1. Respostas funcionais foliares de plantas jovens de Hevea brasiliensis submetidas à deficiência hídrica e à reidratação
Resumo A deficiência hídrica é considerada um fator que produz danos significativos durante o período de estabelecimento e de crescimento dos plantios. O objetivo deste estudo foi investigar características morfofisiológicas e bioquímicas de folhas de mudas de seringueira em resposta à deficiência hídrica e, posterior, reidratação. Plantas jovens

2. Changes in carbohydrates accumulation in Viguiera discolor Baker in response to water deficit
RESUMO O estresse hídrico é um fator ambiental que pode regular o crescimento, limitando a produção e levando a alterações fisiológicas e bioquímicas. Plantas apresentam uma série de respostas adaptativas a seca, tal como ajustamento osmótico, nos quais os carboidratos desempenham um importante papel. Avaliamos a influência do déficit hídrico no

3. The Role of Free Proline and Soluble Carbohydrates in Water Gypsum Stress on Some Gypsophyte and Gypsovag Plants
RESUMO: O objetivo deste estudo é investigar o papel da prolina livre e dos carboidratos solúveis em condições de estresse gesso. Inicialmente, foram analisadas as prolinas e carboidratos contidos em gipsita e gipsovaque. Prolinas são compostos que contêm nitrogênio, produzidos sob condições de estresse, com propriedades de proteção e que contribu

4. Utilization of a novel feedstuff: effects of additives on the fermentation characteristics, chemical composition and in vitro digestibility of tetraploid black locust (Robinia pseudoacacia) silage
RESUMO: Este estudo foi conduzido para avaliar os efeitos de aditivos nas características de fermentação, composição química e digestibilidade in vitro do gafanhoto preto tetraplóide (TBL). A silagem de folhas TBL não foi tratada (controle) ou foi tratada com 1 × 106 ufc / g FM Lactobacillus plantarum (L), 1% glicose (G), 3% melaço (M), uma combin

5. New inoculants on maize silage fermentation
The objective of this study was to evaluate the effect of bacterial inoculants at two inoculation rates on chemical and biological characteristics of maize silage. The treatments consisted of two inoculating rates (5 and 6 log cfu g-1 of forage) for each strain of lactic acid bacteria (LAB) identified as Lactobacillus buchneri, L. hilgardii, or L. plantarum.

6. The chemical composition, fermentation profile, and microbial populations in tropical grass silages
The objective of this study was to evaluate the fermentation profile, chemical composition and microbial population and losses in the silages of signalgrass and Mombasa grass fertilized with the following levels of nitrogen (N): 0, 30, 60 and 90 kg/ha. The grasses were harvested at 70 days of regrowth, chopped and then ensiled in laboratory silos that had 20

7. Chlorophyll and carbohydrates in Arachis pintoi plants under influence of water regimes and nitrogen fertilization
In this experiment the chlorophyll and carbohydrate contents of Arachis pintoi were evaluated to verify if the presence of nitrogen in the soil could contribute to the effectiveness of the establishment of this legume. The design was completely randomized, in a 4 × 4 factorial arrangement, with four N rates (0, 40, 80 and 120 kg ha-1) and four irrigation le

8. A simple procedure for the purification of active fractions in aqueous extracts of plants with allelopathic properties
Most studies conducted to test the allelopathic activity of plant parts have made use of water as solvent. However, the presence of polar, water-soluble substances, such as proteins and carbohydrates, tends to hamper the purification of active compounds. In this study, we present a simple purification procedure that separates the active fraction of the extra

9. Physiological and biochemical responses to drought stress in Barbados cherry
To evaluate physiological genotypic differences between two Barbados cherry genotypes (13- and 14-CPA) under water deficit, initial growth, water relations, and organic solute accumulation were evaluated in an experiment performed using four-month-old seedlings, which were subjected to four water treatments (100, 75, 50, and 25% of field capacity), with five

10. Capacity of ensilage of Jatropha curcas L. cake to degrade forbol esters
The objective of this study was to evaluate the capacity of the ensilage of Jatropha curcas L. expeller cake to reduce the phorbol esters and its effect on fermentative losses, by adding soluble carbohydrates or microbial inoculants. The design was completely randomized with four replications in a 3 × 2 factorial arrangement, with three sources of soluble c

11. Desenvolvimento e respostas fisiológicas de mudas de cafeeiro parasitado por Meloidogyne exigua e M. paranaensis / Development and physiological responses of seedlings of coffee parasitized by Meloidogyne exigua and M. paranaensis
The nematodes of the genus Meloidogyne are responsible for the largest losses in coffee crop. M. exigua is the most widespread species in coffee area and causes large losses, but M. paranaensis, the most aggressive species, can derail the coffee crop in infested areas. Under field conditions has been observed that the coffee is more tolerant to M. exigua par

12. Avaliação do potencial da casca de Eucalyptus spp. para a produção de bioetanol / Evaluation of the potential use of Eucalyptus spp. bark for bioethanol production
The use of no fossil source for biofuels production has been stimuled in the all world. Proposing a new global scenario related to the energy matrix, together with the environmental conditions, there is the need to search alternative renewable raw materials. In this context, Brazil presents special conditions, considering the lignocellulosic residues from th
