S. regeneration system of mustard hypocotyls and cotyledons of 4 days and leaves of 25 days were used as transformation materials, and ms as basic medium supplying different ba ^ naa and kt concentration, we got the optimum explant adventitious bud inducing medium ( ms + 6 - ba3. 0mg / l + naa0. 2 mg / l ). among the three kinds of mustard explants. the cotyledons showed the highest adventitious bud regeneration capacity. and the regeneration capacity of leaf explantswas weaker. and the weakest of hypocotyls
芥菜高頻再生體系的建立以4天左右的葉用和莖用芥菜子葉、下胚軸和25天苗齡的芥菜無菌苗的葉片為外植體，以ms為基本培養基，通過加入不同濃度和不同組合的ba 、 naa 、 kt ，篩選到了外植體不定芽分化的最適培養基（ ms + ba3 . 0mg / l + naa0 . 1mg / l ）及生根的最適培養基（ ms + naa0 . 2mg / l ） 。6. transformation system of mustard a serials of kanamycin concentration was added to optimum medium to test the explants resistance capacity of two kinds of mustard. the transformation procedures described were derived from numerous regeneration and trasformation designed to test factors that might affect shoot regeneration, which including length of co - cultivation. those producing the best result parameters were described as below : after the mustard explants were precultured on regeneration medium for 2 days. they were inoculated with agrobacterium for 20 minutes. inoculated explants were co - cultivated for 4 days and in shadow at first 2 days. then transferred to the same medium plus 30 mg / l kanamycin and 500mg / l garb. all of them were transferred to fresh medium every 2 weeks. the kan - resistant plants were regenerated
芥菜外植體高頻遺傳轉化體系的建立在最適培養基上試驗了兩類芥菜的三種外植體對卡那黴素的敏感性、預培養天數、浸菌時間等因素的影響，建立了芥菜高頻轉基因再生體系：取生長4天的芥菜子葉、下胚軸和25天的葉片在分化培養基上（ ms + ba3 . 0mg / l + naa0 . 1mg / l ）預培養2 - 3天後，投入農桿菌菌液中浸染20分鐘，在分化培養基上暗培養2天，正常條件下培養2天後，轉入抗性培養基（ ms ba3The former one is a product of the pressure pulsation resulting from the fan blade periodically cutting the air, with the blade passing frequency as its base frequency and accompanied by higher harmonics. the wide - band turbulent noise is formed when the rotating fan forces the surrounding air to produce turbulent throw - outs and results in gas thickening and thinning processes
旋轉噪聲是由於風扇的葉片周期性地切割空氣，引起空氣的壓力脈動產生的，以葉片通過頻率為基頻，並伴有高次諧波。湍流噪聲是由於風扇運動導致的周圍空氣發生湍流脫體，使空氣發生擾動，形成氣體的壓縮與稀疏過程而形成的，是一個寬頻帶噪聲。The result of study on the factors affecting the transformation frequency showed : the leaf disc was pre - cultured for 2 days, infected for 20 minutes, co - cultivated with agrobacterium eha105 for 2 days, which could improve regeneration efficiency. the highest regeneration efficiency was 13. 3 % in this experiment
實驗結果表明：葉片預培養2d ，農桿菌浸染20min ，與農桿菌共培養2d時，篩選培養基上洋桔梗葉盤不定芽分化頻率最高，達13 . 3 。分享友人
