Abstract: Germination of tucumã (Astrocaryum aculeatum G. Mey.) seeds is slow and although the removal endocarp favors speed process, time still considered long. Thus, this study aimed to investigate effects different pretreatment stratification temperatures on germination seeds. Two experiments were set up. The first experiment was conducted using a completely randomized design in factorial sc...

Temperature may affect the mobilization and hydrolysis of storage reserves for energy production during seed germination. This study investigated germination performance reserve in Dalbergia spruceana Benth. seeds incubation at 20, 25, 30, 35, 40°C. The process was favored by 25 to 35°C negatively affected 20 At there reduction speed, however, without significantly compromising final percentage...

Abstract The effects of hydrogel granules mixed with peat substrate on germination, morphological and physiological parameters plugged seedlings were tested in tomato seedlings, at two different irrigation regimes. Due to presence, the germination speed was increased, whereas mean time significantly reduced. Slight improvement recorded regarding final but no effect found synchronisation index s...

Germination experiments with specific germination mutants of Bacillus subtilis, including a newly isolated mutant affected in pressure-induced germination, suggest that a pressure of 100 MPa triggers the germination cascades that are induced by the nutrient germinant alanine (Ala) and by a mixture of asparagine, glucose, fructose, and potassium ions (AGFK), by activating the receptors for alani...

Verbascum yurtkuranianum is a narrow endemic species occurring in single location, the northern Bursa province (Turkey). It an endangered and potentially ornamental plant. No conducted study on its life biology, production, aesthetic features available. This aimed to reveal vegetative properties, seed characteristics, methods requirements for germination, germination speed, potential value so i...

Cratylia argentea is a shrub legume native to tropical regions of South America where it used for animal feed and green manure. In the absence germination guidelines, key aim this study was define most suitable temperature conducting accelerated aging tests. The biochemical attributes seeds were also assessed. Seeds with 10% moisture from 4 different seed lots germinated using between paper met...

Germination timing influences plant fitness, and its sensitivity to temperature may cause it to change as climate shifts. These changes are likely to be complex because temperatures that occur during seed maturation and temperatures that occur post-dispersal interact to define germination timing. We used the model organism Arabidopsis thaliana to determine how flowering time (which defines seed...

Seed germination is a crucial stage in the life history of a species because it represents the pathway from adult to offspring, and it can affect the distribution and abundance of species in communities. In this study, we examined the effects of phylogenetic, life history and environmental factors on seed germination of 134 common species from an alpine/subalpine meadow on the eastern Tibetan P...

Giant foxtail (Setaria faberi) seeds differ in requirements for germination. Variable germinability arises during seed development under the influence of genotype, environment and parent plant. Giant foxtail seed germination has been shown to be regulated by independent asynchronous or dependent synchronous action of seed structures. To gain better insight into the process, germination was divi...

(How and why to measure the germination process?). In the last two centuries, papers have been published including measurements of the germination process. High diversity of mathematical expressions has made comparisons between papers and some times the interpretation of results difficult. Thus, in this paper is included a review about measurements of the germination process, with an analysis o...
