Fig. 2

The changes of weight and growth curves of LE and JG apricot during fruit development stages. In a1, b1, c1, points and solid lines represent actual measured values, and the dotted line represent fit curves of equation. In a2, b2, c2, two different lines are fit curves of the first derivative of equations. Numbers under the x–axis indicate the days after full bloom. S1, first exponential growth stage; S2, slow–growth stage; S3, second exponential growth culminating in fruit ripening stage; S4, fruit ripening stage. Error bars indicate the standard deviation of ten biological replications. Label: ‘*’ means the significant differences at P < 0.05 by DMRT
