| Abstract: |
| The thermo-sensitive male-sterile line 1S of flax was studied with different planting density.The results indicated that the growth of thermo-sensitive male-sterile line in flax was affected by different planting density.With the increasing of planting density, the florescence and maturity was delayed, the increase of plant height was slowed in the same growth period, and the number of fruit and flowers per plant was decreased.However, pollen fertility was not obviously affected by planting density.We concluded that the flowering period and the number of flowers per plant could be changed by planting density, thereby, the adverse effects of the fertile instability were overcome to some extend in thermo-sensitive male-sterile flax. |
