Regeneration of Injured Root Systems in Noble Fir

Hugh Wilcox Botanical Gazette 1955. doi:10.1086/335865

Other claims from this paper (14)

Observation Most active root repair occurs June to September, with nearly all pruned roots producing laterals within 20-30 days.
Observation Some seedlings regenerate roots in February and March.
Intervention effect Root pruning does not form a compact fibrous root system.
Intervention effect Severed roots form replacement roots near pruned surfaces rather than more laterals along root lengths.
Observation Regenerated roots elongate rapidly.
Association Distal regenerated roots are as likely to be lost in transplanting as unpruned long laterals.
Observation Roots pruned at age 1-3 years generally regenerate a number equal to their xylem poles.
Observation Older roots can regenerate more roots at the wound than their parent xylem pole count.
Observation Pruned noble fir roots show similar basipetal wound-healing zones.
Observation Lateral root primordia originate near the pruned surface below wound cork.
Observation In roots under 2 or 3 years old, primordia generally arise from cambium outside protoxylem points.
Observation After secondary growth, the pericycle contributes little to lateral root production.
Observation Vascular maturation is accelerated in regenerated compared with normal lateral roots.
Observation Regenerated-root xylem connects to recent secondary xylem of the mother root.
