From: Extreme summer heat and drought lead to early fruit abortion in European beech
Differences of summer weather conditions and deviations of long-term mean summer soil matric potential between years with fruit abortion and years with fruiting success in European beech inside stands. Deviations from average summer conditions: (a) precipitation sums, (b) mean temperatures, summer soil matric potential in (c) 15 cm, (d) 30 cm, (e) 50 cm and (f) 80 cm soil depth. p values from two-sided t tests. Years with fruit abortion: BET: 2002, 2003, 2018; SCH: 2006, 2018; years with fruiting success: BET: 2004, 2011, 2014; SCH: 2011, 2016. BET Bettlachstock, SCH Schänis.
