Growing environment and container type influence field performance of black spruce container stock

Black spruce (Picea mariana [Mill.] B.S.P.) overwintered container crops produced in four container types spanning a range of container sizes and seedling rearing densities were compared for two consecutive years. In 1989 two growing environments (greenhouse and outdoors) were compared. In 1990 three growing environments (greenhouse, coldframe, and outdoors) and two hardening regimes (short day and natural) were compared. Seedlings were outplanted during the spring of 1989 and 1990 and total height and survival were assessed for five years.The outdoor-grown crop was shorter, smaller in root collar diameter and had less dry weight at time of planting than the crops produced in the greenhouse (1989 study) and in the greenhouse and coldframe (1990 study). Although the greenhouse crops in both studies were larger at time of planting, the outdoor-grown crops (1989 and 1990) and coldframe-grown crop (1990) displayed significantly greater annual height increment in the first two years after planting. The enhanced early height growth of the outdoor-grown crops may be due to the natural acclimation created by their growing environment.Seedlings grown in a large volume container, at a low plant density (441 plants/m²), had significantly larger root collar diameters and total dry weights at time of planting than seedlings grown in a smaller volume container at a high plant density. Stem volume production in the field was greater on seedlings from larger volume containers grown at low densities.

Resistance and tolerance in juvenile interior Douglas‐fir trees Pseudotsuga menziesii var. glauca artificially inoculated with Armillaria ostoyae

Plants utilize two general strategies to cope with pathogen attack. They either limit or resist the pathogen (termed ‘resistance’) or they cope with the disease by surviving and growing (termed ‘tolerance’). Both strategies tend to increase plant fitness; however, there are possible costs, trade‐offs and interactions associated with each strategy. This study focused on five half‐sib interior Douglas‐fir families [Pseudotsuga menziesii var. glauca (Beissn.) Franco] that were putatively classified as either resistant or susceptible to Armillaria ostoyae in a previous greenhouse study of seedling families challenged with A. ostoyae. We compared their survival rates in the greenhouse study with results of juvenile trees from the same five families that were artificially inoculated in field conditions. Both resistance and tolerance appeared to be operating in the field test trees, and a possible trade‐off between resistance and tolerance was detected. Significant differences were detected among the five families for stem radial growth following infection at the tree root collar. Compared with the putatively susceptible families, resistant families had smaller lesions and lower proportional root collar girdling. Tolerant families generally had larger lesions but demonstrated better growth when diseased than resistant families. One tolerant family that was a good survivor in the greenhouse survival study presented vertically shaped lesions that were large in area but had greatly reduced proportional root collar girdling. While a second family showed tolerant traits in the field study, its poor survival in the greenhouse study agreed with the large horizontally spreading lesions associated with high root collar girdling in the field study trees. Survival rankings of the five families in the greenhouse study mostly agreed with results from the field study based on the proportion of collar girdling among families. These host responses are discussed with respect to stability, quantity and quality of stands and products.
