Creator:

Beckman, Kent Mardsen

Abstract:

Longevity and germination of seed of western dwarfmistletoe (Arceuthobium campylopodum Engelm. f. campylopodum) of ponderosa pine (Pinus ponderosa Laws.) was investigated to determine: 1) the influence of humidity and temperature on seed viability and deterioration during storage; 2) the physiology of seed dormancy; 3) the composition of seed reserve food...
