用春小麦纯系种子进行了加硼及水处理的航天试验．结果表明，航天处理后种子发芽势提高１０％－１５％，发芽率提高２％－６％，Ｍ１代田间出苗率提高８．５％，与对照相比达到显著水平，水＋航天处理ＳＰ１代小区产量提高２６．１％；航天处理后放置不同时期的发芽试验结果基本一致，硼酸＋航天与水＋航天处理比未表现出抑制作用；航天处理ＳＰ２代的主要农艺性状的变异系数和突变频率及正向突变率都很高．
Pure spring germplasm with spring wheat was added boron and water aerospace trials. The results showed that germination potential of seeds increased by 10% -15% and germination rate increased by 2% -6% after aerospace treatment, and germination rate increased by 8.5% in M1 field, reaching significant level compared with the control The yield of plots increased by 26.1%. The results of germination tests after space treatment were basically the same in different periods, and no inhibition was found between boric acid + aerospace and water + aerospace treatments. The coefficient of variation and mutation frequency of main agronomic traits in aerobic treatment of SP2 generation And the positive mutation rate is high.
