It is best known under its Peruvian name Iporuru. The leaves are being used as a folk remedy against numerous symptoms associated with pain and inflammation. It has a reputation for being a tonic and booster of male libido. In this study, using a combination of chromatographic techniques, we isolated phenolic constituents present in leaves, and elucidated their structures using MS and NMR techniques. The isolated and characterized compounds were myricetin glucoside, myricetin galactoside, proanthocyanidin A1 and A2, epicatechin, gallic acid, shikimic acid, putranjivain A, elaeocarpusin and never before isolated methyl ester of repandusinic acid A.

Introduction The Euphorbiaceae is a large family including 300 genera and about 5000 species, out of which, the genus Alchornea comprises about 60 species [1]. -
PRE-GERMINATION TREATMENTS of PARICÁ (Schizolobium Amazonicum) SEEDS

Mato Grosso do Sul State University, Cassilândia, MS, Brazil. ABSTRACT: Paricá seeds have dormancy and, even after mechanical scarification, these seeds show slow and uneven germination. Pre-germination treatments can be used to increase seed germination performance. Thus, the aimed to evaluate the physiological potential and initial growth of paricá seeds after pre-germination treatments, using different substances as plant regulators and nutrients, in addition to mechanical scarification. The experimental design was completely randomized, in a 2x7 factorial scheme, consisting of the following pre-germination treatments: mechanical scarification (10% and 50% of the seed coat) and seed pre-soaking [control-water, KNO3 0.2%, Ca(NO3)2 0.2%, gibberellin 0.02%, cytokinin 0.02%, and mixture of gibberellin + cytokinin (1:1)] besides a control group without pre-soaking, with four replicates. The study evaluated germination and emergence rates, germination and emergence speed indices, collar diameter, plant height, seedling dry mass, hypocotyl and seedling length, and electrical conductivity. It was observed that pre-soaking the seeds in gibberellin after mechanical scarification at 50% as a pre-germination treatment resulted in seeds with higher vigor expression and greater initial seedling growth. -

In this chapter, we attempt to describe the major types of vegetation cover in this vast region as they occurred in pre- Columbian times and outline the conditions that support them. Examining the large-scale phytogeographic regions characterized by each major cover type (see Fig. I), we provide basic information on geology, geological history, topography, and climate; describe variants of physiognomy (vegetation structure) and geography; discuss transitions; and examine some floristic patterns and affinities within and among these regions. -

Fire and Legume Germination in a Tropical Savanna: Ecological and Historical Factors

Silveira & 1 Alessandra Fidelis 1Universidade Estadual Paulista (UNESP), Instituto de Biociências, Lab of Vegetation Ecology, Av. 24-A 1515, 13506–900, Rio Claro, Brazil; 2Centro de Investigaciones sobre Desertificación (CIDE/CSIC), C.

E-mail [email protected] • Background and Aims In many flammable ecosystems, physically dormant seeds show dormancy-break pat- terns tied to fire, but the link between heat shock and germination in the tropical savannas of Africa and South America remains controversial. Seed heat tolerance is important, preventing seed mortality during fire passage, and is usually predicted by seed traits. This study investigated the role of fire frequency (ecological effects) and seed traits through phylogenetic comparison (historical effects), in determining post-fire germination and seed mortality in legume species of the Cerrado, a tropical savanna–forest mosaic. • Methods Seeds of 46 legume species were collected from three vegetation types (grassy savannas, woody savannas and forests) with different fire frequencies. Heat shock experiments (100 °C for 1 min; 100 °C for 3 min; 200 °C for 1 min) were then performed, followed by germination and seed viability tests. Principal component analysis, generalized linear mixed models and phylogenetic comparisons were used in data analyses.
