By using primers designated for lacz gene, pcr result suggested an integration of lacz into u. pinnatifida genome. nine reagents including penicillin g, kanamycin, g418, teicoplanin, zeocin, chloramphinicol, hygromycin, basta and methotrexate were tested as selective reagents for selection of transgenic sporophytes. the results showed that young sporophytes of u. pinnatifida were sensitive to chloramphinicol and hygromycin and very sensitive to basta which suggest the potential of using the resistance genes as selectable markers

結果表明,離子型凝膠比非離子型凝膠具有更好的防附著能力,其中聚氯化三甲基3 -丙烯酰胺丙基胺凝膠和聚丙烯酸凝膠表面海帶孢子的萌發率均為0 ,適合作為防附著材料。Several vegetative clones of male or female gametophytes of u. pinnatifida has been induced and parthenogenesis of female gametophytes has been observed. 90 % of the gametophytes can grow into young sporophytes one month after fertilization. no staining background of either lacz or gus was found in different tissues of u. pinnatifida
進行裙帶菜配子體孤雌生殖、孤雄生殖和雌雄受精的再生途徑實驗,結果沒有得到孤雄生殖的裙帶菜,孤雌生殖的效率低、時間長且發育不正常,雌雄受精的再生途徑一個月左右90 %以上的雌配子體都正常萌發成幼孢子體。When every s. guan carried about 1 10 ^ 7 spores of coccoid beauveria bassiana, and touched the 4 5 - instar of m. alternatus larva with 1 : 1, 1 : 2 and 1 : 3, the ratios of m. alternatus amounts to s. guan amounts, the parastizing infecting death rates were 55 %, 75 %, and 100 % respectively ; s. guan carried coccoid beauveria bassiana to control m. alternatus in the wood section, and the rate was 87. 13 %
每隻管氏腫腿蜂攜帶球孢白僵菌約1 10 ^ 7個孢子時,對4 5齡松墨天牛幼蟲按蟲蜂比1 : 1 、 1 : 2和1 : 3接蜂,寄生感染死亡率分別為55 % 、 75 %和100 % ;管氏腫腿蜂攜帶球孢白僵菌防治木段內的松墨天牛幼蟲寄生感染死亡率為87 . 13 % 。After the acet is vaporized, the active substance in water is gotten. and which is vaporized at low temperature. then the crude active substance is purified by column chromatography on sephadex g - 75. after a series of purifications again, we could get some white powder at last. though the active substance is diluted to50 g / ml, the activity is still checkeded - up through phyto phtnora casicileon. the purified active substance is insensitive to heat, resistant to chloroform 、 ethanol and the orhers. in addition, the active substance is sensitive to high ph ( 10 ~ 14 ), but it is not sensitive to low ph ( 1 ~ 5 ). furthermre, when the ph is made to low again, the activity of it ' s comes back
