Direct seeding reduces costs, but it is not promising for restoring tropical seasonal forests
(2018-06-01)
Direct seeding is a potential technique to restore forests; however, further studies are needed before its application on a large scale. We carried out a field experiment in a deforested area in southern Brazil to test the ...
Partitioning the relative contribution of one-phase and two-phase seed dispersal when evaluating seed dispersal effectiveness
(Wiley-Blackwell, 2015-02-01)
Seed dispersal effectiveness (SDE) is a conceptual framework that aims at quantifying the contribution of seed dispersal vectors to plant fitness. While it is well recognized that diplochorous dispersal systems, characterized ...
Optimising tetrazolium test procedures to evaluate the physiological potential of peanut seeds
(Ista-int Seed Testing Assoc, 2012-01-01)
The tetrazolium test stands out as an evaluation method in determining seed physiological potential due to the diversity of the information provided. Nonetheless, efficiency depends on following appropriate procedures, ...
Relationship Among Phenolic Contents, Seed Predation, and Physical Seed Traits in Mimosa bimucronata Plants
(Springer, 2009-12-01)
Phenolic contents were compared between Mimosa bimucronata seeds from infested and non-infested fruits to assess induced defense response. By measuring leg length of the bruchid beetle Acanthoscelides schrankiae, we verified ...
Key decision-making criteria for dormancy-breaking and ability to form seed banks of Cerrado native tree species
(Soc Botanica Brasil, 2020-10-01)
Ecological restoration by direct seeding in the Cerrado biome still lacks information about native species germination, the need for dormancy overcoming and seed bank formation. This study aims to verify the effects of ...
Reciprocal effect of parental lines on the physiological potential and seed composition of corn hybrid seeds
(2017-09-01)
Obtaining corn hybrid seeds (Zea mays L.) with high vigour depends on the parental lines and the direction of the cross, and this relates to seed desiccation tolerance and composition. This research studied reciprocal ...
Seed bank dynamics in tall-tussock grasslands along an altitudinal gradient
(Wiley Blackwell Publishing, Inc, 2003-02)
We studied the germinable soil seed bank of tall-tussock grasslands along an altitudinal gradient in the mountains of central Argentina. We selected 10 sampling plots at three altitudinal levels (1200 m, 1600 m and 2200 ...
Seed germination performances of Styrax species help understand their distribution in Cerrado areas in Brazil
(Inst Agronomico, 2013-01-01)
In this descriptive paper, we described germination responses of Styrax pohlii, S. camporum and S. ferrugineus seeds at 5, 10, 15, 20, 25, 30, 35, 40 and 45 degrees C. We also assessed the percentage germination (% G) of ...
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 ...
