Mark record


A technique for marking tree seeds to facilitate their identification or recovery in nursery and field experiments is described; the method consists of coating the seeds with latex and day-fluorescent pigments. The coating, tested on black spruce (Piceamariana [Mill.] B.S.P.) seed, made possible +95% recovery of seed buried 1–6 cm deep in natural seedbeds for 22 months. Germination from freshly coated seed was significantly slower and lower than from untreated seeds, but after 4, 10, 16, and 22 months storage, germination from coated seed was the same as from untreated seed, i.e., +98%.
