“…We are aware of UK records going back to the 1730s (Sparks and Carey 1995) and expect that, sooner or later, we might uncover some that are older. Certainly some very old records still exist for China (Hameed and Gong 1994) and Japan (Lauscher 1978). In a desire to co-ordinate British records and to examine the relationship between daily life and meteorological conditions, the Royal Meteorological Society commenced a phenology network in 1875.…”

This paper examines the mean flowering times of 11 plant species in the British Isles over a 58-year period, and the flowering times of a further 13 (and leafing time of an additional 1) for a reduced period of 20 years. Timings were compared to Central England temperatures and all 25 phenological events were significantly related (P<0.001 in all but 1 case) to temperature. These findings are discussed in relation to other published work. The conclusions drawn from this work are that timings of spring and summer species will get progressively earlier as the climate warms, but that the lower limit for a flowering date is probably best determined by examining species phenology at the southern limit of their distribution.

“…Fortunately there are some historical phenological observation series of full-grown plants in natural conditions that can be utilised for phenological modelling (e.g. Lauscher 1978, Lauscher and Lauscher 1981, Hunter and Lechowicz 1992, Kramer 1994, Fitter et al 1995, Sparks and Carey 1995, White 1995. Since the phenological data mostly consist of only one observation per year (one exception being the paper by Jeffree (1960), presenting the data by the British Royal Meteorological Society), they are vulnerable to observation errors, misprints and anomalies in the local microclimate of the observation site.…”

were constructed from data collected in Finland during the period 1896-1955. The resulting combined time series were examined with two aims in mind: first, to determine the phenological regularities between different species and, second, to detect patterns of spring advancement over a geographically large area. The results indicate that the geographical pattern of spring advancement is rather uniform from year to year, and between different species. Furthermore, the mechanisms regulating the timing of phenological events in different species seem to function in a similar way, suggesting an unanimous optimal response to climatic conditions.

“…For lilac the cold requirement is usually fulfilled by the end of November (SCH € U UEPP [31]). After that, lilac twigs flower after being exposed to warm water and a room temperature of [15][16][17][18] C (MOLISCH [24, p. 202]). In the temperate climate zone the timing of bud break and flowering mostly depends on passing a certain temperature threshold.…”

“…Developmental processes that respond to seasonal changes are the emergence of bud break, unfolding of leaves, onset of flowering and fruit ripening as well as leaf senescence. The evaluation of phenological dates provides valuable information about the average times of onset and the duration of different phenophases of characteristic species in a given area (ROSENKRANZ [29], SCHNELLE [30], LAUSCHER [17]). …”

Altitudinal Variation in Flowering Time of Lilac (Syringa vulgarisL.) in the Alps in Relation to Temperatures

The flowering time of lilac is a frequently used bioindicator for temperature driven developmental processes in spring time. In the present study the influence of altitude on the flowering dates of lilac was investigated for 24 sites in the Northern and Central Alps, and 10 sites in the Southern Alps. The onset of flowering dates in these areas of the Alps are closely related to the mean air temperatures in April. A temperature decrease by 1 C postpones the onset of flowering by 6.6 days. This results in a gradient of lilac flowering times of 4.2-4.6 days per 100 m in the Central Alps between 600 and 1500 m a.s.l. and a gradient of 3.7 days per 100 m a.s.l. in the Southern Alps between 90 and 1100 m a.s.l.Over the 20th century a deviation from the mean onset of flowering dates of about AE12 days was seen due to climatic fluctuations in the Northern and Central Alps. On the Southern rim of the Alps the thermal conditions are most favourable for the development of lilac and therefore, there are no remarkable time shifts to be seen.
