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, ...
The roles of light and pericarp on seed dormancy and germination in feral Raphanus sativus (Brassicaceae)
(Wiley Blackwell Publishing, Inc, 2019-08-19)
The timing of seed germination may determine the success of a weed species in an agroecosystem, and its expression is modulated by environmental conditions, but also by seed physiology and anatomy. The aims of this study ...
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 ...
Effect of light on seed germination of succulent species from the southern Chihuahuan Desert: comparing germinability and relative light germination
(Professional Association for Cactus Development, 2010)
Thermal requirements and germination niche breadth of Polygonum ferrugineum Wedd. from southeastern Brazil
(Cambridge University Press, 2021-05)
Temperature may regulate seed dormancy and germination and determine the geographical distribution of species. The present study investigated the thermal limits for seed germination of Polygonum ferrugineum (Polygonaceae), ...
Distinct germination responses may contribute to the distribution pattern of two Moquiniastrum species in different phytophysiognomies from the Brazilian savanna
(Elsevier B.V., 2016-08-01)
Understanding how germination traits can influence the distribution pattern of adult plants is still an important issue for seed ecologists and biologists. Here, we evaluated if seed germination responses to abiotic factors ...
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 ...
Dormancy and germination in three Acacia (Fabaceae) species from central Argentina
(Cambridge University Press, 2007-02)
We studied dormancy and germination requirements of seeds of Acacia aroma, A. caven and A. furcatispina from a semi-arid region of central Argentina. Imbibition experiments were performed to determine the rate of water ...
