Effect of temperature on seed germination of ornamental herbaceous perennials
Antirrhinum majus L. and Senecio douglasii DC. are herbaceous perennial ornamental plants used in landscaping. The multiplication of these plants is by seed; however, there are still doubts about the temperature that can ...
Eco-physiological aspects of melaleuca seed germination
The invasive behavior of melaleuca (Melaleuca quinquenervia) plants in wetlands is due to its aggressive regeneration strategy, which is based on its seeds germination performance. Understanding of the eco-physiological ...
Longevity of seeds and soil seed bank of the Cerrado tree Miconia chartacea (Melastomataceae)
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 ...
Influence of light quality on germination and initial growth of canephori seedlings Peltophorum dubium (Sprenge) Taub.
(Wfl Publ, 2012-07-01)
Light is considered one of the major environmental factors controlling germination of different species, mainly native ones, based on the importance of the species Peltophorum dubium for re-vegetation of degraded areas, ...
Temperature and scarification on seeds germination of copernicia prunifera (Mill) H.E. Moore (Arecaceae)
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 ...
Analysis of seed-germination in Piptadenia-Gonoacantha (Mart) MACBR (Leguminosae Mimosoideae)
(Inst Tecnologia Parana, 1994-01-01)
Preliminary tests indicated 20-degrees-25-degrees-C as optimum temperature range to the germination of the seeds of P. gonoacantha. Seeds germinate both under light and dark conditions, although final percentage is always ...
The effect of simulated heat-shock and daily temperature fluctuations on seed germination of four species from fire-prone ecosystems
(Soc Botanica Brasil, 2016-07-01)
Seed germination in many species from fire-prone ecosystems may be triggered by heat shock and/or temperature fluctuation, and how species respond to such fire-related cues is important to understand post-fire regeneration ...
