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; V_T 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.
