The wax structure of the developing needles of Pinus sylvestris progenies infected by Lophodermella sulcigena.

Abstract

The development of the stomatal area wax structure of Scots pine ( L.) needles was studied in flushing needles with a scanning electron microscope. The needles were obtained from eleven Finnish plus tree progenies. The needles were taken from trees that were either nearly uninfected or heavily infected by (Rostr.) Höhn.Pinus sylvestrisLophodermella sulcigena
