ABSTRACT

Biggs, A. R. And N. W. Miles. 1985. Suberin deposition as a measure of wound response in peach bark. HortScience 20:902-905.

Seven peach clones were assessed for wound response using suberin deposition, lignification, and lignification + suberization as criteria. Suberin and lignin were measured fluorometrically using a new technique that permits unimpeded observation of suberin autofluorescence. Suberin deposition was first observed in cells of the impervious tissue which forms prior to phellogen generation at the wound. Suberin deposition measured as early as 7 days postwounding was negatively correlated with peach canker incidence.
