Pollen morphology Pollen grains of one hundred and four species belongomg to twenty-three subsections of seven sections of Rubus L.

花粉形态通过扫描电镜观察了中国悬钩子属7组23亚组共104个种的花粉形态。

A population of 48 individualswas developed from cross'91-42-51' ×'Ruiguang 2', and was used to find molecular markers linked to characters as peach or nectarine, yellow or white flesh, male sterility or male fertility by bulked segregant analysis.

以91-42-51 ×瑞光2号的杂交后代共48个单株为试材，采用集群分离分析法，对桃果实的有毛/无毛、白肉/黄肉以及无花粉/有花粉3 个性状进行了分子标记研究。

The mean number of pollen grains per stigma ranged from 5 to 18, most of which were from self-pollination.

花柱头上的平均花粉量为5～18个，但主要为来自自花的花粉。

The microspore germination of self-pollination,self-plant-pollination and cross-pollination and the pollination microspore germination in and outside of stigma were observed with fluorescence microscopy.

Some people suffer the nuisance of seasonal hay fever , snuffling and sneezing as pollen flows through the air .

一些人饱受季节性花粉热之苦，当遇到空气中流动的花粉时抽鼻子和打喷嚏。

Some people suffer the nuisance of seasonal hay fever, snuffling and sneezing as pollen flows through the air.

一些人患有季节性花粉病，花粉通过空气传播时，他们就会抽鼻子和打喷嚏。

To understand the possible influence of jasmonates on pollen germination,the effects of dihydrojasmonic acid and methyl jasmonate on sponge gourd and rape pollen germination were investigated.

为进一步探查茉莉酸类植物激素对花粉萌发的影响，研究二氢茉莉酸和茉莉酸甲酯对丝瓜和油菜花粉萌发的效应。

Sponge gourd and rape pollens from spikelets of natural anthesis were harvested and immediately spread onto pollen germination mediums with or without DHJA or MeJA of different concentrations.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
