摘　　要：对筇竹种子主要内含物成分及不同种源种子的播种品质进行了研究。结果表明:1)筇竹种子主要有机养分为可溶性蛋白质、可溶性糖、可溶性淀粉、维生素C和粗脂肪,含量分别为12.54%、8.26%、2.48%、3.81%和12.97%,其中粗脂肪含量最高,可溶性淀粉含量最低;2)筇竹种子中氨基酸含量在0.36～10.50 g/kg,占总营养成分的1.23%～35.78%,其中天冬氨酸含量最高;3)筇竹种子矿质元素含量:钾含量最高,达到3 280 mg/kg,其次是磷,为672 mg/kg,铜的含量最低,为2.14 mg/kg;4)不同种源筇竹种子,在千粒质量、含水量和发芽率方面存在显著性差异,而形态特征上差异不明显;5)在不同环境条件下筇竹种子发芽率不同,其中在室内无菌条件下发芽率最高,为90.00%,在苗圃带菌环境下发芽率最低,为86.66%。The main components of Qiongzhuea tumidinoda seeds and the sowing quality of the seeds of different provenance were studied. The results showed that : 1) The main organic nutrients of fumirfireorfa seeds were soluble protein, soluble sugar, soluble starch, vitamin C and crude fat, which were 12.54%, 8.26%, 2.48%, 3.81% and 12. 97% in content, respectively. The content of crude fat was the highest while that of soluble starch was the lowest;2) The amino acid content of fumirfireorfa seeds was 0. 36-10. 50 g/kg, accounting for 1. 23%-35. 78% of the total nutrients, and the content of aspartic acid was the highest;3) Among the mineral element content of fumirfireorfa seeds, The potassium content was the highest at 3 280 mg/kg, followed by phosphorus at 672 mg/kg and the copper content at 2. 14 mg/kg, which was the lowest;4) fumirfireorfa seeds of different provenances showed the significant differences in 1 000 - grain quality, water content and germination rate, but the differences in morphological characteristics were not obvious;5) The germination rate of fumirfireorfa seeds was different under different environmental conditions, which was the highest under indoor aseptic conditions, i. e., 90. 00%, while the lowest at 86. 66% under the nursery environment.
