对马来甜龙竹Dendrocalamus asper (J. A. et J. H. Schult) Backer ex Heyne、黄竹D. membranaceus Munro、巨龙竹D.sinicus Chia et J. L. Sun、“大白竹”Schizostachyum sp.、灰香竹Chimonocalamus pallens Hsueh et Yi和筇竹Qiongzhuea tumidissinosa Hsueh et Yi等6个坚果状颖果、典型颖果和浆果状颖果3类竹子种子进行了萌发和贮藏试验。6个竹种种子均未观测到明显的休眠期,新鲜的成熟种子播种后5~15 d内发芽,约15 d内完成整个发芽期。场圃发芽率以坚果状的马来甜龙竹(发芽率84.0%)、黄竹(81.0%)表现较好;典型颖果类中,巨龙竹(43.3%)和大白竹(73.5%)种子发芽率差异明显;而浆果状的筇竹的发芽率最低(25.0%)。MS+BA0.5+NAA0.2的培养基适合于竹类种子萌发。室温(20~25℃)层积的发芽率明显高于4℃层积的发芽率。浸种10 d后黄竹、马来甜龙竹、大白竹、筇竹的种子的发芽率降至0~5.5%。在4℃冷藏或室温阴干贮藏条件下,三类竹子种子发芽率随着时间的增长而急剧下降,贮藏3个月后,发芽率下降到0~4.0%;种子拌土对延长其种子寿命有一定促进作用。
