对...授粉

The experiment material is apricot and almond in this paper,passed TTC method to carried on examination the agnate pollen of vitality before pollination;after the investigation fruit set percentage,using of DPSv3.01 analyzed the date;the pollen tube behavior and bourgeon were observed by means of flurescence microscopy;the orthogonal design was used to optimize SSR amplification system of apricot hybrids in five factors at four levels respectively;making use of the new SSR-PCR system analyse the 50s hybrids.

本文以仁用杏及扁桃为试验材料，通过TTC染色法对授粉前父本花粉的活力进行了测定，运用DPSv3.01专业版数据处理系统软件对授粉后坐果率的调查数据进行了分析；利用荧光显微技术对花粉在柱头的萌发情况及花粉管的生长状况进行了动态观察；采用正交设计对仁用杏杂交苗SSR-PCR反应的5因素4水平进行试验；在新体系的基础上对50个杂交苗进行了分析。

The results suggest: the three culturalss pollen germination percentage were more than 60% 4 h after cultured in liquid culture medium composed 10% sucrose, 24℃; Florescence most concentrated April third-tenth (2003); For Zaomeisu and Qiyuesu ,their anthotaxy and flower self setting fruit percentage were more than 90%,except for China pear 1, anthotaxy self setting fruit percentage was 48.3%, flower self setting fruit percentage was 33.1%; Their cross-compatibility was higher, anthotaxy and flower self setting fruit percentage almost reached 100%, the lowest also reached 94.9%, but last self-compatible gathering fruit percentage was lower comparatively and fruit average seed numbers were lower, while cross-compatible gathering fruit percentage and fruit average seed numbers were closed to that of nature pollination.

对梨品种亲缘关系很近的早美酥、中梨1号、七月酥等进行的花粉发芽率、花期调查、自交亲和性、异交亲和性调查的结果表明：三者的花粉在10%的蔗糖液培养基上，24℃左右培养4h后花粉发芽率均能达到60%以上；三者的花期大都集中在4月3日-10日(2003年)；早美酥、中梨1号、七月酥的自花授粉坐果率，除中梨1号的花序自花授粉座果率为48.3%，花朵自交座果率为33.1%外，早美酥、七月酥的花序自交座果率和花朵自自花授粉座果率均达到90%以上；它们的异花授粉坐果率更高，在本试验中花序坐果率和花朵坐果率都可达到94%以上，但最终采果率自花授粉的相对低一些，果实平均种子数也低，异花授粉的最终采果率和果实平均种子数与自然授粉条件下的近似。

The breaking parts of anthers in the four longerstamens were face to the reverse side of pistil and winding,but thedevelopments of the self-compatibility lines were regular.A greatdeal of callose was observed in stigma and pollen tuber both in theself-compatibility and self-incompatibility pollination.

对亲和性授粉和不亲和性授粉的荧光显微观察表明，无论是亲和性授粉还是不亲和性授粉，在柱头组织和花粉管组织中均可以形成大量的胼胝质，未发现胼胝质的产生和数量与自交不亲和性的识别反应有什么因果关系。

Petal and nectar may be a advertisement in attracting pollinators, however, stigma and pollen were indistinctive in attracting pollinators.

花冠和花蜜对授粉昆虫具有较强的招引作用，而柱头和花粉的招引作用似乎不明显。

The result indicates that honeybee is the most ideal pollinator, and honeybee industry has played a vital role in maintenance of environment development and protection of ecological equilibrium.

研究结果表明，蜜蜂是最理想的授粉昆虫，蜜蜂产业在维护环境发展和保护生态平衡中具有重要作用，当前要大力宣传蜜蜂授粉对农业的增产和维护生态平衡的作用，出台保护授粉的法规，培育龙头企业，推进产业化进程，带动农业增产和农民增收，把保护蜜蜂提高到保护人类的高度来认识。

Unicolor after 3 hours of pollinating in that the rate of ovary enlargement and embryo forming in this period is respectively high.While, the form of transferring is also tested, which shows that the position and percentrite of DNA are of great effect on Lilium davidii var.Unicolor.

通过对授粉后在柱头或花柱断面滴加后的结实与有胚种子的分析，表明滴加的部位选择在柱头滴加为宜，采用切割柱头的花柱断面滴加时，子房膨大和结实率会受到影响而降低。

Unicolor provides us a set of improved parameters based on the rata of fruit and embryo seeds.After pollinating the conclusion of the items of ovary enlargement, fruitfulness, embryo seeds of transferring exogenous DNA should be better transferred to Lilium davidii var.

在导入时，通过对授粉后4个时间段滴加外源DNA的子房膨大、结实和有胚种子情况的研究后得出结论，选择外源DNA滴加的时机在授粉后3h左右较为适宜，此时的子房膨大率和有胚种子率均较高。

Effects of different fruit-retaining reagents upon fruiting on Yunan seedless wampee;2. To probe into the seedless reason of fruit of the Linyuan 1 seedless wampee ,the Linyuan 1 seedless wampee is observed at its flower organs, pollen quantity and degree of satiation, and germination, and compared with the seed wampee.

为了探讨林院 1号无核黄皮果实无籽的原因，于 1992年～ 2 0 0 0年在广西大学林学院观察林院 1号无核黄皮的花器、花粉数量及饱满程度、花粉萌发情况，并和有核黄皮比较；采用随机区组试验设计，对林院 1号进行自然授粉、去雄不授粉套袋、去雄后用有核黄皮花粉授粉并套袋的授粉试验；观察林院 1号的授粉受精过程。

Conversely the seeds had the longest mean length of incubation time and germination peak value when pollinated every day.4 The planting date had effects on yield and quality of carrot seeds from different seed umbels and poisons of seed disc, also had effects on the growth and development of carrot steckling.

不同授粉时期对种子产量、千粒重、发芽率、发芽势的影响不显著，仅对种子的平均发芽天数、发芽高峰日分别存在显著、极显著影响，且&每日授粉&的种子平均发芽天数及发芽高峰日最长，&隔1日授粉&的种子平均发芽天数及发芽高峰日最短。

Farmers have to import bees, rent bees, and move bees around in order to cross pollinate crops.

农民要进口蜜蜂，蜜蜂的租金和移动蜜蜂周围，以便对授粉作物。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
