Testes de vigor para avaliação de sementes de pepino

Abstract: Dentro de um programa de controle de qualidade, a avaliação do vigor de sementes é fundamental e necessária para o sucesso da produção. O trabalho teve por objetivo comparar diferentes métodos para avaliação do potencial fisiológico de sementes de pepino. Para tanto, cinco lotes de sementes do híbrido Safira foram submetidos aos seguintes testes: germinação, primeira contagem de germinação, condutividade elétrica (4x50 sementes; 25ºC; 50 e 75mL; 12, 18 e 24h), germinação a baixa temperatura (4x50 sementes; 18º… Show more

“…Among tests used to assess cucumber seed vigor, literature includes the germination first count (torres et al, 1999), traditional accelerated aging and saturated salt accelerated aging (Bhering et al, 2000;Abdo et al, 2005;Lima and Marcos-Filho, 2009), electrical conductivity (Abdo et al, 2005), controlled deterioration (Pandey et al, 1990;Alsadon et al, 1995), percentage or speed of seedling emergence (Barbedo et al, 1997;Lima and Marcos-Filho, 2009), and seedling length ).…”

“…The efficacy of the procedure using a saturated NaCl solution for evaluation of vegetable seed vigor has been emphasized by several authors, including Rodo et al (2000) in carrot seeds, Torres and Marcos-Filho (2003) in melon, Abdo et al (2005) in cucumber, Bhéring et al (2006) in hot pepper, Dutra and Vieira (2006) in squash, Hyatt and TeKrony (2008) in onion, and Kikuti and Marcos-Filho (2012) in lettuce. The SSAA has advantages in regard to simplicity, similarity in regard to levels of deterioration (closer water contents) observed during seed storage on a commercial scale, and lower additional effect of microorganisms, minimizing the effects of pathogens on the results of the test (Jianhua and McDonald, 1996;Marcos-Filho, 2015).…”

“…Among the tests used for assessing the vigor of Cucurbitacea seeds, accelerated aging with the use of saturated salt solution (Abdo et al, 2005) and the cold test (Casaroli et al, 2006 a,b) are important options. The accelerated aging test is among those most recommended for use in seed quality control programs , and it stands out through its efficacy in identifying important differences in the physiological potential of seed lots and its association with seed performance over the storage period.…”

“…Para a família das cucurbitáceas, os melhores resultados obtidos na separação de lotes de sementes por níveis de vigor foram obtidos para os testes de envelhecimento acelerado para melancia (BHERING et al, 2003), para mogango (MALONE at al., 2008), para pepino (ABDO et al, 2005) e para melão (BHERING et al, 2004;MUNIZ et al, 2004). Cabe ressaltar que as metodologias utilizadas nesses trabalhos foram totalmente distintas das utilizadas no presente estudo.…”
