Genetic divergence among slash pine second generation progenies at an early age
Pagliarini, Maximiliano Kawahata; Kieras, Wesllen Schuhli; Moreira, Juliana Prado [UNESP]; de Sousa, Valderes Aparecida; Shimizu, Jarbas YukioMade available in DSpace on 2021-06-25T10:13:49Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; The objective of this study was to estimate the genetic divergence among slash pine open-pollinated progenies at an early age. Two progeny tests were established in a randomized complete block design, single-tree plots planted in March, 2009, in a 3 x 3.0 m spacing. One test was planted in Ribeirão Bran...
Expected gain in selection of Pinus elliottii var. elliottii for timber product...
Moreira, Juliana Prado; Shimizu, Jarbas Yukio; Sousa, Valderês Aparecida; Moraes, Mario Luis Teixeira de; Moura, Nara FernandesP. elliotii var. elliottii is the second most planted fast growing tree species in Brazilian subtropics for wood and resin production. The objective of this work was to predict genetic values of fast growing individual trees. A trial was established in a randomized complete blocks design involving 76 treatments, 75 open pollinated progenies from a clonal seed orchard and a commercial progeny as control, in a 3 ...
Sweetgum for wood production in the South and Southeastern Brazil
Shimizu, Jarbas YukioSweetgum is a North and Central American tree species well known for the healing gum since the times of the Aztec civilization. In the southern United States, this is the most widely planted broadleaf species for wood production. It grows well on a variety of site conditions, including on alluvial soil prone to flooding. As a result of the wide natural distribution, it shows important variations in phenology ...
Genetic selection Pinus greggii progeny to the establishment of seed orchards
Aguiar, Ananda Virgínia de; Sousa, Valderês Aparecida de; Shimizu, Jarbas YukioThe main deterrent to the adoption of new species for operational plantations is the availability of genetically improved seeds in sufficient amount to supply the market. Therefore, this study was carried out with the objective to estimate genetic parameters for individual selection as a basis to transform the field trial into a seedling seed orchard. The trial contained forty seven half-sib families from fiv...
A complementary strategy for the conservation of native forest tree species: re...
Shimizu, Jarbas YukioDeforestation has become rampant in recent years in Brazil and has affected all biomes where manyspecies are threatened to extinction due to destruction natural habitats. Government initiatives to hinder thechain of destruction include two main lines of action: to establish conservation units (parks, reserves andothers); and programs to encourage plantation of native tree species for reclamation of degraded eco...
Japanese red cedar as an alternative species for wood production in the State o...
Shimizu, Jarbas Yukio; Maiochi, Riceli AntunesJapanese red cedar (Cryptomeria japonica (L. F.) D. Don.) is an important alternative tree species forwood production in the State of Paraná. This study reports on the performance of this species from different geographic origins in comparison to a previously introduced population of unknown origin. The test plantations were established in three locations in the State of Paraná. The sites differed in soil types...
Assessment of Eucalyptus species and provenances for planting in the northweste...
Quiqui, Erci Marcos Del; Martins, Sueli Sato; Shimizu, Jarbas YukioReforestation to cope with growing demand of wood and to minimize the pressure in remnant natural forests is extremely important. Twelve species from different sites were planted in 49 plots in 3 m x 2 m spacing in randomized complete blocks design with four replications, on the Tamanduá Experimental Farm in Campo Mourão to identify the most productive species of Eucalyptus (Myrtaceae) and their provenance, in ...
Evaluation and genetic progress in volume of grevilea provenances at three diff...
Martins, Emerson Gonçalves; Neves, Edinelson José Maciel; Shimizu, Jarbas Yukio; Ferreira, Carlos AlbertoTwenty one provenances of Grevillea robusta Cunn were tested at Nova Esperança and Quedas do Iguaçu, Paraná state and Anhembi, São Paulo state, Brazil. With the aim of comparing the performance of the original provenances with the comercial provenance collected in Maringa, Paraná state included as a control. Provenance trials were installed in a randomized block design with rectangular plots, each one with six ...
