Cv. Shanyou 21 in this report, method of transforming the CpTI and bar gene to peanut with pollen tube pathway technique was studied, the mechanism of the technique in the peanut was discussed; biochemic ingredient changing among the peanut cultivars was analyzed, and genetic distance was studied with RAPD analysis, we hope that these study will be useful to crop breeding.In the two analyses different 19 peanut cultivars were analyzed by RAPD technique respectively.

本论文研究了用花粉管通道法将CpTI和bar基因转入花生品种&汕油523&和&汕油21&的实验方法，初步探讨了花粉管通道法转化花生的机理，并分析了花生品种间生化成分的变化及和RAPD聚类的遗传距离的关系，以期为花生分子育种提供依据。

To the person of Hao pollen allergy, hypersensitive shape may appear when eating the fruit such as peach, mango, litchi; And birchen pollen is the allergen with important spring, allergic to its person when eating the fruit such as apple, plum, apricot, yangtao also may allergic.

对蒿花粉过敏的人，在吃桃、芒果、荔枝等水果时可能会出现过敏症状；而桦树花粉是春季重要的过敏原，对其过敏者在食苹果、李子、杏、猕猴桃等水果时也可能会过敏。

Secondary pollinators are diurnal hawk moths and butterflies. Bombus briviceps and Bombus sp. are nectar gatherers. The mean nectar sugar concentration is 29.5%. The proport ion of seed is 86. 5%. Percentage seed germination under controlled conditions is 23.1 %. Distances that seeds are ejected ranged from 0.58-1.17 m. The distances that pollen spread is 29cm. Pollen viability is highest on the day of anthesis and thereafter decreased.

匍匐凤仙花的主要传粉者是蜜蜂和熊蜂，次要传粉者为白天活动的天蛾和蝴蝶，另外还有两种花蜜窃取者；花蜜糖平均浓度为29.5％；种子产生率为86.5％，种子萌发率为23.1％，种子散布距离为0.58-1.17m；花粉流为29cm；花粉活力在第一天最高，第二天次之，第三天显著减弱；P／O值为

Any of various brightly colored Australasian parrots having a tongue with a brushlike tip that is used to feed on nectar and pollen .

花粉显像密度计的计算结果，可以表明每一平方毫米孔径上吸入的花粉粒数。

Pollen-tube growth down the style is both positively and negatively chemotropic; the tube grows toward chemicals secreted by the pistil, and away from atmospheric oxygen.

花粉管沿着花柱的生长是既有正向性也有负向性的：花粉管向着由雌蕊分泌的化学物质生长，同时远离空气中的氧气生长。

An out crossing plant needs to transfer its pollen to the stigma of a conspecific plant, and receive pollen from a conspecific.

异型杂交植物需要将其花粉转移到同种植物的柱头上，并接受同种植物的花粉。

An out crossing plant needs to transfer its pollen to the stigma of a conspecific plant, and receive pollen from a conspecific.

传粉异型杂交植物需要将其花粉转移到同种植物的柱头上，并接受同种植物的花粉。

Genetic losses arise from the influx of 'wild' conspecific pollen into seed orchards.

林木种子园花粉污染是影响种子园种子遗传品质的重要因子，由于野生同种花粉进入种子园而增加遗传损失。

An out crossing plant needs to transfer its pollen to the stigma of a conspecific plant, and receive pollen from a conspecific.

但是大多数开花的双子叶植物，依靠昆虫，鸟，蝙蝠或小型哺乳动物来传播花粉，作为交换，这些动物或以花蜜或以花粉本身为食。

Solid medium was using to study the effect of sugar, boron, calcium on pollen germination and pollen tube growth of Corylus heterophylla Farnch.× C. avellana L..

采用固体培养基研究了不同浓度的蔗糖、硼和钙配比对杂交榛花粉萌发及花粉管生长的影响。

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。
