子叶

The experiments showed that there were differences in number, size and shape of cotyledons.

在子叶的大小上，有的2片子叶大小基本相似，有的则差异明显。

These large differences were predominantly caused by differences in numbers of annual dicots and perennial, mainly woodland dicots while the higher total species numbers in the Netherlands were mainly the result of an increase in all annual species.

这些大的差异主要是所造成的差异，在人数每年双子叶植物和多年生，林地主要是双子叶植物，而高占总种数的数目，在荷兰，主要是由于增加了，每年都种。

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。

The influences of temperature were significant to the peroxydase activity in cotyledons and radicles and that of salinity was extremely significant to the peroxydase activity in cotyledons and radicles.

温度对子叶和胚根中的过氧化物酶活性有显著影响，盐度对子叶和胚根中过氧化物酶活性有极显著影响。

The results indicated that MDA of both the radicles and cotyledons increased extremely significantly under the low and the high temperature treatments compared with the control, whereas the SOD activities decreased.

结果表明：温度胁迫使胚根中TSP含量均较常温显著或极显著降低，子叶中的TSP含量在低温处理下极显著高于对照，而在高温下与之相反；温度胁迫下，各豇豆品种胚根和子叶中MDA含量均较显著或极显著高于对照；SOD活性变化与之相反，但品种间有差异。

Seeds with membranous or fleshy seed coat; endosperm lacking; embryo straight; cotyledons elliptic, plano-convex, neither convolute nor folded; hypocotyl partly included between cotyledons.

种子有膜质或肉质种皮；无胚乳；胚直立；子叶椭圆形，平凸，不旋卷也不折叠；下胚轴部分藏于子叶间。
