Evaluation of Walnut Tree Flowering and Frost Occurrence Probability During 1961-2012

Original language description

Strength and direction of the potential effect of climate change on walnuts is regionally specificn(Gauthier and Jacobs, 2011) as climate change will probably affect the spatial distribution of thenwalnut. This paper evaluated the long-term phenological series (1961–2012) of the beginningnof flowering, end of flowering and duration of flowering in walnut tree (Juglans regia) at twonphenological stations located in different geographical locations of the Czech Republic but in thensame climatic conditions (warm region). Phenological stages were analyzed in relation to growingndegree days and to spring frosts occurrence. Onset of the beginning and end of flowering occurrednearlier at Velké Pavlovice station (-2.1 and -1.3 days), and conversely occurred later at Doksanynstation (+1.8 and +1.0). Period of flowering shortened at Doksany station (-0.8 day) and prolongednat Velké Pavlovice station (+1.2 day). The occurrence of days with minimum air temperature < 0 °Cnduring walnut tree flowering was more frequent at Doksany station (in total, 29 days) with absolutenminimum value -5.5 °C. At Velké Pavlovice station 5 days with minimum air temperature belown0 °C were found during examined period with absolute minimum value -3.8 °C. The negative trendnin number of frost days occurrence during flowering period was found at both stations. Pearsonncorrelation coefficient between phenophase onset (and flowering period) and sums of growing degreendays was stronger at Velké Pavlovice station, and the highest value was between period of floweringnand temperature sums (0.782). The results confirmed our hypothesis of changes in phenophasenonsets and duration of flowering including spring frosts occurrence according to west-east gradientn(maritime climate-continental climate).
