RhNAP- or RhCKX6-silencing reduced dehydration tolerance in rose petal discs. Expression of RhNAP and RhCKX6 was silenced in petal discs by virus induced gene silencing (VIGS). Petal discs were dehydrated for 12 h and examined at intervals during 24 h of rehydration. A The phenotypes of the petal discs were recorded and photographed at different time points. The fresh weight (B) and recovery area (C) of the petal discs were determined. n = 5 ± standard deviation values are shown in (B) and (C); Student’s t-test, *P < 0.05, **P < 0.01. Dehyd, dehydration; Rehyd, rehydration
