“…Therefore, according to measures of morphology on end-ofnursery seedlings, those taller but slender stocks had higher SQ ratio. Although the high SQ is fairly accepted as positive predictor for seedling quality of hard wood species (Tsakaldimi et al, 2013), opposite queries on the positive relationship between SQ and seedling quality have never stopped (Bayala et al, 2009). Therefore, according to the calculation for SQ, quality of Japanese maples seedlings in our study tended to be declined by the extended photoperiod.…”

Leachate nutrients from the nursery of containerized tree seedlings result in risks of inefficient fertilization through nutrient loss and contamination of ground water. In the present study, seedlings of Buddhist pine (Podocarpus macrophyllus) and Japanese maple (Acer palmatum) were cultured in containers of three differing sizes under contrasting photoperiods of naturally 11 h per day and an extended one of 20 h per day. Controlled release fertilizer (CRF, 14-14-14) was used to feed seedlings with sufficient nutrients for 5 months from June to November 2014. At the end of experiment, seedlings from all types of containers were measured for height and root collar diameter, whilst leachates were collected to determine nutrient concentrations of available phosphorus (P), potassium (K), ammonium and nitrate nitrogen (N) therein. Growth of both seedling species increased with the volume of container, but only growth of Japanese maple seedlings responded to photoperiod. In spite, there was greater amount of nutrients leached from containers planted with Buddhist pine than with Japanese maple; nearly no nutrient in the leachate affected by photoperiod. A negative correlation was found between concentrations of leachate nutrients and seedling height growth in all container sizes. In conclusion, nutrient leaching is a nonignorable but predictable factor by seedling height growth during the intensive culture of slowly growing seedlings of ornamental trees under the extended photoperiod.

“…The container stock had basal calipers at planting 2.5 to 3 times larger than the bareroot stock of the same age (Tables 1-3). Tsakaldimi et al (2013) found that basal caliper was the variable that most accurately predicted survival of five tree species in Mediterranean restoration plantings. Davis and Jacobs (2005) reported that field performance of oak seedlings was positively correlated with large root volumes, high root fibrosity, and an increase in number of first-order lateral roots (FOLR).The repeatedly air-root-pruned container planting stock was superior in all three morphological measures of planting stock quality compared to the bareroot planting stock.…”

“…Although planting stock quality is difficult to quantify (Haase, 2008), the most reliable morphological indicator of quality and future survival and growth in the field continues to be basal stem diameter because it is highly correlated with many metrics of root system size (Davis & Jacobs, 2005;Dey & Parker, 1997;Tsakaldimi et al, 2013;Wilson & Jacobs, 2006). Recent studies have shown that field performance of bareroot nursery stock can be improved by increasing the amount of organic matter in nursery beds (Davis et al, 2006) or decreasing seedling bed densities to produce larger seedlings (Schultz & Thompson, 1996).…”

Benefits of repeated air-root-pruning of seedlings when stepping up to progressively larger containers include excellent lateral root distribution immediately below the root collar and an exceptionally fibrous root ball. To evaluate long-term field performance of repeatedly air-root-pruned container stock, three plantings of swamp white oak (Quercus bicolor Willd.) 10 to 13 years old were located that also included bareroot planting stock. Initial and final stem diameter and height and above-ground green weights were determined on randomly selected trees at each site. On a site with a sandy, excessively drained, high pH soil, trees (age 10) from container stock were 1.5 times taller, 2.3 times larger in dbh, and 2.8 times greater in green weight than trees from bareroot stock which averaged only 2.9 m tall, 3.9 cm dbh, and 16.3 kg green weight. On a site with high clay, poor internal drainage, and frequent flooding, trees (age 12) from container stock were 1.4 times taller, 1.8 times larger in dbh, and 4.1 times greater in green weight than trees from bareroot stock which averaged 4 m tall, 7.3 cm dbh, and 28 kg green weight. On an upland site with deep loess soils, there was a trend for trees (age 13) from container stock to be only slightly larger than trees from bareroot stock with each stock type averaging 9.6 m tall, 20 cm dbh, and 177 kg green weight. Repeated air-root pruning produced lateral roots immediately below the root collar * Corresponding author.J. W. Van Sambeek et al. 164 that resulted in large container stock with large well-balanced root systems that were competitive on harsh or less than ideal oak sites. Although the process is relatively labor intensive, propagation of repeatedly air-root-pruned container stock is readily adaptable internationally to locally available sources of organic matter and open-bottom containers.

“…Os padrões de altura e diâmetro das mudas de espécies florestais possuem relação direta com as taxas de sobrevivência iniciais das espécies nos primeiros anos do plantio (Grossnickle, 2012;Tsakaldimi et al, 2013). Embora algumas características morfológicas possam perder o seu valor preditivo com o tempo, em função dos fatores ambientais e genéticos atuantes, o desempenho em campo pode ser estimado a partir da análise da qualidade da muda em viveiro, em especial pela variável diâmetro à altura do coleto (Tsakaldimi et al, 2013).…”

RESUMO:A análise do estabelecimento inicial das mudas no campo constitui etapa fundamental para a seleção de espécies arbóreas nativas com maior potencial de se desenvolverem em condições adversas, a exemplo daquelas encontradas em ambientes perturbados. O objetivo deste estudo foi investigar a sobrevivência e os padrões de crescimento de espécies florestais nativas de diferentes grupos ecológicos crescendo em área alterada no Amazonas. O experimento foi instalado em delineamento de blocos casualizados com onze espécies (seis espécies pioneiras -P e cinco espécies não pioneiras -NP), cinco repetições e espaçamento 3 × 2 m. Depois de dez meses do plantio, foram observadas taxas de sobrevivência superiores a 80% para a maioria das espécies nos diferentes grupos ecológicos, à exceção de Sclerolobium paniculatum (40%) e Cedrela odorata (67%). As espécies com maiores valores de incremento em altura e diâmetro foram: Ochroma pyramidale e Trattinnickia rhoifolia (P), Parkia velutina, Hymenaea courbaril, Cedrela odorata e Endlicheria anomala (NP). Os maiores incrementos em área de copa foram observados em Sclerolobium paniculatum, Trattinnickia rhoifolia e Enterolobium schomburgkii (P) e Hymenaea courbaril (NP). As espécies florestais estudadas possuem alta taxa de sobrevivência, porém apresentam padrões distintos de crescimento, os quais deverão ser considerados na definição das espécies a serem utilizadas em futuros programas de reflorestamento de áreas alteradas no Amazonas. Estabelecimento inicial de espécies florestais em plantio para a recuperação de área alterada no Amazonas ABSTRACT: The analysis of initial seedling establishment in the field constitutes a fundamental step for the selection of native tree species with greater potential to develop under adverse conditions, like those found in disturbed environments. This study aimed to investigate the survival and growth patterns of native forest species from different ecological groups growing in a modified area of Amazonas. The experiment was installed in randomized blocks design with eleven species (six pioneers species -P and five no pioneers species -NP), five repetitions and 3 × 2 m spacing. After ten months of cultivation, the survival rates observed exceeded 80% for most species in different ecological groups, except for the species Sclerolobium paniculatum (40%) and Cedrela odorata (67%
