1. USE OF BENCHES WITH REFLECTIVE MATERIAL TO FAVOR PRODUCTION OF RUBBER TREE ROOTSTOCK SEEDLINGS
ABSTRACT Success in production of any perennial tree depends on the use of high-quality seedlings. This study aimed to evaluate cultivation benches with reflective material and protected environments for production of rubber tree rootstock seedlings. The experiments were conducted in two types of protected environments: 35% shading aluminized screen and 30%

2. Gênero Cryptostegia: fitoquímica, atividades biológicas e aplicações industriais
The genus Cryptostegia comprises two species, C. madagascariensis (Bojer) and C. grandiflora (Roxb. Ex R. Br) that belong to the Apocynaceae family and are widely distributed in the tropics, as in Australia, New Zealand, India and Brazil, where they cause great socioeconomic and environmental damage, as they are invaders causing damage, mainly in the cultiva

3. [PROVISIONAL] Identification of histone methylation modifiers and their expression patterns during somatic embryogenesis in Hevea brasiliensis
Abstract Histone methylation plays a crucial role in various biological processes including from heterochromatin formation to transcriptional regulation. Currently, no information is available regarding histone methylation modifiers in the important rubber-producing plant Hevea brasiliensis. Here, we identified 47 histone methyltransferase (HMT) genes and 25

4. Defense responses to Meloidogyne exigua in resistant coffee cultivar and non-host plant
The resistance of coffee plants to Meloidogyne exigua is conferred by the gene Mex-1. However, the mechanisms of resistance still need to be clarified. Therefore, the penetration, development and reproduction of two populations of M. exigua (M1, isolated from the coffee plant and M2, from rubber tree) in susceptible (Coffea arabica 'Catuai') and resistant (C

5. Phlebotonics for haemorrhoids
BACKGROUND Haemorrhoids are variceal dilatations of the anal and perianal venous plexus and often develop secondary to the persistently elevated venous pressure within the haemorrhoidal plexus. Phlebotonics are a heterogenous class of drugs consisting of plant extracts (i.e. flavonoids) and synthetic compounds (i.e. calcium dobesilate). Although their preci

6. Melhoria das propriedades do gesso com aditivo sintético e com látex de euphorbia tirucalli e de hevea brasiliensis para uso na construção de habitações de interesse social.
Um dos grandes desafios da humanidade é utilizar o ambiente em que vive de forma racional, de modo a não comprometer a sua existência nem a das gerações futuras. Toda atividade de construção e de ocupação de áreas gera um impacto ambiental que pode ser irreversível, exaurindo recursos naturais ou contaminando a terra, o ar ou os cursos dágua. O t

7. Producción y propiedades químicas del caucho en clones de Hevea según los estados fenológicos
The objective of this work was to evaluate the yield performance and macronutrient content of rubber extracted from four Hevea brasiliensis clones, under different tapping systems and plant phenological stages. The experiment was carried out in the 2010 and 2011 crop seasons, in a split‑plot randomized complete block design, with four replicates. The main

8. Selectivity of the plant growth regulators trinexapac-ethyl and sulfometuron-methyl to cultivated species
The aerial spraying of plant ripeners on sugar cane (Saccharum officinarum L.) crops causes often the contamination of neighboring areas, which subsidizes formal complaints from the neighbors. These contaminations are due to spraying taking place during inadequate environmental conditions or from technical mistakes during the application. One of the most imp

12. Tropical terrestrial model ecosystems for evaluation of soil fauna and leaf litter quality effects on litter consumption, soil microbial biomass and plant growth.
Abstract ? The aim of this work was to evaluate whether terrestrial model ecosystems (TMEs) are a useful tool for the study of the effects of litter quality, soil invertebrates and mineral fertilizer on litter decomposition and plant growth under controlled conditions in the tropics. Forty-eight intact soil cores (17.5-cm diameter, 30-cm length) were taken o
