Abstract
Effects of different concentrations of 6-BA on ovule abortion and embryo culture of Thompson seedless grape were researched.The results indicated that when treated by different concentrations of 6-BA before two weeks blossom and abortion,it would be delayed more than 5 days.Germination rate of embryo of 45 days after flowers treated by 6-BA was supreme,more than 6.9%,was 1.7 times of CK.It was said than 6-BA could delay the abortion,extended the selection of female parent,improved the breeding efficiency of seedless grape.
