The inheritance of the “mass of 1000 grains” sign in the hybrids F1 and F2 was studied. Differences in the parental forms with 1-5 pairs of genes are revealed. The sources and the donors of the large-mass of grain are pointed, the indicative and genetic collections of the large-mass of grain forms of the grain sorghum are created
The stem form pathology, which causes the limited life – durability and pre-mature death of the tree is described. The stem form pathologies as well as the percentage of their occurrences, depending on specific factory (age, stand degree, tree origin, land form), are reviewed
There was determined that the heat resistance of fruit and decorate plants depends not only on their morpho-biological peculiarities but on the specific of temperature stressor revealing in corresponding years. There were selected three types of influence of high air temperature on plants on plants during summer period and three components of heat resistance respectively. There were cited possible mechanisms of plant adaptation to overheat. There were cited diagnostic criteria of their heat resistance
There were presented the results of bumblebee application for obtaining of hybrid seeds of tomatoes
The article shows the parameters of changes in microclimatic and soil conditions of interbelt cells in the system of field protection plantings
The article proposes a system of regression equations to
estimate the parameters of the normal probability distribution of the number of trunk diameters in stands of oak plantations of Lower Volga. Commodity tables for estimation of forest stands are developed
The results of studying of growth, fattening and meat qualities of marketable grosses from large white, Landras and Dyurok breed crossing have been cited in the article. Optimum pig weight when early weaning was established
The features of milk production of Holstein Friesian
imported heifers to Krasnodar region from Germany with a view of linear supplies and their ancestors on the main indicators of productivity and breeding value are shown. A comparative analysis of the productive qualities of the German Holstein-Friesian with Black Pied cattle domestic breeding is made. The ways of the effective use of the Holstein Friesian German-breeding to create a highly productive dairy cattle herds in the North Caucasus are outlined
The results of the experiment to study the influence of aromatic additive “Caramel-Vanilla” at the killing indicators of pigs of large white breed are presented in this article. It is established that the cultivation and a fattening of pigs when adding this aromatic additive to animal feed is an effective technique. The use of aromatic additives in rhythm input: 10 days with the addition of 10 days without it until the end of fattening positive impact on feed intake, growth, and the payment of his live weight gain of pigs. The live weight of animals for the period of experiment (123 days) increased by 8.6 % compared with the control
The analysis of fruit crops saplings production in the Krasnodar region is presented. The problems of the modern fruit crops saplings production in the region are allocated and possible ways of decision these problems are given
