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

BIOTECHNOLOGY OF TRICHODERMA-BASED FEED ADDITIVE WITH CELLULOLYTIC PROPERTIES
DescriptionIn the work, we have presented the information of elaboration of a manufacturing process of Mycocel feed additive with the cellulolytic activity for poul-try industry. Manufacturing process includes follow-ing steps: stock culture maintenance and storage of Trichoderma lignorum 81-17, growing fluid culture of microscopic fungus in sucrose yeast extract me-dium, feed additive with cellulolytic properties out-put and quality control, packaging, storage and disposal of waste. We have shown that the Mycocel is non-toxic feed additive for protozoa and warm-blooded animals (laboratory mice and quails). This study demonstrated total population livability in the experimental group with feed additive. Quail body-weight of experimental group was higher by 6% as compared to the control and feed consumption per 1 kg of live weight of bird was 3,58 kg, 7,5% lower than the control

DISPERSITY OF WASTES AND THEIR PROPERTIES
DescriptionDispersity of wastes of all productions including domestic, agricultural, industrial and violations of the natural systems which are heterogeneous and dispersed formations comprising two or more phases with the developed surface is discussed. Disperse systems of wastes are classified into true solutions, systems of finely dispersed of colloids, coarsely dispersed (mainly mineral wastes) and highly dispersed (organic waste)

INTERRELATIONS BETWEEN PRODUCTIVITY AND ELEMENTS OF ITS STRUCTURE AT GRADES OF SOFT WINTER WHEAT
DescriptionCorrelation interrelations of some morpho¬logical signs of winter wheat and their influ¬ence on productivity are established. Positive correlation communication of efficiency with weight of grain with an ear (r=0,70) is revealed
