再将放射松的种子与孢子果的细粉加水混合，则每粒种子约含1.9 × 106个孢子。

The results indicate that: the macroslructural features of seed surface, including smooth type, rugulose type and tuberculate type, may suggest the evolutionary trend from smooth type to rugulose type, from rugulose type to tuberculate type; the microstructural features of outer epidermis can be divided into two types, viz. verrucate type and reticulate type. The former included S. grandiflora, S. chinensis, S. elongata, S. lancifolia, S pubescens, S. henryi, S. repanda, the latter included S. propinqua and .S. plena.

结果表明：该属的种子宏观形态呈现平滑、细皱纹或瘤状突起，并认为五味子属种子形态可能有从平滑到有细皱纹再到有瘤状突起的演化趋势；该属种皮表面微观形态可分为疣状突起型(如：大花五味子、北五味子、东亚五味子、狭叶五味子、毛叶五味子、翼梗五味子和二色五味子)和网纹型。

Gibberelin (GA3) with different density of 100 mg/L、200 mg/L、400 mg/L and the polyethyleneglycol with different density of 10%、15%、20%、25% were used to treat Setaria sphacelata seeds in this study.

埃塞俄比亚科学家发明了能抗长期干旱的高梁种子，这种种子也能抗杂草独脚金(Striga ，一种寄生草)，这种杂草是导致非洲作物歉产的主要原因。

As time of accelerated aging increased,abscisic acidcontent of cotyledons andaxes was increased dramatically.ABA contentwas 4 times more in seed axes aged for 5 daysthan in unaged ones and 1 time more in cotyledons.

随着人工加速老化，菜用大豆种子胚轴、子叶内ABA含量都呈增加的趋势，老化5天种子胚轴内ABA含量为未老化的5倍多，子叶内则为2倍多。

Multiflorus collected from the Hengchun Botanical Garden at the southern tip of Taiwan only germinated with 5% at alternating temperatures of 30/20℃ for 8 wk and reached 45% after 12 wk. All ungerminated seeds were found to be empty or dead by cutting test at the end of 12 wk.
