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 ...
Seedling survival of Handroanthus impetiginosus (Mart ex DC) Mattos in a semi-arid environment through modified germination speed and post-germination desiccation tolerance
(Int Inst Ecology, 2015-11-01)
Uniform rapid seed germination generally forms a great risk for the plant population if subsequent intermittent precipitation causes desiccation and seedling death. Handroanthus impetiginosus can be found commonly in a ...
Acceleration in germination sensu stricto plays a central role on seedling vigor in post-germination
(2021-10-01)
An obvious relationship between germination sensu stricto and seedling development during post-germination has been considered, but not explained concerning vigor. Taking this into account, we used measurements of water ...
Fire cues trigger germination and stimulate seedling growth of grass species from Brazilian savannas
(2019-01-01)
Premise: Although fire cues (high temperatures and smoke) influence seed germination in numerous species from fire-prone environments, their effects on seed germination of species from neotropical savannas are poorly ...
Infection of guava by Colletotrichum gloeosporioides and Colletotrichum acutatum under different temperatures and wetting periods
(SOC BRASILEIRA FITOPATHOLOGIA, 2008)
Anthracnose, caused by Colletotrichum gloeosporioides and C acutatum, is one of file main post-harvest diseases in guavas. This study aimed to determine the influence of environmental variables oil germination and appressorium ...
Are wildfires affecting seed germination in cactus? An experimental assessment
(Wiley Blackwell Publishing, Inc, 2021-03-11)
Cacti are conspicuous plants across arid and semi-arid ecosystems of the American continent and are currently under threat due to human pressures, such as habitat loss, illegal collection and changes in fire regimes. ...
Germination response of common annual and perennial forbs to heat shock and smoke treatments in the Chaco Serrano, central Argentina
(Wiley Blackwell Publishing, Inc, 2018-08)
Fire is a key ecological factor affecting plant dynamics. In the last few decades, fire occurrence in the Chaco region has increased noticeably, challenging the adaptive capacity of plants to regenerate after a fire. ...
What happens when the rain is back? A hypothetical model on how germination and post-germination occur in a species from transient seed banks
(Public Library Science, 2020-02-26)
We hypothesize that by simulating the natural priming in seeds of a species that forms transient seed banks it is possible to clarify molecular aspects of germination that lead to the recruitment of seedlings when the next ...
Seed morphology and post-seminal development in species of Comanthera (Eriocaulaceae)
(Revista De Biologia Tropical, 2015-12-01)
Comanthera brasiliana, C. magnifica and C. suberosa (Eriocaulaceae) are included in the Brazilian list of endangered species, due to intensive harvest and micro-endemism. These species form the Glade of Comanthera magnifica, ...

(2015-01-01)
Comanthera brasiliana, C. magnifica and C. suberosa (Eriocaulaceae) are included in the Brazilian list of endangered species, due to intensive harvest and micro-endemism. These species form the clade of Comanthera magnifica, ...
