Germination constraints of dicarpic cypselae of Bidens pilosa L.Restrições a germinação de cipselas dicárpicas de Bidens pilosa L.
(2019-01-01)
Bidens pilosa L. is a heterocarpic weed species with two cypselae types that present morpho-physiological differences, being the peripheral type smaller and slower to germinate than the central one. We aimed to verify how ...
The role of pericarp in Bidens L. heterocarpy (Asteraceae)
(Elsevier B.V., 2019-08-01)
Diaspore heteromorphism is a common reproductive strategy in Asteraceae. The genus Bidens L. contains some species with two or more types of cypselae in a single capitulum, with dicarpy being more frequently observed. Our ...
Sensitivity to hypoxia and microbial activity are instrumental in pericarp-imposed dormancy expression in sunflower (Helianthus annuus L.)
(Cambridge University Press, 2019-04)
We used two sunflower genotypes displaying pericarp-imposed dormancy at high incubation temperatures (i.e. 30°C) to investigate the role of the pericarp as a limitation to oxygen availability to the embryo (hypoxia), and ...
Avaliação bioquímica nutricional de cultivares de arroz

Effect of Punica granatum (pomegranate) on sperm production in male rats treated with lead acetate.
(Taylor and Francis, 2011)
The present study was designed to determine whether the treatment with an ethanolic extract of pomegranate (EEP) (Punica granatum) can be useful for the treatment of the deleterious effect of lead acetate (LA) administration ...

Fisiologia da germinação das cipselas heteromórficas em Bidens L
(Universidade Estadual Paulista (Unesp), 2014-09-30)
Bidens is an Asteraceae genus that presents heteromorphic cypsela which differ in the germination behavior. For the genus, the pattern is that the peripheral cypselae have lower germination rate than the central ones. The ...
Dihydrochalcones and flavonolignans from Iryanthera lancifolia
(Amer Chemical Soc, 1999-11-01)
An extract from the pericarps of I. lancifolia afforded two dihydrochalcones (1 and 2) and two flavonolignans (3 and 4), with compounds 2-4 being of novel structure. The antioxidant activities of compounds 1-4 were evaluated ...
