Abstract
Monthly changes in amino acids, carbohydrates, glutathione and minerals in needles and roots, and the growth of transplanted and non-transplanted blac k spruce [Picea mariana (Mill) B.S.P.] seedlings during one growing season were compared. Seedlings were watered throughout the growing season. Shoot water potential did not differ significantly between control and transplant ed seedlings. However, growth reduction in transplanted seedlings suggests that other transplant-induced effects reduced growth. Compared with control seedlings, needles of transplanted seedlings showed significantly lon er l evels of all macronutrients and some micronutrients. certain individual and total amino acids and sucrose. Needles of transplanted seedlings showed hi gher concentrations of tryptophan and certain carbohydrates. Transplanted s eedling roots had relatively minor differences in nutrient and biochemical constituents compared with control seedling roots. The total amino acid con tent of the needles appeared to have potential for use as a biochemical ind icator of transplant shock in non-water-stressed black spruce seedlings.
