淡黄花百合花期生物量分配

[目的]研究淡黄花百合（Lilium sulphureum Bakerapud Hook.f.）花期生物量分配,以期为黄花百合的田间管理和合理采摘提供基础资料。[方法]对贵州省务川县境内野生淡黄花百合花期的不同构件进行了称量,用SPSS软件进行相关性检验及回归分析。[结果]淡黄花百合在花期各构件的生物量分配顺序为鳞片〉地上茎〉叶〉花〉地下茎〉茎生根〉鳞茎盘或基盘根。作为百合粉原料的鳞片生物量分配在鲜重时（33.4%）和干重时（41.2%）均为最大。鳞片干重生物量与植株基径、株高及其他构件干重生物量均呈极显著正相关（P〈0.01）。鳞片干重生物量分配与地上茎和地下茎的干重生物量分配均呈极显著负相关（P〈0.01）,与植株生殖构件（花）的干重生物量分配呈显著负相关（0.01〈P〈0.05）。[结论]淡黄花百合植株在养分分配及物质积累与植株的生长上存在着内在协调性联系。在人工栽培过程中应注意控制生殖构件和茎对鳞片生长的影响。
