Effect of drought-hardening on chlorophyll and multicolor fluorescence parameters in response to drought stress. PSII quantum Yield (QY_Lss) (a), open reaction centers (qP_Lss) (b), a ratio of fluorescence decline (Rfd_Lss) (c), and blue fluorescence (BF) (d) of the various drought-hardening and non-drought-hardening treatments. Data represented means ± SD. Different letters indicate a significant difference at LSD, p < 0.05. HCK represents HongHuaDaJinYuan seedlings with no drought-hardening; HT1 indicates 24 h drought-hardened seedlings of HongHuaDaJinYuan; HT2 indicates 48 h drought-hardened seedlings of HongHuaDaJinYuan; HT3 indicates 72 h drought-hardened seedlings of HongHuaDaJinYuan; YCK represents Yun Yan-100 seedlings with no drought-hardening; YT1 indicates 24 h drought-hardened seedlings of Yun Yan-100; YT2 indicates 48 h drought-hardened seedlings of Yun Yan-100; YT3 indicates 72 h drought-hardened seedlings of Yun Yan-100
