Abstract

Detection of apple proliferation and pear decline in southern Italy.

Abstract

Apple trees showing proliferation symptoms and pear trees showing pear decline symptoms were sampled in southern Italy during 1994-95 and examined by PCR amplification and restriction site analysis of the PCR products. Phytoplasmas responsible for causing apple proliferation and pear decline were detected in all samples from symptomatic apple trees and in most samples from diseased pears, respectively. This is the first report of the occurrence of these phytoplasmas in southern Italy.
