Fig. 1

Variation of developing acorns at two sites. a, Length of acorns in July, August, September, and October growing at the two contrasting-P sites. b, Width of acorns in July, August, September, and October growing at the two contrasting-P sites. c, Dry weight of single acorn in July, August, September, and October growing at the two contrasting-P sites. Vertical bars indicate standard error of each mean (in July, n = 6 at P-rich and P-deficient sites; in August, September and October, n = 8 at P-rich and P-deficient sites). Different lowercase letters above the columns at P-rich site or P-deficient site means that length, width and dry weight were significantly different in acorns at different developmental stages under a particular soil condition (P-rich and P-deficient sites), respectively. There were no significant differences (p = 0.05) in acorns at P-rich and P-deficient sites at a particular developmental stage
