It is summarized that the seedling's tolerance of half lethal salt concentration, the seed vigour index, and the seed nitrogen content could be regarded as the physiological index for assessing the level of the seed salt tolerance and whether it be selected for breeding.

The half lethal concentration of 48? h-LC_ ( 50) of 21 nitrobenzenes to Daphnia carinata was determined by use of the standard test method, and the range of toxicity was from 3.49 for nitrobenzene to 5.40 for 1,4-dinitrobenzene.

The extract had higher toxic killing effect on Euproctis bipunctapex larvae. However, the effect was lower. The median lethal concentration ( LC_ ( 50)) for the larvae treated for 72 h was ( 0.03227%).

雷公藤提取物对乌桕毒蛾幼虫具有较高的毒杀作用，但表现比较缓慢，处理72h后的死亡中浓度LC50为0.03227%。

The grades were designed by equal space between logarithm, and the median lethal concentration was computed by Linear Regression.

浓度梯度按等对数间距设置，半致死浓度采用直线内插法进行计算。

Median lethal concentration to human embryo lung fibroblastic cell is about 41.3 μ g/ ml.

引起半数人胚肺成纤维细胞生长抑制的浓度为41.3μg/ml。

The median lethal concentration data is reliable for future biological observation.

为今后的生物监测提供可靠的半致死浓度的数据。
