The concentration of alluvial pollen can be taken as an indicator to distinguish different geomorphological units.

冲积物的花粉浓度可以作为划分不同地貌单元的指标。

Thus we know, withthe alternation of generations, the descendant of pollen plant does not produceboth deterioration or separation and reversed rotation of fertility.

实践证明，应用粳稻花粉植株进行育种是可行的，它能迅速稳定杂种后代和有较高的选择效率。

Any of various weeds of the genus Ambrosia having small, greenish, unisexual flower heads and producing abundant pollen that is one of the chief causes of hay fever.

豚草一种豚草属的杂草，有绿色、雌雄合一的小花冠，能产大量花粉，是引起干草热的主要原因之一

This research discussed the effects of different solvents on the yield of amygdalin from almond pollen.

本研究探讨了从杏花花粉中用不同溶剂提取苦杏仁苷，及提取溶剂的浓度、料液比、超声时间、提取时间对苦杏仁苷提取工艺的影响，并采用紫外分光光度法定性、定量。

The androecium were consisted of 3 stamens,two of which were connate ,separating or partial combination.

摘 要 对南瓜的两性花进行外部形态及结构的研究，结果表明：南瓜的两性花可有子房上位花、子房半下位花和子房下位花三种类型：花萼、花冠均为5，合瓣；雄蕊3，其中有两枚各由两个雄蕊合生而成，分离和部分联合，花药结构特殊，花粉发育正常；雌蕊具有单个或两个柱头及花柱。

By comparing and analyzing the dynamic changes of carbonitride in the floral sex determination of litchi we found that: higher C/N and lower amino acid content are beneficial to androecium differentiation; in contrast, lower C/N and higher amino acid content are adequate for gynoecium differentiation; the amino acid content in androecium is only half of that in gynoecium.

荔枝花性决定中碳氮化合物的动态变化的研究结果发现：C/N较大有利于雄蕊分化，反之则有利于雌蕊分化；氨基酸含量较高有利于雌蕊分化，雄蕊的氨基酸含量仅为雌蕊的一半；脯氨酸与花粉育性存在着密切相关关系。

By comparing and analyzing the dynamic changes of carbonitride in during the floral sex determination litchi,it was found that higher C/N and lower amino acid content were beneficial to androecium differentiation; conversely, lower C/N and higher amino acid content were adequate for gynoecium differentiation; the amino acid content in androecium was only half of that in gynoecium; proline was associated with pollen developmental capacity.

比较分析了荔枝花性决定中碳氮化合物的动态变化，结果发现：C/N较大有利于雄蕊分化，反之则有利于雌蕊分化；氨基酸含量较高有利于雌蕊分化，雄蕊的氨基酸含量仅为雌蕊的一半；脯氨酸与花粉育性存在着密切相关关系。

The conditions for inducing pollen embryoids and calluses and the cytological observations of androgenesis in wheat have been studied.

本工作对小麦花粉胚和愈伤组织的诱导条件和雄核发育的细胞学现象作了研究。

The present work was de-signed to study systematically the changes of anther and pollen during themannitol pretreatment period on physiology and biochemistry;and then the ef-fects of mannnitol pretreatment on androgenesis and anther culture were stu-died.The donor plants used in this experiment grow in the field.

所以本文从以上几个问题出发，以大田生长的植株作为供试材料，首次系统地研究了甘露醇预处理过程中大麦花药花粉在生理生化方面所发生的变化；以及甘露醇预处理后对大麦雄核发育和培养效果的影响。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
