FIGURE 8 Effects of drought stress on the aboveground traits of
”Guoxin 02” and ”Ji 228”. (A) Representative images of the growth of
”Guoxin 02” and ”Ji 228” at 0d, 5d, 10d, and 15d after drought stress.
Statistical analysis of the (B) ratio of variable to maximum
fluorescence (F v/F m), (C) leaf area, (D) leaf water
potential, (E) steam diameter, (F) leaf water saturation deficit, (G)
plant height, (H) relative water content, (I) SPAD value, (J) stomatal
length, (K) stomatal width, (L) stomatal opening, and (M) stomatal
density. DT type, drought-tolerant type ”Guoxin 02”; DS type,
drought-sensitive type ”Ji 228”. CK, no-stress; DS, drought stress; C,
varieties; D, drought. Error bars represent standard errors of the
means. P >0.05, no significance (ns); P <0.01, highly
significant difference (**). Different lowercase letters in the figure
indicate significant differences among different varieties and
treatments at the same time point (P ≤ 0.05).
