花粉

Fern spores and spermatophyte pollen have major roles in plant sex reproduction.

蕨类植物孢子与种子植物花粉在有性生殖过程中都具有重要的作用。

The F〓 spikelet and pollen fertilities of all crosses were investigated.

调查了各组合F〓的小穗育性和花粉育性。

Pollen morphology of six species were similar, all trisected circular shape in polar view, tricolporate. Observed under LM the ornamentation of exine is granular with spinules arranged sparsely and under SEM the basal part of spinule extend.

六种沙蒿的花粉较为相似，极面观均为三裂圆形，三孔沟，孔横长，外壁纹饰在光镜下表面颗粒状，在电镜下为排列较疏的刺，刺基外延。

Purify air, removes in the unusual smell and the fetid odor, absorb and clean air dust, the pollen, tiny bacterium sporangium, the germ and so on.

净化空气、去除烟味及臭味、吸收、清洁空气中的尘埃、花粉、微菌芽孢、病菌等。

Microspore Ye as the feather, small sporophyll sac formed by the polymerization, each polymer capsules formed by four small sporangia, small spores with dual airbags, and airbag Pinaceae pollen is similar to large sporophyll from the central axis and arranged in Brachypodium feather composition, Each Yibing has a shell bucket, each bucket containing shell upright ovules 10-12 months.

小孢子叶枝为羽状，小孢子叶由聚合囊组成，每个聚合囊由4个小孢子囊组成，小孢子具双气囊，与松科植物花粉的气囊相似，大孢子叶由中轴及羽状排列的短柄组成，每一柄上有一个壳斗，每个壳斗内有10—12个直立的胚珠。

Results The values of sICAM-1,sVCAM-1 and tIgE in asthmatic patients were significantly higher than those in control (P＜0.01).There were 19 positive sIgE of artemisia pollen and 12 postive sIgE of dermatophagoides pteronyssinus in 23 patients.There was linear correlation between sICAM-1 and tIgE (R-square=0.502,standard partial regression coefficient=0.097,t=2.841,P=0.021 8) with stepwise regression analysis.

结果 血清sICAM-1、sVCAM-1、tIgE水平测定哮喘组均高于对照组(P＜0.01)；血清中以户尘螨和蒿草花粉的特异性IgE含量增高为主；经多元逐步回归分析提示血清总IgE含量与sICAM-1存在线性关系，其复相关平方为0.502，标准偏回归系数为0.097，t＝2.841，P＝

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.
