A scientific breakthrough that seeds are not responsible for spreading citrus variated chlorosis (CVC) could make it easier for Brazil and northeastern Argentina (NOA) to export their fruit.

Obispo Colombres Agro-industrial Experimental Station (EEAOC) technical director Dr Daniel Ploper, told www.freshfruitportal.com the station's team studied six varieties of lemons planted in places with high incidence of CVC in Brazil, in conjunction with the Paraná Agronomy Institute

The  employed four different orange cultivars as positive control plants planted in a commercial block where there was evidence of the disease.

The scientists analyzed the seeds and germinated seedlings of up to 12 months in age, using polymerase chain reaction (PCR) and found the bacteria was not present. They are still testing younger seedlings of just a few weeks of age.

Dr Ploper refused to be drawn on the effects of his research, however, it's clear there could be phytosanitary export implications.

The results of his study are due to be presented at the Brazilian Plant Pathology Congress next month, with plans to publish the results in a peer-reviewed scientific journal by the end of the year.
