人工授粉

All of these results could be provided the basic references for studying the burliness rate and controlled pollination of bamboos.

这些结果也为研究各竹种的不结实和实行人工授粉等研究提供基本的参考依据。

In our results, the sweetsop flowering time was during the last third of May to the early July in Beijing greenhouses. 6.9 to 6.23 was the very stage which had more flowers and high set rate. We could use this period for artificial pollination to enhance the output.

结果表明：在北方日光温室环境条件下，番荔枝自然开花集中时间为5月下旬到7月上旬，6月9~23日，是番荔枝开花数量多并且坐果率较高的时期，生产中可充分利用这一时期的人工授粉提高坐果量。

We observed the flowering and fruiting process of sweetsop (Annona squamosa L.), to found the best time for artificial pollination in Beijing greenhouses.

观察北方日光温室环境条件下，番荔枝的开花结果特性；研究人工授粉最佳时期和授粉技术，为日光温室番荔枝栽培提供技术支撑。

Four varieties and five different groups (25-200 plants ) were used for 3 years in the research, and anemogamy and entomophilous pollination in nature was used as the check,and agronomical character, chromosomes and isoenzymes were studied.

连续3年，选用4个品种，设25～200株5种不同群体，采用人工授粉等5种授粉方法，以自然条件下风、虫自然传粉为对照。从农艺性状调查，染色体观察及同工酶分析方面进行研究。

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。

Plants with hypogenetic stamina or ungerminated pollen were observed.

转基因植株自交不能结实，用转基因植株花粉对正常植株进行人工授粉，不能正常结实，表明转基因植株花粉是不育的。

The highest fruit set percentage was obtained when hand-pollination was done in one day (at the stage of half opened petals) before the anthers naturally dehisced. Hand-pollination could increase fruit set from 2 days to 4 hours (at the stage of tiny dehiscent petals to over half-opened petals) before the anthers naturally dehisced. The pistil compatibility was strong and fruit set percentage with hand-pollination was the highest one day before the anthers naturally dehisced (at the stage of half-opened petals).

从花药自然裂开前2 d到自然裂开前4 h（相当于花瓣呈微张开到超过半张开状态），雌蕊都具有容受性，这期间进行人工授粉能提高坐果率，但以花药自然裂开前l d（相当于花瓣呈半张开状态时），雌蕊容受性最强，人工授粉坐果率最高。

The absorption and distribution of chromium were studied in ryeusing nutrient culture technique and pot experiment.

采用不同浓度K2CrO4(0，0.4，0.8和1.2 mmol/L)的Hoagland营养液处理黑麦幼苗，测定铬在黑麦体内的亚细胞分布、铬化学形态及不同部位的积累。

By analyzing theory foundation of mathematical morphology in the digital image processing, researching morphology arithmetic of the binary Image, discussing two basic forms for the least structure element: dilation and erosion.

通过分析数学形态学在图像中的理论基础，研究二值图像的形态分析算法，探讨最小结构元素的两种基本形态：膨胀和腐蚀；分析了数学形态学复杂算法的基本原理，把数学形态学的部分并行处理理念引入到家实际应用中。
