白鶴芋體胚高效快繁體系的建立及多倍體誘導(dǎo)研究
[Abstract]:In this study, the inflorescence and root stem of Mojo' variety were used as experimental materials. The somatic embryogenesis and organogenesis were studied in the aspects of hormone type, hormone concentration and AgN03 concentration and nutrition level. Colchicine, ammosulfurin and fluralin were used to induce polyploidy of white crane taro, which provided references for polyploid breeding and breeding of new varieties of white crane taro. The main results were as follows: (1) the best formula for embryogenic callus induction was MS TDZ 5.0 mg L ~ (-1) NAA 0.2 mg L ~ (-1), and the induction rate was 64.97%. The best formula of rhizome embryogenic callus induction was MS 24-D 4 mg L -1 TDZ 0.5 mg L -1, the inducing rate was 87.440.The best formula of rhizome embryogenic callus induction was MS 2N 4-D 1mg L -1 TDZ 0.5 mg L -1, and the induction rate was 92.33%. Rhizome was the best explant for embryogenic callus induction. (2) the callus proliferation and growth state were the best when the callus was treated with 2 mg L ~ (-1) AgNO3. (3) the best hormone formula for embryoid induction was MS 6-BA 1 mg L-1 TDZ 0.2 mg L -1 NAA 0.2 mg L -1, the best somatic embryo germination nutrition and hormone level was 1/2MS TDZ 0.1 mg L -1 IBA 1.0 mg L -1, and the germination rate was 70.54%. The optimum formula was MS 6-BA 0.8 mg L -1 IBA 0.2 mg L -1 and regeneration rate 89.34 4. The best rooting formula was MS AC 1 g L-1 NAA0.2 mg L -1. (4) the somatic embryogenesis process was similar to that of monocotyledonous embryos, and was mainly divided into the following stages: embryogenic cells, globular embryos, elliptical embryos, pellet embryos, and peltate embryos. Cotyledonous embryo, mature somatic embryo. (5) the chromosome slice technique was optimized. The chromosome was prepared with 0.002 mol L-18-hydroxyquinoline or 0.07 mmol L-1 actinomycin for 4 h at 8: 45-9: 15 in the morning. The chromosome number of Mojo' was 2nnnt2xan30, which was diploid. (6) the somatic embryos and buds of Mojo' were used as experimental materials to study the induction of tetraploid of somatic embryos and buds with different concentrations of colchicine, amsulfurin and trifluridine solution. The best method of tetraploid induction was 0.08% colchicine for 15 days. The best method for inducing tetraploid was 100 mg L-1 trifluridine for 5 days. The induction rate of young bud was higher than that of somatic embryo, and the polyploid induction of young bud was easier than that of somatic embryo. (7) the tetraploid was identified in morphology, chromosome number and stomata. It was found that tetraploid plants grew stronger than diploid plants, their leaves were thicker and thicker, leaf color was dark green, leaf shape index was smaller, leaf shape was more symmetrical, and plant type was compact. The chromosome number of diploid and tetraploid was 2nnm2xc30 and 2nm4xm60respectively, and the number of chromosome doubled. The stomata of tetraploid were larger than that of diploid, and the number of stomata in the same area was decreased.
