Abstract(s)
Os ataques de traça-verde foram monitorizados em três cultivares de oliveira, ‘Arbequina’, ‘Cobrançosa’ e ‘Galega Vulgar’,numolival de cincoanos de idade e na ‘Galega Vulgar’ também numaparcela com um ano de idade, na zona de Belmonte. As observações decorreram de 5 de Abril a 7 de Novembro de 2010, tendo sido observados os primeiros sintomas em 7 de Julho. ‘Cobrançosa’ foi significativamente menos atacada ao longo de todo o períodode observações, não tendo sido detectadas diferenças significativas entre as restantes. Com o objectivo de procurar explicar o maior ataque à ‘Cobrançosa’, compararam-se as espessuras de folhas das diferentes cultivares em corte histológico, não se tendo verificado diferenças significativas. A nível histológico também não se observaram diferenças relativamente à presença e abundância de tricomas.
Abstract: The attacks of jasmine moth were monitored in three olive cultivars, ‘Arbequina’, ‘Cobrançosa’ and ‘Galega Vulgar’,in a five years old olive grove and also in a plot of‘Galega Vulgar’ one year old near Belmonte. The observations were carried out in 2000, from April 5 to November 7 and the first symptoms were observed on July 7. ‘Cobrançosa’ was significantly less attacked throughout the observation period and no significant differences were detected between the remaining. In order to explain thesedifferences, leaf thickness of the different cultivars were compared by histological cuts but no differences were detected. No other differences regarding the presence and abundance of trichomes were found.
