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 ...
Germination traits of the cypselas on the native Hyalis argentea (Asteraceae)
(Nova Science Publishers, 2013)
The germination requirement of native species are key factors in the ecological restoration of degraded ecosystem. A variety of plant seeds are affected by dormancy. Therefore, the knowladge of processes and enviromental ...

Germination of stored and scarified seeds of Passiflora caerulea L. (Passifloraceae)
(Taylor & Francis, 2009-10-20)
This work evaluates the influence of storage and scarification in the germination of Passiflora caerulea L., in order to acquire the necessary knowledge to cultivate this economically important species. Seeds stored one ...
Alternating temperature combined with darkness resets base temperature for germination (Tb) in photoblastic seeds of Lippia and Aloysia (Verbenaceae)
(Wiley Blackwell Publishing, Inc, 2017-01)
Thermal time models for seed germination assume a continuum of rate responses in the sub-optimal temperature range. Generally, the models describe germination performance in non-dormant seeds at constant temperatures, ...
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 ...
Study of spore germination in Thelypteris-dentata (forssk) e-st-john
(Inst Tecnologia Parana, 1992-01-01)
The spore germination in Thelypteris dentata was studied and the optimum temperature of 25 C was determined by the maximum percentage germination and the highest germination index. The necessity of continuous white light ...

Effect of temperature on seed germination of ornamental herbaceous perennials
(2013-07-15)
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 ...
