Table 2.

Effects of different nitrogen sources on the FA distribution of cucumber plants after FA treatment.

Treatments Root (μg·g−1 FW) Stem (μg·g−1 FW) Leaf (μg·g−1 FW)
1AF 195 ± 9 c 273 ± 12 a 142 ± 6 b
5AF 206 ± 21 c 238 ± 14 b 174 ± 14 a
1NF 270 ± 13 b 205 ± 7 b 120 ± 10 c
5NF 306 ± 17 a 168 ± 12 bc 100 ±5 d

Notes: plants were treated with 60 ppm FA and FA content was detected at 7 h after FA treatment when wilt symptoms occurred in 1 mM NO3−-fed plants. 1AF, 5AF (FA-treated 1 mM or 5 mM NH4+-fed plants, respectively); and 1NF, 5NF (FA-treated 1 mM or 5 mM NO3−-fed plants, respectively). The data are the means ± SD of four replicates. Significant differences (LSD test, p < 0.05) of the same parts of the plants among treatments are indicated by different letters.
