Abstract

he objective of this study was to evaluate the grafting of rubber tree seedlings produced on a suspended workbench in full sun, at three different times. One of the major problems in the production of seedlings on a suspended workbench is related to grafting (grafting time and type of bud used). In order to evaluate better times for grafting, an experiment was carried out in a seedling nursery in Mendonça, São Paulo State, Brazil, produced on a suspended workbench in full sun. The design used was randomized blocks, with three grafting times, and for each time, 15 plants were grafted, with four replications. The results were submitted to analysis of variance (ANOVA) and Tukey's test to compare means using a 5% significance level. Grafting index × grafting time was evaluated. There was a significant difference between the grafting time and the grafting index ranged from 68.3% to 95%, depending on the grafting time. It is concluded that climatic factors influence grafting index. Keywords: Graft. Hevea brasiliensis. Clime.

在TRES epicas中，橡胶树幼苗在阳光充足的悬挂台上的嫁接胶指数

本研究的目的是评估橡胶树幼苗在充分阳光下，在三个不同的时间在悬浮工作台上生产的嫁接。在悬挂工作台上生产幼苗的主要问题之一与嫁接有关(嫁接时间和所用芽的类型)。为了评估嫁接的最佳时机，在巴西圣保罗州门多尼帕拉的一个苗圃中进行了一项实验，实验在一个悬挂的工作台上进行，阳光充足。采用随机分组设计，3次接枝，每次接枝15株，4次重复。结果提交方差分析(ANOVA)和Tukey检验，使用5%显著性水平比较均值。评价接枝指数×接枝时间。接枝时间和接枝指数差异显著，接枝时间在68.3% ~ 95%之间。得出气候因素对嫁接指数有影响的结论。关键词:贪污。橡胶树取代巴西橡胶树。气候。

期刊介绍： Nucleus is a fully open access peer-reviewed journal. All articles will (if accepted) be available for anyone to read anywhere, at any time immediately on publication. Aims & Scope: The eukaryotic cell nucleus is more than a storage organelle for genomic DNA. It is involved in critical steps of cell signaling and gene regulation, as well as the maintenance of genome stability, including DNA replication and DNA damage repair. These activities heavily depend on the spatial and temporal “functional” organization of the nucleus and its integration into the complex meshwork of cellular scaffolding. Nucleus provides a platform for presenting and discussing cutting-edge research on all aspects of biology of the cell nucleus. It brings together a multidisciplinary community of scientists working in the areas of: • Nuclear structure and dynamics • Subnuclear organelles • Chromatin organization • Nuclear transport • DNA replication and DNA damage repair • Gene expression and RNA processing • Nucleus in signaling and development Nucleus offers a variety of paper formats including: • Original Research articles • Short Reports • Reviews • Commentaries • Extra Views • Methods manuscripts.
