摘要
对６年生马尾松（ＰｉｎｕｓｍａｓｏｎｉａｎａＬａｍｂ）实生种子园和无性系（嫁接）种子园的植株进行外施植物生长调节剂处理，其中包括赤霉素ＧＡ４／７、赤霉素ＧＡ３、脱落酸（ＡＢＡ）和萘乙酸（ＮＡＡ）。处理方法有主干环割羊毛脂包理和主干注射。试验结果表明，马尾松种子园植株的雄球花受到赤霉素ＧＡ４／７和脱落酸（ＡＢＡ）这两种植物生长调节剂的处理而显著增加，赤霉素ＧＡ３对雄球花有一定程度的促进作用。环割处理对雄球花的增加也有作用。
GA4/7GA3NAA and ABA were applied to 6_year_old masson pine (Pinus massoniana Lamb.) in seedling and grafted masson pine seed orchard. The application methods were main_stem binding lanolin combined with girdling and main_stem injection. The results indicated that GA4/7 and ABA significantly promoted the formation of male strobil and GA3 also promoted it to some extent. It also showed that being combined with Girdling played a positive role.
