MORPHOLOGICAL AND CYTO-BIOCHEMICAL BASIS OF SHOOT FORMATION OF CEREALS
DescriptionProcess of shoot formation of cereals is associated with the formation of zone shortened internodes, establishes buds certain capacity and completes transition by growth and formation of crop aboveground mass of each individual. Process of shoot formation is divided into three phases - preparatory, hidden and visible tillering, each of which is different peculiar morphological and cytobiochemical development

Description
The pathogenic agent of apple scab disease, Venturia inaequalis (Cooke) Winter, causes significant damage to the industrial production of apples. Studying the pathogen in pure culture is important for solving the theoretical and practical issues of its biology. The sporulation ability of the Venturia inaequalis laboratory culture is an important diagnostic feature in morphological culture analysis, in the test for sensitivity to fungicides, when creating a collection inoculum for an artificial infection. We have studied the morphological features of conidiogenesis of pure V. inaequalis culture, such as the location of conidiogenic structures and their form. For the first time in the laboratory culture of the pathogen, sporulation in the thickness of agar on the substrate mycelium was demonstrated. Conidiogenesis proceeded according to the blastic-annellidic type. Depending on the location of the conidiogenic structures on the aerial or substrate mycelium, their morphology was different. Conidiogenic areas in the substrate mycelium could be observed with the unaided eye, in the form of hyphal grit, while they were conidia conglomerations in each annelid. Annellide had a curved shape. On the aerial mycelium, annelids were straight and always had only one conidium. Differences in the morphology of conidiogenic structures are supposed to be related to the physical conditions of the environment in which sporulation takes place. In the agar, each mature conidium remaining at the apex of the annelid interferes with the formation of the next one, which results in its bending. The fixed arrangement of conidiogenic structures and forming conidia in the thickness of agar allows the use of substrate sporification for model studies of the conidiogenesis process

MORPHOLOGICAL AND ANATOMICAL STUDIES OF TRIPLOID FORMS OF ASPEN
DescriptionIn this article, we have presented the survey of populations of triploid plant of Populus tremula L. genetic reserve of aspen in the area of Sharinsk in the Kostroma region. We have found the population of P. tremula L. not affected by the Phellinus tremulae Bond. et Boris fungus. The morphological and cytological analysis of plant samples taken from this genetic reserve in 1961 has been made. It has finally confirmed the triploid nature of the samples

MORPHOMETRIC ANALYSIS OF LEAF AMPELOGRAPHIC INFORMATION
DescriptionModern ampelography has reached the newest level of usage of the latest achievements of multimedia techniques and computing means of handling and analysis of assembled information. An adult leaf is a sort of "passport" of the breed, and the most important significance among set of descriptive characteristics is attached to it. For decrypting of the numeral information of leaves, it is offered to use SIAMS company toolkit, in particular - the SIAMS MesoPlant analyzer. In this article, the technique of reading (decrypting) of a leaf ampelographical information from alive and dry samples and the biometric analysis for level of morphotypical establishment of objects of researches is resulted

MORPHOMETRY OF LEAVES OF THE KUBAN WILD-GROWING LIANAS OF GRAPE
DescriptionThe morphometry of leaves of the Kuban wild-growing lianas of grape, as we know, is not learnt till now and availability of quoters of pure subspecies of Vitis vinifera silvestris Gmel is not demonstrated., though suppositions about this information soared in the scientific environment as old as Adam [5]. With the advent of a direction of morphometry taxonomy there was a necessity of accurate bracing of a current state of a genotypical diversity of lianas and biological polymorphism of leaves for link establishment silvestris - silvesatis - sativa

WAYS OF TECHNOLOGICAL ADVANCEMENT THERMAL TREATMENT OF OIL-CONTAMINATED WASTE
DescriptionThe article deals with the problem of oil-contaminated waste neutralization by thermal method. A comprehensive analysis of the original waste going for recycling and the resulting ash and the assessment of eco-toxicant migration in the environment are carried out. It is suggested the measures for resource saving to get secondary material resources and recommendations for improving thermal destruction technologies consistent with the requirements to the best available techniques

NEW ADVENTIVE WEED PLANT AMMANNIA COCCINEA Rottb. IN THE RICE FIELDS OF THE KRASNODAR REGION
DescriptionRice fields all over the world are one of the places of invasion of adventive weed species. They can reduce the yield of the rice crop by 20-30%. The phytomonitoring studies in the rice systems of the Krasnodar region in 2017 have discovered a new species of Ammannia coccinea Rottb. (Lythraceae) among the weed vegetation of the grain crops. The article gives a botanical description of the species; its biological and ecological features and ways of its distribution are discussed. Ammannia coccinea is an annual plant, light-loving and hygrophilous. The country of origin is North America. This is one of the most malicious weeds in California and the United States in general. In Asian and European countries, the plant is brought with rice seeds. Currently, in many rice-growing regions of the world, the species A. coccinea tends to spread and increase the severity of infestation. The species was registered in the Krasnodar region in the rice fields of the Abinskiy, Kalininskiy, Krasnoarmeiskiy and Slavyanskiy regions. The number of plants of A. coccinea does not exceed one plant per 10 m2, with the exception of three locations of invasion, where the density is up to 5-7 pcs/m2 and the plants occupy an area about 0.5 hectares. Considering the fact that in rich soils the height of the plant reaches 1 m, with the ramification of the stem, the plants go to the first tier. They successfully compete with rice plants, suppressing their growth and development. This can adversely affect crop yield. The article discusses the reasons for the appearance of A. coccinea in the rice fields of the Krasnodar region
