Epin-extra, altura da planta, diâmetro das inflorescências, número de inflorescências, ZirconResumo
Os reguladores de crescimento tiveram efeito significativo nos parâmetros morfométricos da zínia graciosa, dentre os quais o mais eficaz foi o Epin-extra. Sendo tratadas duas vezes com epibrassinolídeo, as plantas de zínia apresentaram uma gama de cores mais saturada. O Zircon (um produto do grupo dos ácidos hidroxicinâmicos) teve um efeito menor nos parâmetros morfométricos do que o Epin-extra. O Mechta (em tradução inglesa como Dream), que ao longo do texto este nome será usado para esta variedade, foi a mais resistente a condições climáticas desfavoráveis, quando comparado com o Oranzhevyy korol’ (em tradução inglesa como Orange King), que mais adiante no texto esse nome será usado para a variedade que tolerou facilmente ao frio recorrente e as secas durante o período de crescimento. Além disso, a variedade Dream revelou-se mais uniforme em altura e na formação de rebentos de floração lateral, o que é importante para criar composições de flores ornamentais. O uso de reguladores de crescimento e fertilizantes minerais aumentou a percepção visual da zínia. Entre as variedades, a variedade Dream apresentou as qualidades decorativas mais preferidas.
