Minimum temperature differences between the meteorological screen and grass in radiative frost nightsDiferenças de temperatura mínima entre o abrigo meteorológico e a relva em noites com geadas
(2018-11-01)
A phenomenon called thermal inversion, in which there is the accumulation of colder and denser air in the layers closer to the soil, occurs in radiative frost nights, resulting in a temperature gradient with differences ...
Fire cues and germination of invasive and native grasses in the Cerrado
(Soc Botanica Brasil, 2020-01-01)
Fire-related cues may enhance seed recruitment in flammable ecosystems and differences in fire-germination responses of invasive vs. native species can drive the invasion process. We evaluated the effects of heat shock and ...
Influence of the types of grass of green roofs for the design of thermal comfort in buildings
(Polskie Towarzystwo Inzynierii Ekologicznej (PTIE), 2022-01-01)
The main objective of the research was to study the effect of the Stenotaphrum secundatum and Zoysia japonica grasses on the higher and lower environment temperature and lower relative humidity; the secondary objective was ...
How does fire affect germination of grasses in the Cerrado?
(2020-01-01)
Fire is a frequent disturbance in the Cerrado and is one of the major factors affecting vegetation structure and diversity. Fire events open gaps within the herbaceous layer and increase temperature fluctuation in the soil ...
Phytosanitary quality of Brachiaria brizantha 'BRS Piata' seeds in function of climate conditions
(Univ Federal Campina Grande, 2019-04-01)
Infected seeds are one of the main pathogen transmission vehicles, and they are responsible for significant losses in production fields; phytosanitary defense depends on the inoculum and climatic factors. Thus, in this ...
Grazing time and milk production of crossbred cows in a rotational area of Elephant grass and Tanzania grass
(2004-11-01)
This study was carried out in January of two consecutive years. The objective was to evaluate the grazing time, the grazing rate and the milk production of crossbred cows, managed in two rotational grazing areas, one with ...
Fire temperature effects on perennial grasses from northwestern Patagonian grasslands
(Springer Tokyo, 2015-01)
Post-fire recovery of perennial plants depends on their capacity to regrow from surviving meristems. Plants are adapted to a particular fire regime, which can be altered by human activities and climatic change. Therefore, ...
A plurality of causal mechanisms explains the persistence or transience of soil seed banks
(Academic Press Ltd - Elsevier Science Ltd, 2010-02)
Annual forbs form short-term persistent soil seed banks whereas perennial grasses form mostly transient ones in the central Monte desert. A conceptual framework predicts that annual forb seeds will have primary dormancy, ...
Germination of grasses and shrubs under various water stress and temperature conditionsGerminación de gramíneas y arbustos bajo varias condiciones de estrés hídrico y temperatura
(Acad Economic Studies, 2007-12)
Los efectos de varias combinaciones de potencial hídrico y temperatura se determinaron en la germinación de Atriplex lampa Gill. ex Moquin, Larrea divaricata Cav., Leymus erianthus (Phil.) Dubcovsky, Stipa neaei Nees ex ...
