Abstract

Parkia multijuca Benth . is one of the Forest species that occurs in the Amazon region. The aim of the this study was evaluate the development of seedlings of Parkia multijuga in differents shading and container volume in nursery. The experimental design was a randomized block design in 4 x 4 subplotplot (4 shadings and 4 containers volumes). The shading was 0, 30, 50 and 70% and containerv olumes 110, 180, 290 and 400 cm³. The diameter, root drymass, shootdrymass, total dry mass and the Dickson quality index of the seedlings increased proportionally with container volume and with the availability of light. The conduction of the seedlings in full sun and container volume 400 cm³ favors the development of P. multijuga quality seedlings and 70% shading should not be used in nurseries to produce P. multijuga seedlings.

multijuga公园底部的容器体积和遮阳。苗圃繁殖

白头翁是亚马逊地区的一种森林物种。研究了不同遮荫条件和不同容器容积条件下青松幼苗的发育情况。实验设计为随机区组设计，分为4 × 4个亚区(4个阴影区和4个容器区)。遮阳分别为0、30、50和70%，容器容积分别为110、180、290和400 cm³。幼苗直径、根干质量、枝干质量、总干质量和Dickson质量指数随容器容积和光照利用率成比例增加。在充分日照和容器容积为400 cm³的条件下进行幼苗传导有利于多刺麻优质苗的发育，苗圃不宜采用70%遮荫来生产多刺麻幼苗。

期刊介绍： The Iheringia, Série Botânica is a publication edited by the Museu de Ciências Naturais, Fundação Zoobotânica do Rio Grande do Sul, since 1958. The name Iheringia is actually a tribute to Hermann von Ihering (a German researcher who became a Brazilian citizen) and his important studies in the Natural Sciences.The journal has the mission of publishing articles, reviews and original scientific notes that cover diverse areas in Botany, and may be written in Portuguese, Spanish and English. The journal is widely available in both international and national scientific community. The issues are published and distributed twice a year to 118 national institutions and 152 international institutions. The distribution is either free of charge or by exchange.
