OBTAINING PLANT GROWTH REGULATORS BASED ON CONIFEROUS EXTRACTS OF ABIES SIBIRICA AND STUDYING THEIR FUNGICIDAL PROPERTIES TO IMPROVE THE SOWING QUALITIES OF WHEAT SEEDS

OBTAINING PLANT GROWTH REGULATORS BASED ON CONIFEROUS EXTRACTS OF ABIES SIBIRICA AND STUDYING THEIR FUNGICIDAL PROPERTIES TO IMPROVE THE SOWING QUALITIES OF WHEAT SEEDS

Abstract

Siberian fir (Abies sibirica Ledeb.) is one of the main forest-forming species of Siberia. At the same time, wood greens (WG) of fir, being a rich source of valuable biologically active substances, is a waste product of the woodworking industry. The article presents the results of obtaining samples of coniferous extracts isolated from fir wood greens for use in agriculture. The obtained coniferous extracts contain such extractive components as complex of triterpenic acis (TAs) and a number of other associated biologically active substances. The composition of the obtained samples was analyzed by HPLC-MS, according to the procedure that was developed for sample preparation and analysis of coniferous extracts samples. The content of TAs in the samples reaches 67%. The fungicidal and growth-regulating properties of the obtained samples were studied on the seeds of soft spring wheat (Triticum aestivum L.) varieties “Ikar” and “KVS Buran”. The results of the effect of five samples on laboratory germination and on microorganisms causing fusarium and penicillosis present on wheat seeds are shown. It was found that from two fungal diseases, fusariosis was better suppressed with the application of the obtained samples. Statistically significant reduction in seed infestation was found with the treatment of samples 1 and 5, the infestation decreased by 20 and 24% respectively. Laboratory germination increased in the experimental variant under the influence of sample 1 statistically significantly compared to the control by 20%.

Пихта сибирская (Abies sibirica Ledeb.) является одним из основных лесообразующих видов Сибири. При этом древесная зелень (ДЗ) пихты, богатый источник ценных биологически активных веществ, является отходом деревообрабатывающей промышленности. В статье представлены результаты получения образцов хвойных экстрактов из ДЗ пихты для применения в сельском хозяйстве. Полученные хвойные экстракты содержат в составе такие компоненты, как комплекс тритерпеновых кислот (ТТК) и ряд других сопутствующих биологически активных веществ. Анализ состава полученных образцов проводили с помощью метода ВЭЖХ-МС по методике, которая была разработана для пробоподготовки и анализа образцов хвойных экстрактов. Содержание тритерпеновых кислот в образцах достигает 67%. Были изучены фунгицидные и росторегулирующие свойства полученных образцов на семенах мягкой яровой пшеницы (Triticum aestivum L.) сортов «Икар» и «КВС Буран». Показаны результаты влияния пяти образцов на лабораторную всхожесть и на микроорганизмы, присутствующие на семенах пшеницы, вызывающие фузариоз и пенициллез пшеницы. Обнаружено, что из двух грибных заболеваний при применении полученных образцов лучше подавляется фузариоз. Установлено статистически значимое уменьшение зараженности семян при обработке образцами 1 и 5, инфицированность понизилась на 20 и 24% соответственно. Лабораторная всхожесть увеличилась в опытном варианте при воздействии образцом 1 статистически достоверно на 20% по сравнению с контролем.
