花粉

Morphology of pollen grains of Meliaceae.

Title 栋科花粉形态的研究。

Mellifera fed on transgenic Bt-cry1Ac cotton pollen were significantly higher than those in control.

如果转基因植物的花粉、花蜜中存在转基因蛋白，蜜蜂若摄取那些转基因编码的蛋白质，将会受到直接影响。

Regale Wils, Marrero×Mero Star, Pollyanna ×mixing-pollen, MS + 1 mg/L 6-BA + 0.1 mg/L NAA was a good medium; while for Snow Queen ×L.pumilum, MS + 0.5 mg/L 6-BA + 0.1 mg/L NAA can good for germination.

从试验中所研究的组合来看：White Fox ×L.regale Wils、Marrero ×Mero Star、Pollyanna ×混合花粉的胚在Ms 并附加1 mg/L 6-BA 和0.1 mg/L NAA 的培

The results showed that The tapetum had the characteristics of both glandular tapetum and metamorphous tapetum, pollen abortion is ralated to tapetum.

结果表明：韭菜花药绒毡层兼有分泌绒毡层与变形绒毡层的特点，花粉败育与绒毡层发育异常和提前解体有关。

The result showed that except for transverse diameter, metaxenia effects on fruit longitudinal diameter, fruit shape index, fruit weight, flesh recovery rate, total soluble solids, contents of sugars, acid and Vitamin c in juice, and contents of anthocyanins and chlorophyll in peel were significant based on Duncan's multiple range tests.

结果表明，除果实横径外，在纵径、果形指数、单果质量、可食率、可溶性固形物、总糖、酸、维生素C、果皮花青苷、叶绿素含量等方面花粉直感表现明显，经邓肯氏多重比较测验，差异达显著水平；桂味荔枝自交授粉果在果形指数、总糖含量方面与其它品种授粉果差异不显著。

Under imitated daily field microclimatic conditions for heat stress, the rice cultivar "Jinyou63"(which is a hybrid rice combination) was treated with a consecutive 3-day heat stress during meiosis in phytotron. Anther and pollen tissues at different development stages after subjected to heat stress were sampled and analyzed for transverse abnormalities.

本研究模拟田间典型灾害天气条件，在人工气候箱内对杂交水稻&金优63&花粉母细胞减数分裂期进行连续3 d的热害胁迫处理，对处理后不同发育时期的花药组织取样切片观察，从组织、细胞水平探讨水稻受高温胁迫后花药可能出现的早期异常特征。

The pollen tube enters the female gametophyte from micropylar end and the free nuclei near pollen tube have the average chance to acting as the functional egg.

花粉管从雌配子体的珠孔端进入，珠孔端的游离核行使卵细胞功能的机会是均等的。

As the pollen grains settle on the scales, many adhere to pollination drops, which exude from the micropylar canals at the open ends of the ovules.

作为在刻度上的花粉谷粒长椅，多数黏附在授粉下降，在 ovules 的开着结束从 micropylar 运河流出。

In the offsprings of the aneuploids (P3) with 41~44 chromosomes, there are four types of plants with 29~32 chromosomes. Except the plant with 29 chromosomes, others which appeared abnormal meiosis behavior and poor pollen fertility are mixoploid.

在染色体数为44与41的两种超倍体（P3群体）后代，鉴定出具有29~32条染色体的4种非整倍体，除染色体数为29的植株外，其余均为混倍体，它们的减数分裂异常，花粉育性低。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.

在对危险的南部地区访问时，他斥责什叶派民兵领导人对中央集权的挑衅行为。

In fact,I've got him on the satellite mobile right now.
