Abstract

Differences in early root production (number, length, and dry weight) after 17 d paralleled subsequent differences in accumulation of aboveground biomass that were observed when 2 Populus balsamifera × deltoides (Jackii 4 and Jackii 7) and 3 Populus deltoides × nigra (DN 2, DN 22, and DN 15) hybrids were compared. Total root length and dry weight of Jackii 4 was 4 times that of Jackii 7. Both DN 2 and DN 22 had a total root length twice that of DN 15. Hybrids differing in biomass production displayed different patterns of carbohydrate utilization. Initial myoinositol concentration in cuttings may be used in early selection for rooting performance. -from Authors
