Temperature Dependent Seed Germination of Dalbergia nigra Allem (Leguminosae) [PDF]

Brazilian Archives of Biology and Technology, 2001
The germination of endangered species Dalbergia nigra was studied and 30.5° C was found as optimum temperature, although the species presented a broad temperature range where germination occurs and light had no effect.

In vitro organogenesis as an efficient method for the propagation of Dalbergia nigra

Pesquisa Agropecuaria Brasileira, 2022
The objective of this work was to establish an efficient protocol for the in vitro organogenesis of Dalbergia nigra. For this purpose, 30-day-old seedlings were sectioned at their cotyledonary nodes and nodal segments.

Environmental and Plant Variables Influence Dalbergia nigra (Fabaceae) Phenology - Implications for Seed Production [PDF]

Floresta e Ambiente, 2022
Studies of plant phenology in the Atlantic Forest can be enhanced by a greater understanding of the factors regulating vegetative and reproductive cycles. Dalbergia nigra (Vell.) Allemão ex Benth. is endemic and vulnerable in the Atlantic Forest.

Production of reactive oxygen species in Dalbergia nigra seeds under thermal stress [PDF]

Journal of Seed Science, 2014
Seed germination is dependent on abiotic factors, temperature being one of the main ones, whose influence causes seed damage under extreme conditions. The aim of the present study was to investigate the effect of different temperatures during germination

"Touch&Play" Wood Typification by the MasSpec Pen. [PDF]

J Mass Spectrom
ABSTRACT We have investigated the ability of a MasSpec Pen (MSPen) “three‐in‐one” (extraction, transfer, and ionization) device coupled to a mass spectrometer to provide instantaneous chemical profiles that could promptly characterize wood samples from the mahogany (Meliaceae) family.

Nesting on Cell Phone Towers: An Inexplicable Breeding Strategy by Asian Woollynecks <i>Ciconia episcopus</i> in Bangladesh. [PDF]

Ecol Evol
In this paper, we documented some crucial nesting and breeding information on Asian Wollynecks. We used camera traps as a means of passive monitoring and identified Large‐billed crow Corvus macrorhynchos and House crow Corvus splendens as potential nest predators.

Liquiritigenin-Rich Hydroalcoholic Extract of Brazilian Red Propolis Reduces Dyskinesia Induced by 3,4- Dihydroxyphenylalanine in Hemiparkinsonian Rats. [PDF]

Basic Clin Pharmacol Toxicol
ABSTRACT The set‐up and progression of dyskinesia induced by 3,4‐dihydroxyphenylalanine (L‐DOPA) are strongly linked to oxidative stress and neuroinflammation. The aim of this work was to study and characterize the effects of the hydroalcoholic extract of Brazilian red propolis (HERP) on L‐DOPA–induced dyskinesia (LID) in hemiparkinsonian rats injected

Prevalence of Contact Allergy to Propolis-Testing With Different Propolis Patch Test Materials. [PDF]

Contact Dermatitis
ABSTRACT Introduction Propolis is a sticky substance produced by honeybees from plant resins collected from locally growing vegetation. Its chemical composition varies depending on the plant species visited by the bees. Contact dermatitis is commonly reported following exposure to cosmetics containing propolis or following the intake of food ...
