Efecto del tratamiento térmico sobre la presencia de virus en bulbos de ajo (Allium sativum L.)
It was evaluated the virus presence in cloves of 24 varieties of garlic before and after being thermo-treated using the serological technique DAS-ELISA for TEV, SLV, GarCLV, OYDV, and LYSV. Garlic bulbs were exposed to 33 ± 1 °C during a period of six weeks. After thermic treatment, 23 varieties...

| Sumario: | It was evaluated the virus presence in cloves of 24 varieties of garlic before and after
being thermo-treated using the serological technique DAS-ELISA for TEV, SLV, GarCLV,
OYDV, and LYSV. Garlic bulbs were exposed to 33 ± 1 °C during a period of six weeks. After
thermic treatment, 23 varieties had one virus at least; however, none of the five viruses was
detected in the cloves of the variety Español, also, the variety ChJO 13 was only positive to
TEV. TEV was the more persistent virus through the thermic treatment. In spite of virus
or variety, the percentage of virus-positive cloves was 53.5 and 45.1% before and after
thermic treatment respectively. Most of the cloves showed multiple infections in diverse
combinations. Only TEV and SLV appeared as single infections or with only one virus; after
thermic treatment only TEV kept this characteristic. Viral concentration for TEV did not
show significant changes before and after thermic treatment. |
