El género Coursetia se distribuye ... -
Germination and emergence of corn (Zea mays, L) as a function of soil physical parameters
(Oregon State University, 1988-12)Rates of germination and emergence of corn were measured as influenced by soil physical parameters using blotter paper and a sandy loam soil as growth media. The corn seeds used were a hybrid of Funk's (DJ7xLH93). Experimental ... -
Germination requirements of two sheep-preferred grasses (Hordeum comosum and Koeleria vurilochensis var. patagonica) from semiarid Patagonian steppes
(Elsevier, 2012-03)Grazing by domestic exotic herbivores on native vegetation in Patagonian steppes has led to the deterioration of forage resources, where grasses are replaced by shrubs, and preferred grasses by non-preferred ones. Therefore, ... -
Influencia de las condiciones de incubación sobre la germinación de semillas de diferentes individuos de Pterogyne nitens = Influence of incubation conditions on germination of seeds of different individuals of Pterogyne nitens Tul ex Benth

El objetivo del presente ... -
Jatropha curcas L. and J. macrocarpa Griseb: seed morphology, viability, dormancy, germination and growth of seedlings
(Scientific Research, 2018-08)To achieve a good production of a crop, it is essential to know the ability of the species to successfully complete two critical stages in the life cycle such as germination and seedling establishment. In this paper we ... -
Modeling seed dormancy release and germination for predicting Avena fatua L. field emergence: A genetic algorithm approach
(2014-01-24)Avena fatua is a cosmopolite weed species which produces severe yield losses in small-grain production systems in temperate and semiarid climates. In the semiarid region of Argentina, A. fatua field emergence patterns show ... -
Overcoming seed dormancy of junglerice (Echinochloa colona)
(Universidad de Concepción (Chile), 2022-08)Junglerice (Echinochloa colona L. Link) seed dormancy can persist 8 months after harvest and, once overcome, seeds can germinate over a long period of time. Light or high temperatures could overcome seed dormancy, while ... -
Physiological and molecular mechanisms underlying the integration of light and temperature cues in Arabidopsis thaliana seeds
(Wiley, 2017-09-23)The relief of dormancy and the promotion of seed germination are of extreme importance for a successful seedling establishment. Although alternating temperatures and light are signals promoting the relief of seed dormancy, ... -
Promotion of Immature Seed Germination in Jacaranda mimosifolia
(American Society for Horticultural Science, 2005-08)In vitro germination of immature seeds of Jacaranda mimosifolia treated with gibberellic acid (GA3) was studied. Immature seeds were collected monthly after crossings and sown on Murashige and Skoog (1962) medium with 3.0% ... -
Pureza física y germinación de cariopses de Chloris gayana Kunth y Panicum coloratum L. cosechados de plantas cultivadas en un suelo alcalino-sódico
(2018-04)El objetivo del estudio fue evaluar la pureza física, el porcentaje de germinación (G), la velocidad de germinación (VG) de cariopses de Chloris gayana cv. Finecut (Cg) y Panicum coloratum cv. Klein Verde (Pc) recolectados ... -
Ranges of Vigor Based on the Electrical Conductivity Test in Dehulled Sunflower Seeds
(Academic Journals, 2015)Electrical Conductivity (EC) is a promising vigor test since it produces fast laboratory results. In sunflower, the leakage of electrolytes from the pericarp may interfere with exudates from embryo tissues. The aims of ... -
Seed responses to temperature indicate different germination strategies among Festuca pallescens populations from semi-arid environments in North Patagonia
(Elsevier, 2019-04)Seed germination is one of the earliest phenotypes expressed by plants, and the accuracy to germinate in the correct time and place is essential for plant population fitness. Cues that regulate germination have been ... -
Seed weight and trade-offs: an experiment in false rhodes grasses under different aridity conditions
(MDPI, 2022)The false Rhodes grasses [Leptochloa crinita (Lag.) P.M. Peterson and N.W. Snow and Leptochloa pluriflora (E. Fourn.) P.M. Peterson and N.W. Snow] are considered valuable native forage resources for arid and semiarid ... -
Stratification temperature affects the In Vitro germination of immature Prunus embryos
(ISHS, 2004)The rapid multiplication of clonal plants is desirable to shorten crossing programs in fruit tree breeding. In vitro stratification and germination allowed us to shorten the time and to improve the germination rates by ... -
The Effects of Priming and Ageing on Seed Vigour in Tomato
(Oxford University Press, 1989-05)A comparison was made of the effects of seed priming or ageing treatments on the performance of tomato (Lycopersicon esculentum Mill. cv. UC204C) seeds according to a number of indices of seed vigour. A single lot of tomato ... -
The roles of light and pericarp on seed dormancy and germination in feral Raphanus sativus (Brassicaceae)
(Wiley, 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 ... -
Thermal buffering capacity of the germination phenotype across the environmental envelope of the Cactaceae
(Wiley, 2017-06-28)Recruitment from seeds is among the most vulnerable stage for plants as global temperatures change. While germination is the means by which the vast majority of the world's flora regenerate naturally, a framework for ... -
