Qualidade Sanitária E Fisiológica De Sementes De Chia

Abstract

RESUMOCom o objetivo de avaliar a incidência fúngica e a qualidade fisiológica de sementes chia (Salvia hispanica L.), foram analisados seis lotes de sementes da espécie, provenientes do mercado local do município de Pelotas-RS, Brasil. Para a análise sanitária o método utilizado foi o "Blotter Test" e para o teste da qualidade fisiológica o teste de germinação e índice de velocidade de emergência (IVG). Os resultados obtidos permitiram constatar que os Lotes 3 e 5 não apresentaram incidência de fungos e nos demais evidenciou-se a presença de Aspergillus sp., Cladosporium sp., Bipolaris sp., e Fusarium sp. Sementes de chia disponíveis no comércio do município de Pelotas-RS apresentam baixa incidência de fungos fitopatogênicos, porém há variação na qualidade fisiológica. PALAVRAS CHAVE: fungos, germinação, Salvia hispanica L. HEALTH AND PHYSIOLOGICAL QUALITY OF SEEDS OF CHIA ABSTRACTIn order to assess the fungal incidence and physiological quality of chia seeds (Salvia hispanica L.) were analyzed six seed lots of the species, from the local market in the municipality of Pelotas, Brazil. For health analysis method used was the "Blotter Test" and for testing the physiological quality germination test and emergence speed index. The results revealed that Lots 3 and 5 showed no incidence of fungi and the other showed the presence of Aspergillus sp., Cladosporium sp., Bipolaris sp. and Fusarium sp. Chia seeds available in the trade of the municipality of Pelotas-RS present low incidence of phytopathogenic fungi, however there are variation in physiological quality.

Sanity, Pathogenicity, and Transmission of Fungi associated with Seeds of chia coming from the Southern Region of Tocantins

“…The results of fungal incidence are presented as percentages in Table1. [6] when evaluating samples of commercial Chia seeds, verified the presence of fungi: Fusarium sp., Cladosporium sp., Bipolaris sp., and Aspergillus sp. Jiménez et al, (2015) [18] when studying the same species Salvia hispânica L. also determined the presence of contaminating filamentous fungi in seven commercial samples of seeds evaluated observing the presence of the following fungi genera: Aspergillus sp., Aspergillus niger., Aspergillus flavus, Penicillium sp., Cladosporium and Curvularia sp.…”

“…However, the consumption of this seed has aroused a growing interest in Brazil, mainly in the regions of the West Paranaense and northwest of Rio Grande do Sul began to gamble and to plant the culture of Chia in the last harvests, intending to present good Results [3][4][5]. The propagation of Chia culture is especially due to seeds, so the sanitary quality is a factor of great relevance, for better viability, germination, vigor, and production of Chia seeds [6]. Also, considering that better sanitary quality can reduce the incidence of diseases in culture.…”
