Fig. 4From: Decoupling photo- and thermoperiod by projected climate change perturbs bud development, dormancy establishment and vernalization in the model tree PopulusBud development under short photoperiod at different temperatures. a Terminal buds at the indicated temperatures (at week 4). b Average lengths (vertical numbers) and widths (horizontal numbers) of terminal buds and axillary buds at the indicated temperature conditions (at week 6). Predormancy low temperature (12/12 °C) promoted anthocyanin production in both terminal and axillary buds, while buds at high temperature (24/24 °C) remained green. The relative color differences are indicated in the schemes. (values are means ± SE, n = 5 per data point)Back to article page
