Effects different concentrations of 2,3-butanedione on the wolfberry fruit decay.

Concentrations (μL/L)	Decay incidence (%)	Disease index
0	100.00 ± 0.00a	49.63 ± 1.96a
20	92.59 ± 3.70b	22.50 ± 1.44b
40	48.15 ± 3.71c	7.83 ± 1.17c
60	0.00 ± 0.00d	0.00 ± 0.00d
80	0.00 ± 0.00d	0.00 ± 0.00d
100	0.00 ± 0.00d	0.00 ± 0.00d

Each value is the mean of three replicates ± standard error. Values in a column followed by a different letter are significantly different according to Duncan’s multiple range test at p < 0.05 level.
