Pollen fertility of D52S and NK58S by a MEJA/SHAM-spraying treatment.
| Photoperiod Condition |
D52S | NK58S | ||||
|---|---|---|---|---|---|---|
| Spraying | S/F Plant | Pollen Fertility (%) | Spraying | S/F Plant | Pollen Fertility (%) | |
| LD | Control | D52S-F | 21.54 ± 4.91 | Control | NK58S-S | 0.25 ± 0.01 |
| 0.5 mM SHAM | D52S-S-R | 8.63 ± 1.78 ** | 1 mM MEJA | NK58S-F-R | 19.01 ± 2.66 ** | |
| SD | Control | D52S-S | 0.54 ± 0.01 | Control | NK58S-F | 21.54 ± 6.11 |
| 1 mM MEJA | D52S-F-R | 64.07 ± 7.00 ** | 0.5 mM SHAM | NK58S-S-R | 0.19 ± 0.01 ** | |
Values are expressed as mean ± standard deviation, n = 120. ** Asterisks indicate significant differences of pollen fertility between spraying-induced reversed-fertility plants and those in the control group revealed by Student’s t-test (p < 0.01). LD, long-day cycle of 14 h-light and 10 h-dark; SD, short-day cycle of 10 h-light and 14 h-dark; S/F/R, sterile/fertile/fertility-reverse plants; MEJA, methyl jasmonate; SHAM, salicylhydroxamic acid.
