That's because pollen allergies are often seasonal, like ragweed during the fall, grass pollen in the spring, and cedar fever in December or January.

这往往是因为花粉过敏季节，像豚草在秋天，草花粉的春天，雪松、发烧或12日。

Purpuraristatus, the growth, fertility, chromosome configuration, EST isozyme etc. were analyzed in this paper. The results showed that the growth potentiality of (E. sibiricus×E. purpuraristatus) F2 and (E. purpuraristatus×E. sibiricus) F1 were much stronger than their parents, the plant height of the former was 143.2 cm. The whole plant was reseda, the latter was 129.7 cm. The spike nodding of two hybrids were in the middle of their parents, the anther was yellow; the pollen fertility was 0.02%~0.03%, seed set was 0; the average chromosome configuration of former pollen mother cell at PMC M Ⅰ was 6.90Ⅰ+14. 02Ⅱ, the latter was 7.82Ⅰ+13.59 Ⅱ, and lagging chromosome and bridge fragment were observed at meiosis anaphase Ⅰ the EST of the two hybrids F1 and their parents at tillering stage was some certain different in locus, number and intensity.

结果表明，正交F1和反交F1植株的生长势均很强，正交F1株高143.2 cm、全株浅绿色，反交F1株高129.7 cm、全株灰绿色；正、反交F1的穗型均呈双亲中间型，花药呈黄色，花粉可育率0.02%~0.03%，结实率为0，说明杂种高度不育；正交F1的花粉母细胞减数分裂中期Ⅰ平均染色体构型为6.90Ⅰ+14.02Ⅱ，反交F1为7.82Ⅰ+13.59Ⅱ，减数分裂后期丁有落后染色体和染色体桥等不规则现象；亲本及其正、反交杂种F1分某期幼叶的EST同工酶酶带的位点、数目和强弱均存在一定差异，可作为亲本及杂种在蛋白质水平识别的重要依据。

Stamens inserted at base of corolla; filaments free, broad at base; anthers oblong-ovate, pilose on back, long pilose at apex, exserted; pollen carriers spatulate, pollen tetrads in masses, translator oblong, retinaculum ovoid.

雄蕊花冠的着生的在基部；花丝离生，宽的在基部；在背面上卵形，具柔毛的花药长圆形，具长柔毛在先端，外露；花粉搬运工匙形，在群众内四合花粉，载粉器长圆形，卵球形。

Stamens inserted at corolla base; filaments distinct, threadlike, alternate with minute teeth; anthers connivent, adnate to stigma head, appendages membranous; pollen tetrads in solitary masses in each anther cell, pollen carriers erect; retinaculum minute, dilated at base.

在花冠基部着生的雄蕊；离生的花丝，线状，互生的具小牙齿；靠合的花药，贴生于柱头头状花序，附属物膜质；在每间花药小屋，花粉搬运工直立里的在单生群众里的四合花粉； retinaculum小，膨大的在基部。

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。

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。

The ligand encoded by SCR gene is a small pollen coat protein present on the surface of pollen grains. The receptor localized to the plasma membrane of the stigmatic papillae on the surface of the pistil is encoded by SRK gene.

配体是位于花粉粒表面的一个小的胞被蛋白，由SCR基因编码；受体是位于柱头乳突细胞原生质膜上的跨膜的蛋白质激酶，由SRK基因编码。

Results show stigmatic pollen load of pollinated flower is significantly higher than ovule number/ovary for all the studied plants; pollen grains deposited on stigma are enough to fertilize all of the ovules. Results also seed abortion is common.

虽然花部隔离是不完全和不彻底的，但在维持马先蒿属植物间的生殖隔离和种间特征，尤其是避免普通传粉者所造成的花粉干扰是十分重要的。

In addition, they have relatively longer flower tubes, higher stigmatic pollen loads, bigger pollen size and a shorter blooming period for individual flowers. Finally, the author discusses the evolutionary significance of floral design in genus Pedicularis.

如我们发现，由柱头特征不同导致传粉效率的差异，这种传粉效率与马先蒿属植物的花冠管成正比，与单花开放时间成反比，与花粉大小成正比，本文还着重讨论了这些相关性的适应性意义。
