Effects of modifications forms of growth regulator to development of Ecosil of gerbera (Gerbera hybrida) when seed and vegetative propagation

Russian. Впервые экспериментально доказана высокая биологическая эффективность трех форм регулятора роста (Экосил плюс, ВЭ, Экогум, ВЭ, Экогум АФ, ВЭ) при действии на растения герберы. Применение трех форм препарата в виде 3-кратного опрыскивания оказало положительное влияние на рост и развитие герберы при семенном и вегетативном размножении. Высокая биологическая эффективность действия исследованных форм регулятора роста отечественного производства Экосил (Экосил плюс, ВЭ, Экогум, ВЭ, Экогум АФ, ВЭ) позволяет рекомендовать его для применения при всех видах репродукции на цветочной культуре закрытого грунта - гербере - в условиях Беларуси.

English. Cultivation of different varieties of ornamental plants requires effective application of plant growth regulators, promoting flowering stage, improving ornamentality and resistance of plants. The article presents the results of the analysis of influence of modified forms of plant growth regulator Ecosil on growth and development of gerbera (Gerbera hybrida) while seed and vegetative propagation. Plant growth regulator Ecosil represents ecologically safety substance based on the complex of triterpenic acid extracted out of Siberian fir. The main goal of the research appears investigation of the biological efficiency of three forms of Ecosil (Ecosil plus + VE, Ekogum + VE, Ecogum + AF + VE) on the gerbera plants. Dynamics of the changes of morphological characteristics of gerbera seeds under the influence of the three forms of Ecosil has been analyzed. The changes of morphological indexes of gerbera My Mara seedlings under the influence of Ecosil has been evaluated. The following conclusion has been made: the high bioactivity efficiency of three forms of growth regulator: Ecosil plus + VE, Ekogum + VE, Ecogum + AF + VE have been experimentally proven under on gerbera plants. It allows recommending the use of Ecosil growth regulator on all flower cultivars in the conditions of the Republic of Belarus.
