Figure 1. The differences in the average air-temperature and
daylength between the EARLY and LATE rice-cultivation season.
(a ) Patterns of 10-year average daily air-temperature and
daylength variation in the EARLY (ES) and LATE (LS) rice-cultivation
seasons, respectively. Grey lines represent the air-temperature, and
black lines for daylength. (b ) Air-temperature differences
between the two rice-cultivation seasons at different rice growth
stages. White bars represent the early rice-cultivation season, and grey
bars for the late season. (c ) Daylength differences between the
two rice-cultivation seasons at different rice growth stages. White bars
represent the early rice-cultivation season, and black bars for the late
season. S, seedling; T, tillering; F, flowering; R, ripening. ***,p <0.001. Error bar, standard deviation.
Figure 2. Plant height of weedy rice populations at different
stages in the EARLY (-E) and LATE (-L) rice-cultivation seasons. Bar
plots show the plant height in CDE/L (a ), HJE/L (b )
and DCE/L (c ) population pairs at different stages,
respectively. *, p <0.05, ***, p <0.001.
Figure 3. Number of tillers per plant of weedy rice populations
at different stages in the EARLY (-E) and LATE (-L) rice-cultivation
seasons. Bar plots show the number of tillers per plant in CDE/L
(a ), HJE/L (b ) and DCE/L (c ) population pairs
at different stages, respectively. *, p <0.05, **,p <0.01, ***, p <0.001.
Figure 4. The flowering time patterns of weedy rice populations
in the EARLY rice-cultivation season. Flowering time patterns within
population pair are showed in (a) CDE/L, (b) HJE/L and (c) DCE/L,
respectively. Horizontal axes represent the date of flowering, indicated
by days after germination (DAG), and vertical axes represent the
proportion of flowering plants. Curves of weedy rice populations belong
to the same pair are plotted together to show the disjunction in
flowering time between the early- and late-season weedy rice
populations. Grey curves indicate the early-season weedy rice
populations, and black curves indicate the late-season weedy rice
populations.
Figure 5. Flowering time of weedy rice populations in the EARLY
(-E) and LATE (-L) rice-cultivation at different stages. Bar plots show
the flowering time when the proportion of flowering plants is determined
as 1%, 30%, 50% and 80% in (a) CDE/L, (b) HJE/L and (c) DCE/L
population pairs, respectively. *, p <0.05, **,p <0.01, ***, p <0.001.
Figure 6. Reproductive traits of the early- and late-season
weedy rice populations planting in the EARLY (-E) and LATE (-L)
rice-cultivation seasons. (a ) Grain per plant; (b )
Seed setting ratio; (c ) 100-seeds weight. *,p <0.05, **, p <0.01, ***,p <0.001. CD, Chi Dou; HJ, He Jia; DC, Dong Cun. E/L-E,
the early-/late-season populations planting in the EARLY
rice-cultivation season; E/L-L, the early-/late-season populations
planting in the LATE rice-cultivation season.
Figure 7. The model of local adaptation in weedy rice
associated with ambient temperature and daylength. WRE, the weedy rice
collected from the EARLY rice-cultivation seasons. WRL, the weedy rice
collected from the LATE rice-cultivation seasons.
