breeding stage 中文意思是什麼
breeding stage
解釋
繁殖期-
The breeding population must cycle through a selection phase before each successive regeneration stage.
每個后續世代更換之前，育種種群必須經過一個選擇循環。 -
The research adopts that hu - - ifn gene were introduced into the nuclei of oocytes or cytoplasm of grass carp to develop anti - disease transgenic grass carp breeding researches, combing the adva ntag e of hu - - ifn gene and breeding by genetic engineering, with an aim of finding out an effective way of solving antivirus of hemorrhagic virus of carp completely. in research of transgenic fish, hu - - ifn gene ( recombination gene ) is cutdown and introduced into the nuclei of oocytes or cytoplasm of grass carp at one - cell or two - cell stage via micyoinjection by narashige micyoinjection apparatus
本研究的目的在於以人的-干擾素基因（ ifn - ）作為目的基因，與鯉魚-肌動蛋白基因啟動子在體外重組，利用原核顯微注射轉基因技術將人-干擾素基因導入草魚基因組而開展的抗病轉基因草魚育種研究，其結合了干擾素和基因工程育種抗草魚出血病病毒的優點，以期獲得對草魚出血病具有天然抗性的轉基因魚，並在此基礎上培育出草魚抗病新品系。 -
Unicolor and lilium asiatic hybrids or cultivars in lilium asiatic hybrids were researched with their parents by karyotype, soluble protein, esterase isoenzyme and peroxidase isoenzyme. the results provided identification markers of cytology and biochemistry for hybridization at the early stage in lily breeding programs. the cluster analysis according to similarity coefficient of soluble protein and peroxidase showed that " yellow " and " omega " have the most closest relation in lilium asiatic hybrids
本研究對百合屬幾個植物的親緣關系進行了可溶性蛋白質、過氧化物酶同工酶分析，同時對亞洲百合雜交系內雜交及其與原種系間的雜交後代進行了核型、可溶性蛋白質、過氧化物酶和酯酶同工酶分析，以期為百合屬植物親緣關系分析提供生化依據，以及為雜交後代的早期鑒定提供細胞學、生化水平的檢測指標。 -
Factors of inducing dormancy, determining the stage of flower initiation and dormancy development, the methods of avoiding dormancy and stimulating adequate and uniform budburst, the growth and development of tree and the cultural management, the cause of secondary dormancy and the methods of avoidance of secondary dormancy, and the breeding of non - dormant cultivars are the critical points for non - dormancy culture
溫帶地區無休眠栽培的研究重點是：自然休眠誘導因子的確定；花芽分化進程及自然休眠進程的精確界定；避免進入深度休眠及促芽整齊萌發的配套技術；無休眠栽培條件下樹體的生長發育規律及樹體綜合管理技術；二次休眠現象發生的原因和克服措施；無休眠品種的選育。 -
Genetic markers enable plant breeders to begin their selection at the cell stage by looking for the gene responsible and checking at an early stage of cross - breeding, whether the desired gene has been inherited by the offspring plant, instead of having to go through the process of cross - pollination and then growing the offspring to see if they have inherited the desired characteristics, and if not, starting all over again.
遺傳標記物的存在能夠使植物育種家在細胞階段就開始進行選種，所用的方法包括尋找相應的基因以及在雜交早期進行檢查看看想要的基因是否遺傳到子代植物，這樣就不需要經過復雜的傳統育種過程：雜交授粉種植子代觀察子代是否獲得想要的性狀如果子代沒有攜帶想要的性狀，再從頭開始
