Fig. 3 The correlation analysis between lint yield and the dynamic characteristic values of sink dry matter accumulation and opening boll number Yield indicates lint yield. t1 and t2 are the start time and termination time of the fast accumulation period, respectively; Δt indicates the duration of the fast accumulation period; VT is the average accumulation rate during the fast accumulation period. K is the theoretical maximum dry matter accumulation or the theoretical maximum number of organs. OB is opening bolls; Sink indicates the sink organs. * and ** indicate significant relationship at the 0.05 and 0.01 level, respectively.
