“…Also, using native species in plantations could decrease the concern of adaptation and being infected the pests and diseases. The study on plantation in Iran and the other part of the world was extended in recent decades (Abdy and Mayhead 1992;Allen et al 1995;Menalled et al 1998;Ferris et al 2000;Coroi et al 2004;Lindenmayer and Hobbs 2004;Yamashita et al 2004;Lee et al 2005;Lemenih and Teketay 2005;Pourbabaei et al 2005;Corney et al 2006;Ginsberg 2006;Mosayeb Neghad et al 2007;Pourbabaei and Roostami Shahraji 2007;Poorbabaei and Poorrahmati 2009).…”

Pourbabaei H, Asgari F, Reif A, Abedi R. 2012. Effect of plantations on plant species diversity in the Darabkola, Mazandaran Province,. In this study, the effect of plantations on plant species diversity was investigated in Darabkola, Mazandaran province, north of Iran. To conduct the study, a natural mixed forest, a broad-leaved plantation (Alnus subcordata-Acer velutinum) and a coniferous plantation (Cupressus sempervirens var. horizontalis-Pinus brutia) were selected. 35 sampling plots were taken in systematic random method in each area. Data analysis was carried out using Simpson, Hill's N 2 , Shannon-Wiener and Mc Arthur's N 1 diversity indices, Smith and Wilson evenness index and species richness. Results revealed that there were 32 plant species in natural forest and 30 plant species were found in each plantation. Rosaceae and Lamiaceae were the main families in the studied areas. Diversity and evenness indices of all vegetation layers had the most values in the natural forest. Richness of woody plants had the highest value in the natural forest, while herbaceous richness was the highest in coniferous plantation. Mc Arthur's N1 had the highest value among diversity indices and followed by Hill's N 2 , Shannon-Wiener and Simpson indices, respectively. In addition, results showed that there were significant differences among diversity, evenness and richness indices in all vegetation layers in the three studied areas.

“…Para efeito de comparação, um plantio de C. japonica aos 22 anos de idade e 1.200 indivíduos.ha -1 , localizado na região central do Japão, com temperatura média anual de 14 °C e precipitação de 1.900 mm, apresentava DAP médio de 24,6 cm (YAMASHITA et al, 2004). Embora haja uma diferença de 9 anos entre o trabalho citado acima e o presente estudo, verifica-se certa similaridade de ritmo de crescimento diamétrico entre o local de origem e o observado no teste de procedência na EE Rio Negro.…”

“…Uma das coníferas comerciais mais importantes na Ásia (TAKATA; TERAOKA, 2002;SHYUR et al, 2008), Cryptomeria japonica é originária da região temperada do Japão, onde é conhecida como 'Sugi' (CARPANEZZI; CARVALHO, 1988) e amplamente plantada (YAMASHITA et al, 2004;ZHU et al, 2005), principalmente em regiões montanhosas (TAKATA; TERAOKA, 2002), ocupando, aproximadamente, 45% das plantações florestais naquele país, de um total de 10 milhões de hectares (OHBA, 1993). Na área de distribuição natural, a espécie ocorre naturalmente entre 600 e 1.800 metros de altitude, em clima caracterizado por invernos frios, com ocorrência de neve e verões moderadamente quentes (CARPANEZZI; CARVALHO, 1988).…”

“…Shimizu e Maiochi (2007) confirmam a sensibilidade da espécie à qualidade do sítio. Segundo EMBRAPA (1988), suas exigências edáficas são equivalentes ou superiores às do pinheiro-do-paraná, fato este confirmado em seu local de origem por Yamashita et al (2004), que relatam ser um espécie plantada apenas nos sítios mais férteis em função das suas exigências.…”

Cryptomeria japonica é originária da região temperada do Japão, onde é amplamente plantada em função da alta durabilidade e trabalhabilidade da madeira. O objetivo do presente trabalho foi avaliar o desempenho de procedências japonesas de C. japonica, implantadas em 1980 na Estação Experimental da Universidade Federal do Paraná, município de Rio Negro, Paraná. Realizou-se levantamento dendrométrico em setembro de 2011, o qual serviu de base para as análises estatísticas e genéticas. A produtividade observada aos 31 anos variou de 9,3 m³.ha-1.ano-1 na testemunha (Camanducaia), até 22,2 m³.ha-1.ano-1 na procedência Miyagi. A partir dos resultados, foram propostas estratégias de melhoramento genético para a criação de uma Área de Produção de Sementes (APS) e um Pomar Clonal de Sementes (PCS), bem como a seleção de indivíduos superiores para reprodução assexuada. Para tal, considerou-se uma intensidade de seleção que mantivesse ao máximo a variabilidade genética entre procedências, mas explorasse a variação dentro de cada procedência. As sementes produzidas terão um ganho no crescimento diamétrico estimado em 9,2% para a APS (curto prazo) e de 14% para o PCS (médio prazo). AbstractA proposal for the existing germplasm of Cryptomeria japonica (L.F.) Don. at the Experimental Station of Rio Negro, PR, aiming at the production of genetic improved seeds. Cryptomeria japonica is indigenous to the temperate region of Japan where it is widely planted, due to its wood quality, high durability and workability. The aim of this study was to evaluate the performance of Japanese provenances of C. japonica, established in 1980 at Experimental Station of Parana Federal University, municipality of Rio Negro, Parana State. Dendrometric measurements were carried out in September 2011, which was the basis for statistical and genetic analysis. The productivity at age 31 years ranged from 9.3 m³.ha-1.year-1 (control), up to 22.2 m³.ha-1.year-1 (Miyagi). A breeding strategy was proposed based on a seed production area (SPA) and on a clonal seed orchard (CSO). Moreover superior individuals for vegetative reproduction were also selected. The selection intensity was suggested considering the maintenance of expressive genetic variability among provenances, but exploring the variation within each provenance. The estimated genetic gain for diameter growth was 9.2% for the SPA (short term) and 14% for the CSO (medium term).Keywords: Forest breeding; seed production area; clonal seed orchard.

“…Soil N status could cause a change in plant nutrient regime, which might result in a change in foliar lignin:N ratio, followed by a change in the C:N ratio in the forest floor. Consequently, these changes would affect N mineralization and nitrification which could result in increasing soil N availability (Yamashita, et al, 2004) and in great potential for N export (Borken and Matzner, 2004;Zhang et al, 2010b).…”

In order to reveal the effects of nitrogen (N) deposition on forest ecosystems, we investigated the soil N dynamics across a chronosequence of subtropical evergreen broad-leaved forest stands in eastern China for two years. Current atmospheric N deposition was 18 kg ha -1 year -1 . Nitrogen fluxes in throughfall varied from 17 to 23 kg hawith an increasing trend with stand age. The total N fluxes ranged from 7.3 to 9.3 kg ha -1 year -1 under the forest floor and from 1.2 to 2.5 kg ha -1 year -1 at 30-cm soil depth with the high values in the older stand. The net mineralization potentials in the old stands ranged from 19 to 24 mg kg -1 month -1 , and were 30-55% higher than those in the young stands. The inorganic N concentration and flux at 30-cm soil depth were significantly (p < 0.05) correlated with net mineralization potential. The potential N transformation rates were significantly (p < 0.05) correlated with soil C/N ratio and DON while not with forest floor C/N ratio. Input-output budget suggests that the forest at our site is a finer buffering system to N deposition and is far from N saturation.
