Diel growth patterns of young soybean (Glycine max) leaflets are synchronous throughout different positions on a plant

“…However, corresponding with limited C availability at night, both area-based growth rate and mass-based growth rates were faster during the day than night (Models 1, 2 in Supplementary Data Sheets 2, 3). Based on model outputs, maximum relative growth rates could be seen during early morning hours, which is in accordance with diel leaf growth patterns known for Arabidopsis and other dicot species (Walter et al, 2009; Friedli and Walter, 2015). …”

“…In previous studies, the peak of relative leaf area growth rates of young, annual dicotyledonous plants has been observed in the night and/or early morning (Ainsworth et al 2005;Dornbusch et al 2014;Friedli and Walter 2015;Poiré et al 2010;Pantin et al 2011;Schurr et al 2000). Our results fit well to these previous findings and we observed the same pattern in our data (Fig.…”

“…6a), the relative diel leaf growth patterns previously observed by Friedli and Walter (2015). The rhythm observed by Friedli and Walter (2015) matched better with the rhythm of the area growth data measured by CT than the area growth data measured by digital imaging (Fig. 6a).…”

“…In the field, RGR mirrored the increasing temperature with an increase during the day and with overall lower growth rates at night compared to growth rates at day (Figure 1a ). In contrast, the observed RGR in the binary temperature regime displayed the reported pattern for soybean growth, where nocturnal RGR is high, reaching a maximum towards the end of the night/beginning of the day, whereas a minimal growth rate is observed in the mid‐afternoon (Figure 1b ; Friedli & Walter, 2015 ). In order to test whether the observed pattern from the field could be reproduced under controlled conditions, an experiment was performed in 2015 for which the diel temperature mimicked the temperatures experienced in the field (Figure S1 a–c).…”
