查询词典 pollination

Self-pollination, in general, produces lower percentages of seeds than controlled cross-pollination.

与自然传粉和杂交控制传粉相比，自花传粉常常导致较低的结实率。

Furthermore, our study can provide valuable references for the pollen-mediated gene flow in other self- and wind-pollination crops, such as wheat, for the pollen-mediated gene flow models of wind-pollination crops may follow the same principles.

特别是花粉介导的基因漂移模型的一般形式，在风媒传粉作物间应该是一致的。

Our study can provide valuable references for the pollen-mediated gene flow in other self- and wind-pollination crops, such as wheat, for the pollen-mediated gene flow models of wind-pollination crops may follow the same principles.

特别是花粉介导的基因漂移模型的一般形式，在风媒传粉作物间应该是一致的。

With 3~4-year-old Annona ateznoya Hort. as experimental materials, effects of different pollination ways, degree of petal dehiscence and anther dehiscent time on hand-pollination were studied.

以3~4年生阿蒂莫耶番荔枝为试材，研究了授粉方法、花瓣开张程度和花药裂开时间对坐果的影响。

Self-pollination was brought as the essential reason for causing emptied seeds by former researchers. Based on those studies, potassium antimonate and electron microscopy were used to study the calcium distribution of pollens in the micropylar canal of self-pollinated and cross-pollinated ovules and morphological changes in certain cells undergoing programmed cell death from pollination to fertilization, and observation of histo-chemical changes during microgametopyte development was performed by paraffin section.

前人研究认为自交是华北落叶松产生空粒的主要原因，本论文在此基础，运用焦锑酸钾沉淀法配合电镜观察研究了传粉后到受精前异交控制和自交辅助授粉胚珠珠孔道内花粉的钙分布情况，及此过程中细胞程序化死亡超微结构的变化，并通过石蜡切片研究了华北落叶松传粉后到受精前雌配子体发育过程及细胞内含物的变化，以研究在受精前胚珠内是否存在花粉识别与选择系统，探讨钙信号传导和花粉与胚珠相互作用及细胞程序化死亡的关系。

The nectaries of Ensete glaucum had the highest starch content, and those of Musa basjoo and E. glaucum had fibrillar material presented in nectar ducts. Pollination syndromes among the three species showed high diversity, while inflorescence and flower characters (such as pendant or erect inflorescences, bract color, nectar volume and production over time, etc.) and pollination patterns were highly correlated.

PAS反应显示象腿蕉泌蜜组织中淀粉粒含量高于其他两个种；芭蕉和象腿蕉的蜜腺腔里有许多纤维状物质存在。3种植物的传粉综合征多样化，花序和花的特征(如花序下垂或直立、苞片的颜色、泌蜜量和泌蜜时间等)和传粉样式之间有密切关系。

Common buckwheat, also known as buckwheat, and its flowers have a nectary can scent to lure insects, cross-pollination; Fagopyrum tataricum Tatar, also known as buckwheat, a small flower, no fragrance, self-pollination, artificial hybridization extremely difficult to successfully ; As winged buckwheat buckwheat and rice is the achene edge node as a result of their wings was like thin or plump achenes splitting between the two edge, easy-exposed fruit in the "m" name.

甜荞又称普通荞麦，其花中有蜜腺，能散发香味，引诱昆虫，异花授粉；苦荞又称鞑靼荞麦，花器小，无香味，自花授粉，人工杂交极难成功；至于翅荞和米荞则是由于其所结瘦果棱薄呈翼状或是瘦果两棱之间饱满欲裂，易露出果内的&米&而得名。

Pear belongs to the kind of gametophytic self-incompatibility, so it is necessary to arrange varieties for pollination or perform artificial pollination for stable yield.

梨是配子体自交不亲和果树，生产中必须配置适宜授粉品种或通过人工授粉才能保证产量。

The results showed that the germinating rates were highest when inbred seeds of sweet corn (su 1) were harvested 25～30 days after pollination or whe n effective accumulated temperature from pollination to harv...

结果表明，发芽率最高的收获期及其有效积温分别为：普甜玉米自交系种子于授粉后的 2 5～ 30d ，授粉到收获有效积温为 4 2 7.4～ 5 2 8℃；杂交组合F1代种子于授粉后 30～ 35d ，授粉到收获有效积温为5 2 8～ 6 2 0℃。

Pollination biology on three mixed subpopulations with intermingled Pedicularis rhinanthoides and P. longiflora has been investigated in a three years project. Results show high flowering density can help to enhance pollination facilitation, and then increase reproductive output.

我们选取了两种局限分布在喜马拉雅地区的长管类马先蒿P.rhinanthoides和P.longiflora作了传粉生物学的详细研究，我们的目的在于阐述传粉昆虫在这两种植物生殖隔离中的作用。

In the chapter 2, the theoretic knowledge about the photosensitive resin and the grinding tools was firstly introduced.

第二章阐述了光固化树脂结合剂磨具的相关理论研究。

Do not use the program's indenting or margin-setting features; these will be added during typesetting.
