1., get flax bud that the pollen microspore is in the monokaryon middle and later periods, put into 2% liquor natrii hypochloritis sterilization 15 minutes, use aseptic water washing again 3 times, take out flower pesticide and put into the culture dish that fills sterile water, with the acupuncture method for releasing pollen grain is discharged in the sterile water, again by filtering centrifugal collection pollen;
2., adjust pollen density 5.0 * 10
2Individual/ml, be prepared into pollen suspension, be inoculated into flax pollen callus inducing culture HF
1In, induce pollen callus, be to cultivate under 2000LX, 8 hours/day the condition of light application time at 18-25 ℃, intensity of illumination;
3., when flax pollen callus length to about the 3-5mm, change flax pollen callus differential medium HF over to
2In, induce the differentiation of the green seedling of pollen, be to cultivate under 2000LX, 12 hours/day the condition of light application time at 18-25 ℃, intensity of illumination;
4., the plant that 3. step is obtained changes the green seedling rooting medium of flax pollen HF over to
3In, be that 2000LX, light application time are to cultivate under 15 hours/day the condition at 18-25 ℃, intensity of illumination.
