The reseach on activity changes of SOD, POD and CAT during the somatic embryogenesis of Y35 showed:(1) The activty of SOD was from 52.98 to 133.20 U·g-1·h-1, and remained a rising trend after early single embryo forming, this revealed that SOD might be positively correlated to the differentiation of embryogenic cell and the development of somatic embryo.(2) The activty of POD was from 0.05 to 0.50 U·mg-1·min-1, ascended firstly and desceded later, and was highest in embryogenic callus and lowest in late single embryo , this revealed that POD might be positively correlated to the division and differentiation of proembryo mass, while negatively correlated to the development of PEMⅢto late single embryo.(3) The activty of CAT was from 0.86 to 2.81 U·mg-1·min-1, showed an up-down-up trend, reaching to the highest peak at the time of early embryo formating and decreasing to the lowest at the time of early cotyledonary embryo formating, this revealed that CAT might be positively correlated to the development of early single embryo, while negatively correlated to the formation of middle single embryo and early cotyledonary embryo.The changes in activty of SOD, POD and CAT indicated these three antioxidant enzymes coregulated the differentiation and development of embryogenic cells during Larix somatic embryogenesis.4.

The nursery water was the best, when microencapsulated diets of "OK" and rotifera were blended at the percentage of 80% and 20%, the nursery water quality was the best during the rearing period, the highest concentration of NH3-Nt (NH3-Nm) was 1.025mg/L (0.0836mg/L),and the highest concentration of NO2-- N was 0.0236mg/L. When larvae emerged, the concentration of COD was 1.526mg/L, Puyrrop Hta was 1000 Entries/ml, and the metamorphic rates of all periods exceeded symmetrically 97%, and the survival rates also higher than the control group fed pure crude diets.

Our results showed that the most appropriate rib's level for applying force was below the apex of scoliotic spine. From this appropriate level, the stress delivered to its conjunctive vertebra was the highest, as 1.3~1.8 times compared with others. Furthermore, the correction of Cobb's angle was also the highest, achieved 15%. The ML force was dominant in alteration of Cobb's angle, whereas the AP force was dominant in alteration of axial vertebral rotation. In addition, initial vertebral rotation influenced neither correction nor stress.
