用0.2%浓度的秋水仙素溶液处理石刁柏萌芽种子48h,获得了较好的诱变结果。最后得到了四倍体。其诱变率为36.8%。对四倍体石刁柏进行了形态观察和染色体数的鉴定,其染色体数是n=20,2n=40,井初步分析了四倍体嫩茎的粗脂肪,粗蛋白,粗灰分,16种氨基酸及维生素C等营养成分,其含量均比二倍体高。 The germination seeds of Asparagus officinalis L. were treated with 0.2% colchicine solution for 48h, and the better mutagenesis results were obtained. Finally, the tetraploid. The mutation rate was 36.8%. The morphological observation and chromosome number identification of tetraploid Asparagus officinalis were carried out. The number of chromosomes was n = 20, 2n = 40, and the crude fat, crude protein, crude ash, Amino acids and vitamin C and other nutrients, its content higher than diploid.
