SHADING LEVELS AND PLANT GROWTH REGULATOR FOR FORMATION OF SCHIZOLOBIUM AMAZONICUM COMPACT SEEDLINGS [PDF]
Engenharia Agricola, 2019 ABSTRACT Paricá (Schizolobium amazonicum) can be used for rehabilitation of degraded lands, timber manufacturing markets. However, for its planting, high-quality seedlings should be used. Thus, this study aimed to evaluate the effect of different types of paclobutrazol (PBZ) application and two shading levels on high-quality seedling production.

Respostas de plantas de Schizolobium amazonicum [S. parahyba var. amazonicum] e Schizolobium parahyba [Schizolobium parahybum] à deficiência hídrica [PDF]
Revista Arvore, 2005 Plantas jovens de S. amazonicum (paricá) e S. parahyba (guapuruvu) foram submetidas a dois ciclos de deficiência hídrica em casa de vegetação. O déficit hídrico induziu o aumento dos teores de aminoácidos solúveis totais, prolina, açúcares solúveis totais e K+ nos tecidos foliares, ocasionando o abaixamento do potencial osmótico em ambas as espécies ...
