often the cause of discrepancy to modern requirements of national and international regulatory documents. The development and implementation of measures aimed at improving the condition of the udder of cows, the use of modern means of processing is one of the most important tasks to improve the sanitary and hygienic conditions of milk production. Prevention of mastitis is one of the effective ways to improve the safety and quality of cows' milk. It is known that the most affordable way to prevent mastitis is strict hygiene during milking. In our article the results of research work received in the conditions of a dairy farm are presented. Researches on use of modern domestic means of processing of an udder before and after milking are carried out. For this, two experimental and one control groups were created. In summer and autumn, the udder of cows in the experimental groups were treated with special detergents and disinfectants. In the control group, the udders were not treated with special means. Udder hygiene was maintained by washing the nipples with warm water, as is customary in the household. It was established that the treatment of the udder of cows with disinfectants decreased the number of mesophilic aerobic and facultatively anaerobic microorganisms and somatic cells in the milk of cows.

ABSTRACT Physalis is represented by species that produce fruits with relevant potential for national and international marketing. The species are normally grown from seeds, so maturation studies are important to assist the point of harvest, as well as seeds with a high physiological potential, since the fruits remain enclosed within a cup throughout their development. Despite the nutraceutical importance of fruits and medicinal potential of many species of Physalisinformation on the physiological seeds quality are scarce. This study aimed to monitor the physical and physiological changes of maturation and the viability of seeds during fruit development stages. The fruits of P. ixocarpa were collected in 15, 25, 35, 45, 55 days after anthesis (DAA). Length, diameter, fresh weight, skin and cup coloring characterization, TSS content, number and weight of seeds per fruit were obtained at each development stage. We also evaluated and correlated the coloring and pigment content of the cup (chlorophyll a and b). Water content, dry matter weight and germination rate were measured from fresh and dry seeds (room conditions, 72 hours). The main physical and physiological changes during maturation occurred within 35 DAA. The maximum physiological seeds quality was achieved within 45 DAA when the cup is completely or partially broken with coloring between yellowish-green and light-yellowish-brown and the ripe fruit in dark-green.

This chapter challenges traditional views on Iron Age dress. Recent research has greatly enhanced our understanding of how textiles were manufactured in Iron Age Europe. The variety of qualities, textures, techniques, raw materials, colours, and cuts give insights into the detailed knowledge of the craftspeople involved. Textiles used for dress, blankets, or furniture fittings were appreciated not only for their appearance, but also for the quality of the work. In everyday life, their optical qualities were used to express and signal gender, social roles and status, while the labour expended on textiles found in wealthy burials underlines both the status of the deceased and the extent of conspicuous consumption in funerary rituals—for instance, for wrapping grave furniture and goods. The chapter also looks at experimental data showing how labour-intensive textile production was, and the types of clothing and accessories found in different archaeological contexts or depicted in visual representations.

Purpose This study aims to discover the motive for the time-to-time Hellenic collective capitalists’ intervention in the total circulation of capital of public works throughout the relative legislative framework. Thus the study attempts an original correlation of statistical indicators of Hellenic Statistical Authority with the legislative texts. Design/methodology/approach The Hellenic truth is that the branch of public works presents a peculiarity as far as the volume and quality of statistical facts and figures are concerned. To overcome this obstacle, this study analyzed the change of time series, relating the procedure of total circulation of contracting capital involved in public works with the content of the relative legislative rules which were applied during the period of 1958-2004 and their preambles. In this way, the annual volume of the constructional product in general is directly related with the particular characteristics that define the procedure of total circulation of the contracting capital in general. Findings The directly relation between the annual volume of the constructional Product in general and the particular characteristics that define the procedure of total circulation of the contracting capital in general, leads us to conclusions which, related with the policy and practices adopted by the collective capitalist, confirm or even set off eventual failures of respective conclusions drawn according to the prevailing concept. Originality/value By introducing the technique, the aim of this research work is achieved without reproducing the method of study and the conclusions of other researchers.

Purpose: to analyze the experience of Russian scientists in the field of application of a differentiated approach to agricultural crops irrigation. The overview of research work of domestic scientists on the use of an irrigation system in agriculture, in which the provision of agricultural crops with water to maintain a given level of the minimum water capacity will be carried out during the most critical periods of their growth and development is presented. During irrigation, the timing, frequency, irrigation rates depend on the level of groundwater occurrence, agrochemical properties of soils, weather and climatic conditions, phases of growth and development of crops. The application of a differentiated irrigation regime to maintain a given level of pre-irrigation moisture allows increasing the productivity of agricultural crops, the quality of products obtained while reducing irrigation and watering rates, the number of waterings. Conclusions. The study of the results of research work of domestic scientists in the field of influence of irrigation and the fertilization system on the yield and quality of agricultural products allows concluding that obtaining the planned yields is possible only if irrigation regimes are observed and the level of soil fertility is maintained by applying various fertilizers. The use of a differentiated approach to irrigation while maintaining a given level of pre-irrigation soil moisture during critical periods of crop development allows reducing irrigation water consumption and optimizing irrigation rates and their quantity. The study of a differentiated irrigation regime is promising now and in the near future, taking into account the deteriorating water supply in the territory of our country, associated with a change in weather and climatic conditions.

Carrot seeds exhibit irregular vigor due to the wide blooming period of the crop. Results from germination tests are insufficient to evaluate the physiological potential. Thus, vigor tests are used in combination with germination tests. The objective of this work was to evaluate the quality of carrot seeds from different umbel order and the electrical conductivity under different temperatures and imbibing periods. Carrot seeds from cultivar Brasilia were used to perform the experiments. Content of water, the first and the final score of the germination test, index of germination rate, and length of roots and of the aerial portion were determined in the initial characterization. The electrical conductivity test was completed with replicates containing 50 seeds, in 25 mL deionized water at 20, 25 and 30oC. Evaluations were performed with 2, 4, 6, 8, 12 and 24 hours of imbibing period. The experiment was accomplished under a completely random statistical design. The quality of carrot seeds varied according to the umbel order. Seeds of secondary umbels showed better physiological quality. The electrical conductivity test is efficient to evaluate the vigor of carrot seeds with 8 hours of imbibing period at 25°C.
