Variation in the start of the grass pollen season at selected sites in the united kingdom 1987–1992

Abstract

(1994) Variation in the start of the grass pollen season at selected sites in the united kingdom 1987-1992

An examination of the main characteristics of the pollen seasons in Budapest, Hungary (1991–1996)

“…precipitation had no effect on the start of grass pollination, but higher pre-seasonal temperature promoted it. In Great Britain (Emberlin et al 1994) precipitation in the 2 months preceding pollination seems to delay the start. So, season start is limited in dry, hot areas by soil humidity, but in rainy, Atlantic climate areas by temperature.…”

Flowering Phenology of Selected Linden (TiliaL.) Taxa in Relation to Pollen Seasons

“…Investigation of the variability of phenological phases and pollen seasons is one of the indispensable elements in the development of calendars of flowering and pollen release in melliferous plants. Plant pollen seasons are regarded as indicators of variation in flowering phenology, plant ecology, and climate change (Emberlin et al, 1994(Emberlin et al, , 2002Menzel et al, 2006). Many authors show that the temperature in the period preceding flowering has a significant effect on the beginning of flowering and pollen release in plants (Primack et al, 2004;Juknys et al, 2011Juknys et al, , 2012Massetti, Petralli, & Orlandini, 2014).…”

Poaceae pollen in the atmosphere of Zagreb (Croatia), 2002 – 2005

“…Therefore it is important to monitor airborne pollen concentrations in city agglomerations. In recent years, a number of publications have highlighted differences or similarities that exist with pollen in the atmosphere at various locations (Green et al 2004;Emberlin et al 1994;Galan et al 1995).…”
