以杉木种子园大龄母树为研究对象，对其进行截杆试验，对比分析截杆与未截杆处理对母树球果产量、球果大小、种子产量、种子质量以及种子发芽能力的影响。结果表明，截杆处理对大部分无性系母树种子产量、种子质量以及种子发芽能力均具有显著的促进作用。截杆处理对球果产量指标影响不显著，但截杆后球果鲜重和干重的综合增益值均在60％以上；单株种子重、出籽率、种子千粒重和优良度的综合增益值分别为104．23％、33．90％、17．08％和82．72％；种子发芽率、发芽势和发芽指数的综合增益值分别为130．32％、134．41％、133．28％。说明截杆处理可提高母树种子产量和质量，且可显著提升种子的发芽能力，提高种子发芽率和整齐度，缩短种子发芽时间。

Taking elder seed trees in Cunninghamia lanceolata orchard as the research object , a trunk-cutting ex-periment was carried out , and the influences of trunk-cutting and non-trunk-cutting treatment on cone yield , cone size , seed yield , seed quality , and seed germinating ability were analyzed .The results showed that trunk-cutting treatment has significant promoting effect on seed yield , seed quality , and seed germinating ability for most of fam-ilies.There were no significant effect on cone yield indexes after trunk-cutting treatment , but the GMG ( Group Merit Gain) of cone fresh weigh and dry weigh per plant was both above 60%.The GMG of seed weigh per plant , seed-production ratio , 1 000-grain weigh and fine degrees were 104.23 %, 33.90 %, 17.08 % and 82.72 %respectively .The GMG of seed germination rate , germination energy and germination index were 130.32 %, 134.41 % and 133.28 % respectively .The results indicated that trunk-cutting not only improved seed yield and seed quality , but also significantly raised seed germinating capacity , seed germination rate , seed uniformity , and shorten seed germination time .
