| 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%。

| Abstract: | 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 Q. tumidinoda 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 Q. tumidinoda 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 Q. tumidinoda 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) Q. tumidinoda 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 Q. tumidinoda 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. |
