Representative chlorophyll and multicolor fluorescence images. PSII quantum yield (QY_Lss) and qP_Lss (open reaction centers) and multicolor fluorescence images of blue fluorescence (BF) of the two tobacco varieties, HongHuaDaJinYuan (H) and Yun Yan-100 (Y) of various drought-hardening treatments along with control under drought stress. CK represents no drought-hardening; T1 indicates drought-hardening for 24 h; T2 indicates drought-hardening for 48 h; T3 indicates drought-hardening for 72 h
