Abstract
Embryo rescue techniques are the effective ways to overcome the fruit tree hybrid embryos early abortive.In order to find out basic methods of immature embryo culture into seedlings,two apricot varieties(cvs.‘Yellow River'and ‘Golden Sun')with different developmental stages of young embryo was used as materials.The influence of embryo age,the basic medium and plant growth regulator was studied on young embryo germination and seedling.The results showed that the genotype,embryo development index(PF),medium significantly affected young embryo germination and seedling.Different varieties along with the increase of PF value in the young embryo germination rate.PF value of‘Yellow River'apricot at0.92 had the highest germination rate,with 61.90%.PF value of‘Golden Sun''apricot at 0.95 had the highest germination rate,with 71.00%.The optimum medium for young embryo germination‘Yellow River'was MS+6-BA 1.0mg/L+0.1mg/L+IAA GA 2.0mg/L,germination rate was 55.67%.The optimum medium for young embryo germination'Golden Sun'was 1/2MS+6-BA 0.5mg/L+IAA 0.1mg/L,germination rate was 88.67%.The optimum transgenerational medium for‘Yellow River'was MS+6-BA0.2 mg/L+IAA 0.5 mg/L,seedling rate was 75.00%.The optimum transgenerational medium for‘Golden Sun'was MS+6-BA 0.25mg/L+IAA 0.1mg/L,seedling rate was 44.44%.Two apricot germ,The rooting rate of young shoots in 1/3 MS medium was higher than that in 1/2 MS medium.
