Figure 1. Effects of cinnamic acid (CA) on the plant biomass of non-grafted (NG) and rootstock grafted (RG) cucumber seedlings.

Figure 1

Samples were collected at 7 days after exposed to 0 mM (white bars) and 0.5 mM CA (dark bars). Data are means ± standard error of n = 9. Statistical different analysis was conducted between control and cinnamic acid treatment based on the least significant difference test (LSD). Bars sharing the same letters are not significantly different at the 5% level. (A–C) Fresh weight, dry weight and ratio of fresh and dry weight in shoot; (D–F) fresh weight, dry weight and ratio of fresh and dry weight in root.
