正如AskOxford.com上的专家解释的:正真的果实是从花朵底部的子房成长出来的,含有植物的种子(虽然人工培育的种类也许没有种子)。

This indicated that the seeds of Cyclocarya paliurus was relieving dormancy and prepared for germination.

这也预示着,青钱柳种子在不断的打破种子的休眠,为萌发做好准备。

With the seeds from nine natural Cyclocarya paliurus populations as test materials, their phenotypic traits, including 1000-seed weight, seed size, seed diameter, seed thickness, and seed diameter/thickness ratio, were investigated, and the phenotypic diversity among and within the populations were studied by the methods of ANOVA analysis, hierarchical cluster analysis, and correlation analysis.

以青钱柳分布区内的9个天然群体种子为试材,对种子千粒重、体积、直径、厚度和径厚比5个表型性状进行了系统的比较分析,采用方差分析、相关分析及聚类分析等方法对群体间和群体内的表型多样性进行探讨。

One hypothesis is panspermia, which suggests that 'seeds of life' exist everywhere around the universe, and that life on earth started when these 'seeds' came here, probably by a meteor.

一种假设是胚种论,它认为宇宙到处存在&生命的种子&,地球上之所以开始有生命是因为这些&种子&到达了地球,可能是随着流星而来。

对蝶形花科,锦鸡儿属落叶灌木柠条(Caragana spp。)的种子萌发、幼苗生长、土壤种子库和营养繁殖等更新生态位特征及其与荒漠植被恢复的关系进行了综述,旨在为柠条的繁殖生物学和恢复生态学研究提供更新生态位方面的理论依据。

在荚果水平上,苜蓿荚果内种子在形成过程中表现出明显交替败育的趋势,其中从果实基部算起偶数位置的胚珠形成种子的机会更大。

With different concentrations of polyethylene glycol (PEG6000), the treatment of water stress was simulated: With the decrease of water porential, the germination percentage, speed and index decreased in total and increased at the temperate water stress (-0.2MPa), indicating that A. pedunculata Pall. has drought tolerance in certain extent.

用不同浓度的PEG6000模拟土壤干旱对种子萌发进行人工水分胁迫处理,随着水势下降,种子发芽率、发芽速度、发芽指数及发芽活力呈下降趋势,在轻度水分胁迫下(-0.2MPa)发芽率有所上升,表明长柄扁桃具有一定的抗旱性。
