Effects of air pollution on production of essential oil in Feijoa Sellowiana Berg. grown in the "Italian triangle of death"
2010
The composition of the essential oils of fruits from Feijoa sellowiana grown in the district of Acerra is compared with those collected from unpolluted sites. Essential oils from the fruits of F. sellowiana were analysed by GC/MS. Sixty compounds, representing 96.6% and 97.8% (unpolluted site and Acerra site, respectively) of the oils, were identified. The major constituents were β-caryophyllene (12.4% and 16.8%), ledene (9.6% and 11.1%), α-humulene (6.3% and 8.2%), β-elemene (4.9% and 5.3%) and δ-cadinene (4.7% and 5.2%) in the control site and Acerra site, respectively. The antioxidant components were increased in response to polluted condition. The acetonic extracts of F. sellowiana from…
First report of Phytophthora citrophthora causing fruit brown rot of Feijoa in Italy
2019
Feijoa (Feijoa sellowiana) is native to South America. In the early 20th Century it was introduced into Sicily (southern Italy), where it is grown as an ornamental plant and for its fruits. In 1985 a Phytophthora brown rot of feijoa fruits was reported in the province of Syracuse (eastern Sicily) (2). Several species of Phytophthora, including P. citricola, P. citrophthora, and P. nicotianae, were recovered from soil samples taken from trees with infected fruits. These species were experimentally inoculated on detached feijoa fruits and all incited symptoms of brown rot. However, only P. citricola was isolated from naturally infected fruits. In early autumn 1999, an outbreak of Phytophthor…
