Other claims from this paper (7)
- Intervention effect Exposed xylem wounds produced pigment around the wound in aspen.
- Observation Browning began within 7 days of wounding and spread vertically.
- Mechanism Early pigments were probably phenolic compounds produced in xylem parenchyma from stored lipids.
- Mechanism Early pigment production involved stepwise degeneration of nucleus and cytoplasm.
- Intervention effect Antimicrobial agents increased pigmentation rate at fresh wounds.
- Intervention effect Phloem girdling had no effect on pigment formation.
- Intervention effect Xylem killed without atmospheric exposure did not discolor.
