Germination of stratified seed was highest for immature fruit of red elder (Sambucus pubens Michx.), harvested in early August, and for fruit of Tatarian honeysuckle (Lonicera tatarica L.), harvested in mid-August. Neither specific gravity nor moisture content of the fruit were related to seed germination.
Intensity of needle coloration for inbred seedlings of Picea pungens Engelm. (blue spruce) increased with seedling age. Needle color ratings for 7- and 10-year-old, inbred seedlings and parental trees were correlated. Mean heights of the 10-year-old, inbred progenies ranged from 50 to 76 cm, but bore no relationship to parental selffertility or needle color. In one selection, 94% of the inbred seedlings had silvery-blue foliage.
