Mark record


Complements of needle primordia were assessed on terminal buds of 1-year spruce (Picea) seedlings formed during experimental treatments of temperature, light intensity, soil moisture potential, and nutrient supply. Several provenances of widely scattered locations were examined in each experiment. While there were strong provenance and treatment effects in most experiments, in no instance was provenance × treatment interaction detected. The results are discussed in relation to genotype × environment interactions reported in field trials.
