Summary: | Abstract Alstroemeria faces a stressful condition during its postharvest phase, as the leaves tend to yellow before the senescence of the flowers. Therefore, this study aimed to evaluate and compare the efficacy of different solutions previously recommended for the postharvest conservation of Alstroemeria hybrida L. cv. Akemi. The preservatives solutions tested included Florissant 210® with chlorine, 1-methylcyclopropene, benzyladenine, cycloheximide, silver thiosulfate, salicylic acid, spermine, silver nanoparticles, calcium chloride, gibberellin, Florissant 210®, Crystal, along with two control treatments using tap water and artesian well water. The results indicated significant differences when comparing the different water sources used in preparing the solutions. An increase in microbial population was observed over time postharvest, with genera Pseudomonas spp. and Bacillus identified. When tap water was utilized, the most suitable solutions included the addition of benzyladenine, gibberellin, Florissant 210®, Crystal, and Florissant 210® with chlorine. These results inform producers about selecting preservatives and water sources to enhance postharvest longevity and quality.
Resumo Alstroemeria apresenta um desafio durante sua fase pós-colheita, pois as folhas tendem a amarelar antes da senescência das flores. Portanto, este estudo teve como objetivo avaliar e comparar a eficácia de diferentes soluções previamente recomendadas para a conservação pós-colheita de Alstroemeria hybrida L. cv. Akemi. Os conservantes testados incluíram Florissant 210® com cloro, 1-metilciclopropeno, benziladenina, cicloheximida, tiossulfato de prata, ácido salicílico, espermina, nanopartículas de prata, cloreto de cálcio, giberelina, Florissant 210® e Crystal, juntamente com dois tratamentos de controle usando água da torneira e água de poço artesiano. Os resultados indicaram diferenças significativas ao comparar as diferentes fontes de água utilizadas na preparação das soluções. Foi observado um aumento na população microbiana ao longo do tempo pós-colheita, com os gêneros Pseudomonas spp. e Bacillus identificados. Quando uma estação de tratamento de água foi utilizada, as soluções mais adequadas incluíam a adição de benziladenina, giberelina, Florissant 210®, Crystal e Florissant 210® com cloro. Esses resultados informam os produtores sobre a seleção de conservantes e fontes de água para melhorar a longevidade e qualidade pós-colheita. |
