以大兴安岭种源樟子松种子为对照,对引进的9个盐松种源种子的表型性状和发芽特性进行了研究,结果表明:各种源种子净度高,含水量适中,适合干藏法贮藏;不同种源之间种子长、宽、厚、厚宽比、千粒质量、发芽率、发芽指数差异显著,而长宽比、发芽势和平均发芽时间差异不显著;四唑染色测种子的生活力结果与对比发芽试验的结果很接近,说明用四唑染色方法能较准确地测定盐松种子的发芽能力.对比引进盐松和国内樟子松种子发现,引进盐松种子在质量、体积和发芽能力上均高于国内樟子松种子,但形状差异不大.相关分析表明,引进种子各性状之间多数存在显著正相关关系.
以大興安嶺種源樟子鬆種子為對照,對引進的9箇鹽鬆種源種子的錶型性狀和髮芽特性進行瞭研究,結果錶明:各種源種子淨度高,含水量適中,適閤榦藏法貯藏;不同種源之間種子長、寬、厚、厚寬比、韆粒質量、髮芽率、髮芽指數差異顯著,而長寬比、髮芽勢和平均髮芽時間差異不顯著;四唑染色測種子的生活力結果與對比髮芽試驗的結果很接近,說明用四唑染色方法能較準確地測定鹽鬆種子的髮芽能力.對比引進鹽鬆和國內樟子鬆種子髮現,引進鹽鬆種子在質量、體積和髮芽能力上均高于國內樟子鬆種子,但形狀差異不大.相關分析錶明,引進種子各性狀之間多數存在顯著正相關關繫.

An experiment was conducted to study the phenotypic traits and germination characters of Pinus sylvestris ssp. kulen-densis seeds from nine provenances introduced from abroad by comparing with P. sylvestris ssp. mongolia seeds from Dax-ing' an Mountains. Results showed that the seeds from all the provenances had a high purity and a moderate water content,which was suitable for dry preservation. There were significant differences in seed length, width, thickness, thickness/width, 1 000-seed weight, germination percentage, and germination index among the provenances, but unobvious differ-ences in length/width, germination energy and average gemination time. The seed viability tested by TTC was close to the germination rate under controlled germination condition, indicating that it is reliable to apply the TTC dyeing method to germination potential test of seeds. Comparison between the seeds of two domestic tree species indicated that P. sylvestris ssp. kulendensis seeds were superior in mass, volume and germination potential, and similar in shape. Significant positive correlations were observed between most traits of the introduced seeds by correlation analysis.
