These research results suggested that this plant RNAi vector pCRiRRD3 can effectively perform gene silencing researches on both monocot and dicot plants.

这些研究结果表明，利用单子叶和双子叶双效活性的RRD3启动子而构建的植物RNAi载体，可同时有效地应用于大部分单子叶和双子叶植物的RNAi实验及研究。

The three day old seedlings grown in medium supplemented with 5 mg/L 6-BA were used to prepare the cotyledonary-node explants. The cotyledonary-node explants had one cotyledon and half of the embryonic axis.

选用在高达5 mg/L 6-苄氨基嘌呤(6-BA)的种子萌发培养基上生长3 d的蒺藜苜蓿幼苗，制备获得由1片子叶和半个胚轴组成的子叶节外植体。

The results show that lipid in megagametophyte is preferentially used during germination than lipid from embryo or seedlings and starch accumulation in cotyledon and hypocotyl functioned as temperate storage material.

在子叶中细胞质和质体果糖1，6二磷酸酶的活性都明显高于下胚轴，根和未萌发胚中细胞质和质体果糖1，6二磷酸酶的活性极低，表明子叶和下胚轴进行活跃的蔗糖和淀粉合成活动。

Fruit a usually solitary follicle, sessile or stipitate, dehiscing usually along adaxial suture, sometimes along abaxial one, very rarely circumscissile at base, sometimes indehiscent.

果通常为单生的蓇葖果种子1(或者2)，直立，通常具假种皮，很少无假种皮；种皮厚假种皮有色，肉质；胚乳宿存或无；胚直立；在无胚乳的种子里子叶厚并且肉质，在有胚乳的种子里子叶薄。

Within Old World European Gesneriaceae species (Ramonda myconi and Haberlea rhodopensis), there appears to be a secondary loss of anisocotylous trait back to isocotyly.

特别的是旧世界苦苣苔科中欧洲苦苣苔成员(Ramonda myconi， Haberlea rhodopensis)丧失子叶不等大的现象而成为子叶等大的幼苗。

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。

The purpose of this study was to determine the relationship between abscisic acid and the development and germination of the seed of Pachira macrocarpa.

结果表明：马拉巴栗种子发育过程中，种皮、子叶和胚轴的ABA含量先升高，后下降，最高值出现在花后50 d，最高值分别为791.45、352.68和567.85 ng/g，种皮中ABA具有向内扩散的趋势，含量始终高于子叶和胚轴。

According to mistuned blade design for the asymmetry stator, the wake force on rotor changed from single frequency and higher amplitude to multi-frequency and lower amplitude.

不对称静子叶片分布非谐设计下，转子所受到的激振力由静子叶片均布情况下的单频率高幅值激振力转变为多频率成分低幅值激振力。

To reduce the dynamic stress of rotor blades under the wake of front stator vane,an asymmetry stator mistuned design was conducted.

不对称静子叶片分布非谐设计下，转子所受到的激振力由静子叶片均布情况下的单频率高幅值激振力转变为多频率成分低幅值激振力。

Trunk cylindric, 1-7 m; bark white-gray, gray, or brown, scaly or raised; pollen cones (25-)30-45 × 8-15 cm, microsporophylls 3.5-6 cm; megasporophylls 13-20 cm.

圆筒状的树干，1-7米；树皮白色灰色，灰色，或棕色，有鳞的或提高；雄球花( 25-)30-45 * 8-15 厘米，小孢子叶-6厘米；大孢子叶13-20 厘米 13
