| Popis: | The use of several solutions as floral preservatives in extending the vase life of cut flowers has been an all-time research objective to meet the demands of florists and buyers. One of the major problems faced with the longevity of cut flowers is the accumulation of microorganism in the vase floral solution. This study was carried out to investigate the influence of Aloe vera gel and Silver thiosulphate solutions used as vase solution on the microbial population of Heliconia cut flowers. The experiment was carried out in the plant physiology laboratory, Floriculture programme, National Horticultural Research Institute, (NIHORT); Ibadan, Nigeria (7O25” N and 3O52” E). Six treatments supplemented with 1% sucrose were used in this experiment, they include; 1%, 2% and 4% Aloe vera gel solutions, 0.5% and 1% Silver thiosulphate solutions and distilled water (which serve as control) labeled AV1, AV2, AV3, STS1, STS2 and CO respectively. All treatments used for the vase life of Heliconia cut flowers were significantly (p ≤ 0.05) different in the parameters analyzed as compared to the control. The vase life, relative fresh weight and relative water content of Heliconia cut flowers were best with Aloe vera gel solutions compared to the control with AV3 recording the longest vase life of 12 days (58.21%). The microbial population in the vases of the cut flowers was greatly reduced with the application of the silver thiosulphate solutions (STS1 and STS2) compared with the control with STS2 recording the lowest microbial colony at 32.67 CFU mL-1. Promoting the use of organic floral preservatives should be encouraged as it is eco-friendly and cost effective. The result of the study reveals that the use of 4% Aloe vera solution has the potential to reduce microbial growth and also enhance the longevity of the cut flowers. Resumo O uso de diversas soluções conservantes na extensão da vida de vaso de flores de corte é um tema de pesquisa importante e visa a atender a demanda mercadológica de floristas e consumidores. Um dos maiores problemas relacionados à longevidade de flores de corte é o acúmulo de microraganismos na solução de vaso. Este estudo foi conduzido para investigar a influência do gel de Aloe vera e do tiossulfato de prata como aditivos de solução conservante para o controle da população microbial em Heliconia de corte. O experimento foi conduzido no Laboratório de Fisiologia, programa de floricultura, National Horticultural Research Institute, (NIHORT); Ibadan, Nigeria (7O25” N e 3O52” E). Foram delineados seis tratamentos contendo 1% sucrose além de 1%, 2% and 4% Aloe vera gel ou 0,5% e 1% de tiossulfato de prata ou água destilada (tratamento controle), denotados por AV1, AV2, AV3, STS1, STS2 and CO respectivamente. Todos os tratamentos empregados para o aumento da vida de vaso de Heliconia de corte foram estatisticamente (p ≤ 0,05) diferentes nos parâmetros analisados quando comparados com o tratamento CO. A vida de vaso, peso fresco relative, e conteúdo relative de água de Heliconia de corte tiveram melhor desempenho com as soluções contendo gel de Aloe vera quando comparadas com o controle, enquanto o tratamento AV3 registrando a maior vida de vaso com 12 days (58,21%). A população microbial nos vasos das flores de cored foram drasticamente reduzidas com a aplicação de tiossulfato de prata (STS1 and STS2) na solução conservante quando comparado com o controle, e o tratamento STS2 registrou a menor contagem de colônias com 32,67 CFU mL-1. A promoção de preservativos florais orgânicos deveria ser ampliadas pois mostrou-se efetiva com uso de gel de Aloe vera, além de ser ambientalmente amigável e apresentar bom custo-benefício. O resultado deste estudo revelou que o uso de gel de Aloe vera a 4% tem o potencial de reduzir o crescimento microbiano e aumentar a longevidade de flores de corte. |
