对中药黄芩的普通与航天种子进行了下列实验：（１）种子萌发对比实验；（２）在同一条件下的栽培实验；（３）遗传物质－－染色体形态的对比实验。结果表明：航天种子与普通黄芩种子对比，根长、根粗、株高都明显增加，染色体类型也发生了畸变，出现了染色体裂片、染色体桥、落后染色体、先行染色体。 The following experiments were conducted on common and aerospace seeds of Scutellaria baicalensis Georgi: (1) comparative experiments on seed germination; (2) cultivation experiments under the same conditions; and (3) comparative experiments on genetic material-chromosome morphology. The results showed that compared with the seeds of Scutellaria baicalensis, the root length, root diameter and plant height were significantly increased, the chromosome types were also distorted, and there were chromosomes, chromosome bridges, backward chromosomes and prechromosomes.
