The shoot dry weights (SDW) of Zhengdan 958
(ZD958) and Jundan 20 (JD20) under IR-DS were only 74% and 61% of those of the same two
cultivars, respectively, under the controls in the absence of both exogenous ABA and fluridone (Flu),
89% and 73%, respectively, in the presence of ABA, and 67% and 65%, respectively, in the presence
of Flu. The leaf relative content (RWC) of ZD958 and JD20 treated with PEG alone had 90% and 87%
of the controls, 96% and 91% with both PEG and Flu, and 87% and 82% with both PEG and ABA
