Seed mass, seed number and evolutionary trade off across geographic distribution: do they explain invasiveness in Eschscholzia californica, central Chile?
(Taylor & Francis, 2017)
Background: Seed mass is a life history trait that is related to invasiveness. Under limiting conditions, a trade-off is observed whereby an increase in seed mass occurs at the expense of seed numbers; if the above trade-off ...

Comparison of methods to estimate soil seed banks: The role of seed size and mass
(Akadémiai Kiadó, 2012-12-21)
There are two main methods for estimating seed density and species composition of soil seed banks: manual seed extraction and seedling emergence. These methods were used to determine and compare seed density and species ...
Variation of seed mass and its effects on germination in Polylepis australis: Implications for seed collection
(Springer, 2007-03)
South American Polylepis mountain forests are recognised as being one of the most endangered forest ecosystems in the world. Reforestation measures have been strongly recommended but may be hampered due to the very low ...
Adequacy of the electrical conductivity test on Libidibia ferrea seeds (Mart. Ex Tul.) L. P. Queiroz var. ferrea classified with different masses
(2022-01-01)
This study aimed to adapt the methodology of the electrical conductivity test to detect differences in vigor between seeds of Libidibia ferrea of different masses. The seeds were classified according to their individual ...

Physiological maturity of Cnidosculus quercifolius Pax & K. Hoffm. seeds
(2008-03-01)
Cnidosculus quercifolius (Euphorbiaceae) is an important tree species native from the semi-arid region of the northeastern Brazil. Physiological maturity of seeds was studied in order to establish indices to determine the ...

Bottom-up and top-down effects in a pre-dispersal seed predation system: are non-predated seeds damaged?
(Elsevier Gmbh, Urban & Fischer Verlag, 2010-01-01)
Seed predators that severely affect seed germination rates are well known for many plant species. Here, we hypothesised that due to differences in resource allocation within fruits, seed predation can negatively affect ...
Seed mass and germination in Asteraceae species of Argentina
(International Seed Testing Association, 2009-07)
The effects of seed mass variation on germination percentage, mean time to germinate and light requirements for germination in seven Asteraceae species of Argentina were studied. Germination, mean time to germinate and ...
