  1. Degenerate oligonucleotides to highly conserved regions of cucumis melo 1 - aminocyclopropane - 1 - carboxylic acid ( acc ) oxidase gene were used to prime the amplification of fragment of 128bp by ploymerase chain reaction ( pcr ) in samples of genomic dna from fruit of cucumis melo l. cv hetao flesh, which was cloned into plasmid vector pmd - 18 - t. the clon of antisense orientation were selected, and it was inserted downstream of camv35s promoter and enhancer " " of tmv into the plant expression vector pbinyxw, antisence expression vector pbinya was constructed. at the base that pollination and fertilization of cucumis melo l. cv hetao was studied, using pollen tube pathway transformate cucumis melo l. cv hetao, 76 fruit had been obtained, moreover, hardness and content of sugar were analysed

    本實驗以河套蜜瓜果肉基因組dna為模板，用甜瓜acc氧化酶基因特異寡核苷酸鏈為引物進行pcr擴增，得到128bp的擴增產物。將得到的擴增產物克隆到質粒載體pmd - 18 - t上，篩選反向克隆，然後將其反向構建到植物表達載體pbinyxw的camv35s啟動子和tmv增強子「 」的下游，構建成反義表達載體pbinya 。並在對河套蜜瓜授粉受精生物學研究的基礎上，通過花粉管通道法轉化河套蜜瓜，共獲76顆瓜，並進行了硬度和含糖量的分析。
  2. Internal fertilization takes place in the seed plants and some clubmosses and ferns, often by means of a pollen tube

    種子植物、某些石松和蕨類植物依賴于花粉管完成體內受精。
  3. During the process of fertilization, pollen lands on the stigma, a tube grows down the style and enters the ovary

    授精的過程中，花粉到達柱頭，花柱低下來進入子房。
  4. About 2s after fertilization in 17, sperms arrive at micropylar tube ; 3s, sperm penetrates into ovum where cytoplasm is sunken ; 5s, the spermaster come into being ; 20s, fertilization stopper appears ; 60s, sperms in micropylar apparatus begin to disaggregate

    精子在受精2s到達精孔管， 3s進入卵子， 5s形成精子星光， 20s形成受精塞， 60s后精孔器內精子開始溶解。有多精入卵現象，極少數卵子多精受精。
  5. With test tube, or " in itro, " fertilization, doctors unite donated sperm and eggs outside the mother ' s body

    醫生通過試管或「在體外， 」受精，使捐贈的精子和卵子在母體外結合。
  6. The fertilized eggs of hemibnrbus lubco have been observed by sem, tem and om, and main events of fertilization biology have been studied, too. the results suggest : the micropylar apparatus, being composed of vestibule and micropylar tube, is deeply sunken with a short tunnel

    對唇（魚骨）受精過程中發生的主要事件進行組織切片、透射和掃描電子顯微鏡觀察，結果表明：精孔器屬深凹陷、短孔徑型，精孔管一次只能通過一個精子。
