KEY MESSAGE : Migration ability of the PWN through wood branch tissues of adult Maritime pine trees significantly differed among Iberian provenances and this variation was related to differences in anatomical and chemical defensive traits. The pinewood nematode or pine wilt nematode (PWN; Bursaphele...
