Abstract

El presente articulo evaluo el efecto bioestimulante de Trichoderma harzianum Rifai en la produccion de postura de Leucaena leucocephala (Lam) de Wit., Cedrela odorata L. y Albizia saman (Jacq.) Merr. Se desarrollaron tres experimentos en condiciones de vivero, uno para cada especie. Se empleo un diseno completamente aleatorio con cuatro parcelas por tratamiento. En cada experimento los tratamientos fueron: Trichoderma harzianum a razon de 20 g.L -1 , 40 g.L -1 y un testigo. Se evaluo el porcentaje de germinacion y las variables morfometricas diametro y altura del tallo, asi como biomasa seca en raiz y parte aerea de la planta. Los tratamientos con Trichoderma no incrementaron el porcentaje de germinacion en cedro, saman y leucaena. T. harzianum incremento la altura, el numero de hojas y la biomasa seca del area foliar en las plantulas de cedro, mientras que en leucaena y saman solo provoco incrementos del diametro basal de las plantulas.

Harzianum Rifai木霉对银合欢、雪松和萨满姿势的生物刺激作用

本文评价了木霉Harzianum rifai对银合欢（Leuceana leucocephala，LAM）生长体位的生物刺激作用。，Cedrela Odorata L.和Albizia Saman（Jacq.）梅尔。在苗圃条件下进行了三次实验，每个物种一次。采用完全随机的设计，每个处理有四个地块。在每个实验中，处理方法为：哈茨木霉20g.L-1、40g.L-1和1个对照。评估了植物的发芽率、茎直径和高度的形态计量变量以及根和地上部的干生物量。木霉处理并没有增加雪松、萨曼和银合欢的发芽率。T、 Harzianum增加了雪松幼苗的高度、叶数和叶面积的干生物量，而在银合欢和萨满，它只会导致幼苗基径的增加。

期刊介绍： Colombia Forestal Journal publishes original manuscripts on themes of the forest field and various aspects of natural resources and the environment, which are discriminated in the categories of research article, review, reflection and technical notes of agreement with the stipulations of COLCIENCIAS for scientific publications. According to the classification of scientific areas of the Organization for Economic Cooperation and Development (OECD), Colombia Forestal Journal belongs to the large area of Agricultural Sciences (4), Agriculture, Forestry and Fisheries (4A) and to the discipline Forestry (4A02). Since its creation in 1978, the journal has been edited and published by the Francisco José de Caldas District University with headquarters in Bogotá. The quality of the content of the journal has been strengthened with the collaboration of national and international external evaluators in a double blind arbitration system and the dissemination has been extended by publishing manuscripts in a language different from Spanish and with inclusion in bibliographical databases such as Scopus. , DOAJ, Scielo, Redalyc, Ebsco, CAB Abstracts of CAB International, Forestry Abstracts, Ulrich''s, Latindex, Publindex. Likewise, it has academic profiles at Mendeley, Academia and Researchgate. The articles that are submitted to Colombia Forestal Journal must be original and unpublished and have not been postulated in other journals.
