BlütezeitÜberschneidungen

Blütezeitübersicht is a term used in botany and phenology to describe the timing and duration of flowering for a plant species, population, or region. It records when flowering begins, when it reaches peak abundance, and when flowering ends. The data typically include dates or day numbers and, in some cases, the rate of flowering.

Blütezeitübersicht is subject to variation between years, locations and cultivars. It is controlled by genetic factors and environmental cues such as photoperiod, temperature, chilling requirements, moisture, and altitude. Warmer springs generally advance onset; insufficient winter chilling or drought can delay or shorten the season.

Data sources include long-term field observations, herbarium specimens with flowering dates, dedicated phenology networks, citizen science platforms, and remote sensing for canopy flowering signals.

Uses include agriculture (timing of pollination and fruit set), horticulture (planning of displays and bloom timing), ecology and conservation (plant-pollinator synchrony, community dynamics), and climate-change monitoring (latitudinal/altitudinal shifts, phenological mismatch).

Examples include cherry blossoms in Japan; grapevine flowering in wine regions; alpine wildflowers with late-spring blooms.

Overall, the term is widely used in German-language literature and international phenology discussions.
