Longevity of seeds and soil seed bank of the Cerrado tree Miconia chartacea (Melastomataceae)
(2015-12-01)
Miconia chartacea is a widely distributed tree in Brazil, occurring at altitudes ranging from 300 m to 1900 m in the Caatinga, Cerrado and Atlantic Forest biomes. In this work we attempted to classify M. chartacea seeds ...
Effect of pre-germinal treatment and temperature on the germination of achenes of Baccharis dracunculifolia DC
(2019-01-01)
The species Baccharis dracunculifolia, known as alecrim-do-campo is very rough, of great economic importance, recommended for recovery of degraded areas, but is little explored by propagation through seeds. In order to ...
Storage in cerrado soil and germination of Psychotria vellosiana (Rubiaceae) seeds
(2006-08-15)
The regeneration of plant communities from seed depends, to a large extent, on the capacity of the seed remaining viable in the soil. The viability and germination of artificially buried Psychotria vellosiana seeds in ...

Temperature and scarification on seeds germination of copernicia prunifera (Mill) H.E. Moore (Arecaceae)
(2013-07-15)
Copernicia prunifera, known as carnauba, is native to Brazil and presents great potential to be used in gardens and cultivation in pot. Palms species, with relatively few exceptions, can only be propagated by seeds; even ...

Effect of tegument integrity on the light sensitivity in seeds of Cucumis anguria L
(Inst Tecnologia Parana, 1996-01-01)
Cucumis anguria present dark germinating seeds at 25 degrees C. Seeds without the tegument are photosensitive germinating better in darkness than under continuous white light. However, pre-incubation at 40 degrees C for ...
Effect of tegumemt integrity on the light sensitivity in seeds of Cucumis anguria L.
(1996-12-01)
Cucumis anguria present dark germinating seeds at 25°C. Seeds without the tegument are photosensitive germinating better in darkness than under continuous white light. However, pre-incubation at 40°C for 48 hours allows ...

PHYTOCHROME CONTROLLED SEED-GERMINATION IN LIGHT INSENSITIVE SEEDS OF RAPHANUS-SATIVUS L CV REDONDO GIGANTE
(Inst Tecnologia Parana, 1992-01-01)
Seed germination of Raphanus sativus is inhibited by light only under low water potential of the medium. Curves of fluence response to white, red and far-red lights demonstrated that the inhibition of seed germination is ...
