摘要: 浆果苋[Deeringia amaranthoides (Lam.) Merr.]具有祛风利湿、通经活络的功效,是壮族的民间特色药。试验对其种子的形态特征、千粒重、种子发芽条件、种子贮藏条件、不同产地种子质量等进行了比较,旨在为其种子检验和种苗繁育寻求依据。结果表明,浆果苋种子发芽的温度为20~30 ℃,最适宜的发芽温度是25~30 ℃,低温和高温都抑制其萌发。浆果苋种子小,千粒重约为0.3 g;种子寿命短,常温保存约8个月其发芽率下降为0;不同产地采收的成熟种子质量差异不大。

Abstract: Deeringia amaranthoides (Lam.) Merr. is a folk drug for the Zhuang nationality, which has the effect of "Qu Feng Li Shi and Tong Jing Huo Luo". Experimental studies on its morphological characteristics, 1 000-grain weight, germination conditions, storage condition and quality from different places were conducted seeking basis for seed testing and seedling breeding. The results showed that seed germinated temperature was 20 to 30 ℃, with the optimum at 25 to 30 ℃. High or low temperature markedly restricted seed germination. The seed is tiny, as its TKW is about 0.3 g. The seed germination rate would reduce to 0 when storage at normal temperature for 8 months. The different in quality of seeds from different places is little.

Key words: Deeringia amaranthoides (Lam.) Merr., seed, biological characteristics
