Figure S1. The branch number of the tassels of the individual plants of maize
lines under different photoperiods. Each datum was the mean ± SD from
more than ten individual plants. *: the statistically significant difference at p <
0.05.
Figure S2. The silking score of maize lines under different photoperiods. The
methods for scoring were described in detail in METHODS.
Figure S3. The seed setting scoring of maize lines under different photoperiods. The
methods for scoring were described in detail in METHODS.
Figure S4. The plant height of maize lines under different photoperiods. Each datum
was the mean ± SD from more than ten individual plants. *: the statistically significant
difference at p < 0.05.
Figure S5. The length of the internodes of maize lines under different photoperiods.
Each datum was the mean ±SD from more than ten individual plants. *: the statistically
significant difference at p < 0.05.
Figure S6. The stem girth of maize lines under different photoperiods. Each datum was the
mean ± SD from more than ten individual plants. *: the statistically significant difference at
p < 0.05.
Figure S7. The leaf number of individual plants maize lines under different
photoperiods. Each datum was the mean ± SD from more than ten individual
plants. *: the statistically significant difference at p < 0.05.
Figure S8. The content of chlorophyll a in leaves of maize lines under different
photoperiods. Each datum was the mean ± SD from five individual plants. *: the
statistically significant difference at p < 0.05.
Figure S9 The stomatal density of leaves of maize lines under different photoperiods. The stomata
were counted from areas away from the main vein of the back of the freshly collected leaves. Each
datum was the mean ± SD from more than ten individual plants. *: the statistically significant
difference at p < 0.05.
Figure S10. The stomatal behavior of leaves of maize lines at V3 (A) and V9 (B) under different
photoperiods. The stomata were observed by scanning electron microscope from the leaf surface
tissue away from the main vein of the back of the leaves.
Figure S11. The pollen activity of maize lines under different photoperiods. The
methods for scoring were described in detail in METHODS.
Figure S12.The percentage of senescent leaves of individual plants of maize lines under different photoperiods. Each datum
was the mean ± SD from more than ten individual plants. Leaf senescence of plants was examined 91 d after planting. *:
the statistically significant difference at p < 0.05.
