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 ...
Germination of native and exotic seeds dispersed by wild black-and-gold howler monkeys (Alouatta caraya): assessing deinhibition and scarification effects
(Springer Tokyo, 2020-01)
Fruit ingestion by frugivores and the subsequent passage of seeds through their digestive tract can influence seed germination patterns. The removal of germination inhibitors contained in the fruit pulp (deinhibition ...
Non-redundancy in seed dispersal and germination by native and introduced frugivorous birds: implications of invasive bird impact on native plant communities
(Springer, 2018-12)
Seed dispersal by vertebrate animals is important for the establishment of many fleshy-fruited plant species. Different frugivorous species can provide different seed dispersal services according to their specific dietary ...
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), ...
Physiological Fitness Cost Associated with Glyphosate Resistance in Echinochloa colona: Seed Germination Ecology
(Malaysian Society of Plant Physiology, 2019-12)
The expression of fitness cost associated with herbicide resistance in weeds is not universal and may vary during different life stages. Hence, an analysis of the fitness cost of a glyphosate-resistant Echinochloa colona ...
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, ...
Effects of long-term seed storage on germination of 13 cactus species from central Argentina
(Academic Press Ltd - Elsevier Science Ltd, 2021-02)
Understanding the effects of long-term seed storage on germination is important to elucidate both soil seed bank dynamics and capacity of seeds to be preserved in ex situ conservation programs. We collected seeds 13 cactus ...
Germination response of Lithraea molleoides seeds is similar after passage through the guts of several avian and a single mammalian disperser
(Canadian Science Publishing, 2018-04-05)
Seed dispersal by vertebrate frugivores plays an important role in plant population dynamics and community structure. The gut treatment may modify the germination response of seeds; often the specific effects of seed ...
