To provide the using information of disinfectors dose in the tobacco float seedling system,the efficacies of 90% lethal dose(EC90) of 10 disinfectors were examined by carrier germicidal test on breeding substrates,including polystyrene foam trays,polyvinyl chloride plastic film and stainless blade which were inoculated with Ralstonia solanacearum.
在聚苯乙烯泡沫苗盘、聚氯乙烯塑料池膜和不锈钢刀片表面,8种消毒剂的90%致死剂量(EC90)差异大,30%有效氯漂白粉为96。
At same time, we also knew the LD100 of konjac is 3KR and LD50 is 1.
同时,初步得到照射花魔芋半致死剂量LD50为1。

Toxicity of emamectin to larvae of the diamondback moth, Plutella xylostella, at different temperatures was surveyed, and the effects on survivors of parent generation treated with sub-lethal dosage of the insecticide at 25℃ were studied with life table method.
研究了不同温度下埃玛菌素 (emamectin)对小菜蛾Plutellaxylostella幼虫的毒力 ,并用生命表法研究了 2 5℃下埃玛菌素亚致死剂量 (LC30 )处理小菜蛾 3龄初期幼虫后对其子代的影响。
to 10 antibiotics: gentamicin,neomycin, ampicillin,kanamycin,cephalothin,streptomycin,G418,hygromycin Zeocin and chloramphenicol were investigated.
利用统计学的方法和原理,确定了G418、潮霉素、Zeocin和氯霉素在海水培养基和淡化10倍的培养基中对小球藻的半致死剂量和95%可信限。
Moreover,the higher dose,the higher death rate,and the Half Lethal Dosage(LD50)for the seedlings of 41 days was 150 Gy.
随着剂量的增高,死亡率增高,组培苗生长41d时的半致死剂量(LD50)为150Gy。
The result showed that the stronger was radicalization,the larger was restrained degree;the sensitivity of different varieties were different; the LD50 of adventitious buds was 30-40GY, the LD50 of the calli was 10-20GY.
5-6 5Gy剂量辐射处理红掌6个品种的不定芽和愈伤组织材料,并进行组培试验,结果表明辐射愈强,参试材料受抑制程度愈大;不同红掌品种对辐射的敏感性不同;初步看出60Co对不定芽半致死剂量为30-40Gy,对愈伤组织半致死剂量为10-20Gy。
The Lethal Dose50 test( LD50) may also be replaced.
药剂致死剂量50(D50)验也可以被代替。
