Abstract


Silvicultural production of high quality planting material is supposed to be of primary importance in the provision of artificial forestry. The search for modern intensive technologies of cultivation continues, and hence study of the effect of micobiota seeds of different colour on the quality of planting material is still relevant today. Study of sustainable forms of pine and perspective in colour seeds, especially their growth and development to improve productivity and biological stability of forest plantations is one of the most important tasks of modern forestation. Epiphytic and endophytic microbiota composition of Scots pine seeds of different colours like black, brown, and white in different culture conditions (meat- peptonic agar (MPA), Capek medium, potato agar (KGA), a moist chamber) and the results of research colonization of microorganisms on seeds of different colour and harvested in forest stands of different age groups, are studied. Black seeds as seed form are promising because they are the most prevalent in each age group and the least populated with harmful microorganisms (from 47 to 75 0 %, 3 %) compared to brown seeds forms (75. 3 % black to 97 % on brown seeds). Maximum micobiota colonization under all conditions of cultivation was found in ripe seed planting from 40 % to 88.7 %, the minimum was observed in seeds of young age planting (73. 3 % to 74. 0 %).
