Correlation analysis between endogenous hormones levels and grain filling parameters.

Wmax Gmax Gave P
ZR 0.817 * 0.860 ** 0.864 ** 0.422
IAA 0.874 ** 0.963 ** 0.962 ** 0.608
ABA 0.855 ** 0.946 ** 0.944 ** 0.623
GA3 −0.832 * −0.884 ** −0.886 ** −0.464

ZR, zeatin riboside; IAA, indole-3-acetic acid; ABA, abscisic acid; GA3, gibberellin; Wmax, grain weight of reaching maximum grain filling rate; Gmax, maximum grain filling rate; Gave, average grain filling rate; P, active grain filling duration. Significant differences are shown by * and ** at the 0.05 and 0.01 probability levels (n = 8), respectively.
