Result There was no significant difference to the number and length of parenchyma cell in the uppermost internode between Shuangdi Pei eS and Shuangdi S in meiosis and dikaryon pollen stages;there was significant difference to those in tikaryon pollen stage, and there was very significant difference to those in anthesis and the 7th day after anthesis,and on the 7th day after anthesis,the difference to the number and length of parenchyma cell in the uppermost internode between Shuangdi Pei eS and Shuangdi S was the greatest.

长穗颈双低培eS与双低S穗颈节间薄壁细胞数及细胞平均长度在减数分裂期和二核花粉期差异不明显，于三核花粉期差异达显著水平，始花当天和始花后第7天均达极显著水平，其中始花后第7天时两者的差异最大。

The results showed that the pollen grains of B.biternata is spheroidal and the diameter is(27.0μm) with 3-colposate,the pollen exine sculpture with concentraed echinate

结果显示：金盏银盘(B.Biternata)的花粉粒为球形，直径27.0μm，具三孔沟，花粉粒表面具密集的刺状雕纹

Parviflora is spheroidal and diameter is 25.5μm with 3-colposate,the pollen exine sculpture with concentrated echinate

小花鬼针草(B.parviflora)的花粉粒为球形，直径25.5μm，具三孔沟，花粉粒表面具密集的刺状雕纹

The pollen grain of B.bipinnata is prolate and the size is 37.0μm×26.7μm with 3-colposate,the pollen exine sculpture with thin echinate.

婆婆针(B.bipinnata)的花粉粒为长球形，大小为37.0μm×26.7μm，具三孔沟，花粉粒表面具稀疏的刺状雕纹。

A procedure had been studied on cryopresrvation of Loquat Eriobotrya japonica Lindl.

摘要采用花粉干冻法对枇杷花粉超低温保存进行了研究。

In a compatible pollination, pollen germinates to extrude a tube that penetrates the stigma and grows extracellularly through the stylar tissues to ovules.

当花粉通过自交不亲合的筛选后，萌发的花粉管会穿透柱头并沿著花柱朝胚珠生长。

The spinules of Rhoiptelea are similar in form and size to those of Gentianales. The spinules consist of rods of ca 70 nm in width.

马尾树花粉上的小形与大小和一些胆目植物的花粉很相似，小是由宽约70 nm的棒物所组成。

Cultureof the pollens of three apple varitieties on a medium amended with15%sucrose and 1%agar showed that germing abilities of Fuji,Gala and Telemon were72%,77%,82%,respectively.

本文以嘎拉，富士，telemon为试材，采用不同培养基来测定花粉的发芽率，以便了解苹果花粉发芽所需要的适宜的培养基。

Morphology of sexual reproduction abortion in'High Noon', a distant hybridization cultivar of tree peonies(P.delavayi var. lutea×P. suffruticasa), was systematically investigated with light microscopy and cross. The results indicated that:(1)The stamens matured earlier than the gynoecia and pollens dispersed at the early stage of anthesis but the rate of normal 2-celled pollens were merely 2.41%.

采用光镜和杂交等方法对牡丹远缘杂交一代品种'正午'有性生殖败育进行系统形态学观察发现：(1)雄蕊较雌蕊先成熟，初花期即散粉，正常2-细胞花粉仅占2·41%，且花粉在多种培养液中、在自身和其它两种柱头上均不萌发；柱头在谢花期大量分泌粘液，进入最佳授粉状态；(2)同一胚珠中多个大孢子母细胞减数分裂高度不同步，胚囊发育与受精延迟，部分胚乳游离核在细胞化时期分裂异常；(3)自花及品种内异花授粉不结实，天然授粉结实率为0·053‰~0·130‰。
