“…Greater initial growth for other types of container-grown seedlings was observed previously [1,9]. In the present experiment, the large containerized seedlings had higher initial nutritional status than the large bare-root stock (foliar-N concentrations of 1.64% and 1.48% for the former and the latter, respectively), as a result of their nursery cultivation regime (M. Tourigny, pers.…”

“…Planting bare-root or containerized spruce stock types could play a significant role in the success of plantation establishment [33]. These stock types generally differ in their water relations during the first few years after planting; bare-root seedlings generally experience greater planting stress than containerized seedlings [1,40]. This greater stress is attributed to the reduced root system permeability of bare-root stock, compared to containerized stock [15] and desiccation or injury to roots during planting activities [27].…”

Performance and physiology of large containerized and bare-root spruce seedlings in relation to scarification and competition in Qu�bec (Canada)

-In Québec (Canada), the use of large planting stock is being applied in combination with scarification, since herbicide use is forbidden in public forest. Large containerized and bare-root stock of black spruce were planted on two sites located within the sub-boreal mixedwood region of eastern Québec. We analyzed data to detect main effects and interactions among scarification, competing vegetation and stock type on seedling growth and physiology during the first three growing seasons. Scarification did not improve seedling water relations, third-year height and ground-level diameter, and foliar nutrient concentration. After three years, the two stock types showed similar water relations and nutritional status but the large containerized seedlings performed slightly better than the large bare-root stock in terms of diameter and height growth. Competing vegetation greatly reduced seedling diameter, foliar-N concentration, compared to competition-free seedlings. We discuss results in relation with treatment effects on above-and belowground resource availability to newly planted conifers.

“…According to these authors, peat pellet produced seedlings, showed no qualitative advantage over bare-root seedlings even after several years of growth in the nursery. Alm (1983) obtained the opposite results, observing greater stress in plants grown in the ground nursery. Transplant shock was manifested by a reduction of the root system and a greater degree of damage than observed in container-grown plants.…”

The effectiveness of different peat-based substrates was compared for the propagation of two mountain tree species (silver fir and European beech). The experiment was set up in the spring of 2006, and seedlings were grown in polystyrene multipots for 2 years. Four types of substrate were applied: (1) a newly prepared 1:1 peat-sawdust mixture; (2) a peat-sawdust mixture which had already been used for five production periods; (3) a peat substrate produced in the ‘Nędza’ container nursery (Rudy Raciborskie Forest District), consisting of peat and perlite; (4) a peat substrate, as described for (3), with added mycorrhizal fungus Hebeloma crustuliniforme. After sowing, polystyrene multi-pots were placed in a transparent tent. During the autumns of 2006 and 2007, for both species and each substrate type, 25 seedlings were randomly selected for measurement of their above-ground height, root length, root collar diameter, above- and below-ground fresh weight. Growth of one-year old and two-year-old seedlings of both species differed depending on their substrate. The application of a mycorrhizal inoculum positively affected seedling establishment, since the best height growth and largest seedlings of both species were grown on substrate (4). The growth of one-year-old fir seedlings in the ‘old’ peat and sawdust mixture (2) was similar to those seedlings grown on the turf substrate (3). Root:shoot allocation differed among the substrates. In fir, root:shoot allocation was approximately equivalent at 1:0.9, whereas for beech it was 1:2 in one-year old seedlings and 1:1.5 in two-year old seedlings.

“…Moreover, large seedlings can be produced either in containers or as bareroot stock. Field comparisons of containerized and bareroot seedlings are numerous (e.g., [19][20][21][22]). However, most studies have examined stock types of different initial dimensions (see [23]); few have investigated the relative performance of bareroot and containerized seedlings that are similar in size at the time of planting [24][25][26].…”

We established four experimental plantations to evaluate the main and interaction effects of timing (year of application) of mechanical release and stock type (containerized or bareroot) on the establishment success of large Picea glauca seedlings eight years after outplanting on high-competition sites in Quebec (Canada). We also monitored percent cover and height of target vegetation groups as well as the amount of photosynthetically active radiation available to crop trees. Our results indicate that the use of large containerized or bareroot stock had limited effects on seedling growth, although bareroot seedlings presented higher mortality than containerized seedlings. Mechanical release enhanced seedling growth, compared to the control. Delaying treatment by two years impacted crop tree dimensions, although differences were minimal. Survival was not affected. We conclude that large containerized seedlings should be favoured over bareroot stock for reforestation on high-competition sites and that the release guidelines developed for standard size seedlings are applicable to the large dimension P. glauca stock tested in this study.
