THE PHYSIOLOGICAL BASIS OF ADAPTATION OF A PLANT SPECIES IN URBANIZED ENVIRONMENT

Kutafina N.V., Krasnopivceva A.N.

Abstract

Plants, the leading fixed way of life, are forced to be particularly plastic on environmental impact responses of the environment. The most important external factors include the light, which is not only a source of energy for photosynthesis, but also a signal, activating and changing the program of development of the plant. Objective: To study the content and ratio of different forms of photosynthetic pigments in leaves of plants that grow only in natural light (forest) and compared to individuals present in the conditions of an additional light (located near the street lamps and lighted windows of houses). The experience included birch specimens of plants growing in a forest tract Gutorevo (dense stands of birch within the pine forest) and tree planting ordinary Lear Park (southern suburbs of Kursk area). The leaves are weighed. pigment content was determined by in vitro analysis in four replicates. The content of chlorophylls and carotenoids were determined by calculation. Volume fraction pigments evaluated. Statistical analysis were Student t-criterion. The content of chlorophyll and carotenoid in the leaves of birch in an artificial increase in the duration of the light period in the temperate climate of the Kursk region. In plants, an increase of chlorophyll content (a + b) 12.0% of carotenoids in the leaves 23.0%. There is reason to believe that the adaptation of the pigment apparatus birch plants growing under natural light (forest) and located in the area of artificial lighting is done by transforming the light-harvesting complex. Factor complex urban environment, including sunlight, soil compaction podkronovogo space in which increasingly suffering park biome, does not reduce the content of pigments in the end of the growing season, in comparison with individuals forest biome. This testifies to their high stability and better adaptation to the effects of natural and anthropogenic factors.

THE PHYSIOLOGY OF PHOTOPERIODIC SENSITIVITY AMONG PLANT SPECIES WITH DIFFERENT LIGHT PERIOD

Zubkova E.N., Belova T.A.

Abstract

The most important characteristic of the environment for vegetable organisms is the photoperiod - duration of daylight. Plant Responses to the day length (photoperiod conditions) is of great importance in the development of environmental monitoring, providing the necessary spatial and temporal regulation of physiological processes in plants and optimizing the processes of photosynthetic activity. Objective: To estimate the photoperiodic sensitivity of samples of Raphanus sativus, and to identify his reaction to the increase in the length of daylight hours in conditions of Central Black Earth region. Change the duration of daylight is largely affects the development of plants. In terms of the long lightday photoperiodic sensitivity radish Raphanus sativus in the Kursk region is manifested in the increased growth of above-ground parts of plants and development of the generative organs. When growing radishes in the Kursk region in the conditions of artificially shortened daylight hours the plant for a long time remained in a vegetative state. It is clear that the formation of the major root crops of radish with good taste must be his growing under short photoperiod. The best planting time for the Central Black Earth zone - the end of March-April and the end of July-August, when the daylight hours of about 10 hours. When growing plants during the long daylight crops is necessary to create an artificial shading.

PHYSIOLOGICAL ASPECTS OF PLATELET-DERIVED ACTIVITY IN CALVES FIRST YEAR OF LIFE IN THE CENTRAL BLACK EARTH

Kutafina N.V., Belova T.A.

Abstract

Optimum functional characteristics of the whole speaker largely regulated hemostasis vascular functional activity of blood cells, including platelets. Hemostasis seriously determines the state of blood rheology level of flow to tissues, metabolism in the heart muscle, a condition of resistance to infections, growth processes in the musculoskeletal system in health and disease and in a corrective interference. The goal - to find out the dynamics of the parameters of platelet function in healthy calves during the first year of life. Examination was carried out on healthy calves: 67 newborn animals, 22 calves aged 30 days, 21 Calf aged 3 months and 23 years of age in the animal. We used biochemical, hematological, and statistical methods. Platelet aggregation with all inductors calves remained stable for the newborn. At older ages, it was growing, reaching maximum values for the year. The found regularities confirmed intravascular platelet activity. Number of active forms of platelets after the neonatal phase gradually increased, reaching a peak-to-year life. During the early ontogeny of calves on the background of their growth increases platelet activity, which increases the number of activated forms in the bloodstream, helping to increase the amount of freely circulating units, which is important adaptive value in response to environmental effects on the animals.

HEMOSTASIS SYSTEM IN LACTATING COWS IN THE CONDITIONS AVERAGE VOLGA REGION IN NORMAL AND EVENTS BEGINS MASTITIS

Zaitsev V.V., Grigoriev V.S., Makurina O.N.

Abstract

Hemostatic system - this is an important mechanism for maintaining hemostasis. At the same time, particularly hemostatic system in healthy active lactating cows with mastitis beginning are not completely clarified. The goal - to find out the level of functional activity of hemostasis in cows in mid-lactation in norm and in conditions of incipient mastitis. Investigations were carried out on 61 cow calving 3-4 contained in the conditions of the Samara region. Of these, the control group consisted of 24 healthy cows and 37 cows with signs of incipient mastitis amounted experimental group. The paper applied hematologic and statistical methods. Based on literature data, it is clear that breastfeeding affects the intensity of the hemostatic process. The paper found that in mid-lactation cows healthy there is a weakening of activating effects in hemostasis and increased fibrinolysis mechanisms. This leads to the maintenance of their optimum rheological properties of blood, ensuring delivery of the required amount of nutrients and oxygen to all the organs and tissues, promoting the rise of milk production. In the case of inflammation of the mammary gland in cows come changes in the hemostatic system activities that form the propensity to thrombosis. Developing their hemostatic activation is associated with simultaneous strengthening of its plasma and platelet units. It becomes clear that in lactating cows in the early development of the terms of mastitis occurs strengthen hemostatic mechanisms.
