Self-seed production by CO2 gas treatment in self-incompatible cabbage
- 143 Downloads
An adequate number of self-seeds was obtained in self-incompatible cabbage (Brassica oleracea L. var. capitata) when CO2 gas was supplied to flowers after self-pollination. A strain, which set 0.2 self-seeds per flower in the ambient air condition, set over 10 self-seeds per flower when treated with 3.6–5.9% CO2 for 5 h. In a strain with weaker self-incompatibility, a 4 h treatment with 1.4% CO2 was still effective.
Seed set in bud-pollination was also enhanced by applying CO2. This method is so simple that it may be used for practical self-seed production in Brassica vegetables.
