Embodiment 1
[0017] When the cabbage self-incompatibility line material enters the initial flowering stage, spray 2 μg / ml carbonic anhydrase solution on the flowers that have just emerged from the stigma at 9:00 to 10:00 in the morning until fog droplets can be seen on the stigma. Spray once every 1 day, and stop spraying when 90% of the flowers on the plant are in bloom. The average pod setting rate of self-incompatible cabbage lines under this treatment can reach 39.8%, the average number of seeds per pod is 5, and the self-compatibility index increases from 0.08 to 1.99. The seeds are fuller.
Embodiment 2
[0019] When the cabbage self-incompatibility line material enters the initial flowering period, spray 8 μg / ml carbonic anhydrase solution on the flowers that have just emerged from the stigma at 9:30 to 10:30 in the morning, until fog droplets can be seen on the stigma, Spray once every 1 day, and stop spraying when 90% of the flowers on the plant are in bloom. The average pod setting rate of the cabbage self-incompatibility line under this treatment can reach 52.5%, the average number of seeds per pod is 7, and the self-compatibility index increases from 0.08 to 3.68. The seeds are fuller.
Embodiment 3
[0021] When the cabbage self-incompatibility line material enters the initial flowering period, spray 4 μg / ml carbonic anhydrase solution on the flowers that have just emerged from the stigma at 9:00 to 10:00 in the morning, until the stigma can be seen. Spray once every 1 day, and stop spraying when 90% of the flowers on the plant are in bloom. The average pod setting rate of self-incompatible lines of cabbage under this treatment can reach 78.4%, the average number of seeds per pod is 4, and the self-compatibility index increases from 0.31 to 3.12. The seeds are fuller.
