University of Avignon Prunus persica after aphid infestation


ABSTRACT: The metabolic response of peach tree (Prunus persica) to green aphid (Myzus persicae) has been investigated by GC-MS profiling of the apex polar extracts. Six plants of two cultivars, GF305 (sensitive to M. persicae) and Rubira (resistant), were obtained from the germination of seeds after a 3 months stratification at 4C and grown for eight weeks in a green house before transfer in a growth chamber where the experiment took place. Three plants of each genotype were infested with 10 synchronized green aphid female adults (clones MP06). Aphids were removed after 48 hours and the plant apex (about 100 mg) were collected in liquid nitrogen and thoroughly ground with a ball mill.
