【摘要】：本文以海帶(Saccharina japonica)配子體、配子體克隆及幼孢子體為實(shí)驗(yàn)材料,研究了不同發(fā)育時(shí)期的海帶對(duì)草甘膦、草丁膦、氯霉素的敏感性,經(jīng)SPSS軟件計(jì)算出一定時(shí)間內(nèi)3種選擇試劑對(duì)不同發(fā)育時(shí)期海帶的半致死劑量(LD50)。結(jié)果表明:海帶配子體及配子體克隆對(duì)草甘膦和草丁膦極為敏感,對(duì)氯霉素較為敏感。4d時(shí),草甘膦和草丁膦對(duì)海帶配子體的LD50分別為8.19μg/mL和19.27μg/mL,對(duì)海帶配子體克隆的LD50分別為73.69μg/mL和39.08μg/mL;而氯霉素對(duì)海帶配子體及配子體克隆4天的LD50則高達(dá)742.00μg/mL和701.51μg/mL。海帶幼孢子體僅對(duì)草甘膦極為敏感,4d的LD50為40.93μg/mL;對(duì)草丁膦和氯霉素較為敏感,4d的LD50分別為214.51μg/mL和907.86μg/mL。該結(jié)果說明草甘膦和草丁膦適合作為以海帶配子體和配子體克隆為實(shí)驗(yàn)材料的基因工程選擇試劑,草甘膦則更適合以海帶幼孢子體為實(shí)驗(yàn)材料的基因工程選擇試劑。
[Abstract]:In this paper, the sensitivity of Laminaria japonica to glyphosate, butylphosphine and chloramphenicol at different developmental stages was studied by using gametophyte, gametophyte cloning and juvenile sporophyte as experimental materials. The results showed that the gametophyte and gametophyte clones of Laminaria japonica were very sensitive to glyphosate and glyphosate and were sensitive to chloramphenicol for 4 d. The LD50 of glyphosate and glyphosate to gametophyte of Laminaria japonica were 8.19 渭 g / mL and 19.27 渭 g / mL, respectively. The LD50 of gametophyte clone of Laminaria japonica were 73.69 渭 g / mL and 39.08 渭 g / mL, respectively. The LD50 of gametophyte and gametophyte cloned by chloramphenicol for 4 days was 742.00 渭 g / mL and 701.51 渭 g / mL, respectively. The LD50 for 4 days was 40.93 渭 g / mL for glyphosate and 214.51 渭 g / mL for glyphosate and 907.86 渭 g / mL for chloramphenicol for 4 days, respectively. The results showed that glyphosate and glyphosate were suitable for gene engineering selection with gametophyte and gametophyte clones of Laminaria japonica. Glyphosate is more suitable for genetic engineering of laminaria japonica.
