In this work the results of the evaluation of toxicity in the germination and root growth processes of Lactuca sativa (Lettuce) due to the use of saline compounds (NaCl, KCl and K2SO4) are presented. Tests have been carried out on two types of seed species of Black and Red Lactuca sativa. For the process, the three saline media were inoculated at the same concentration and the seeds were incubated for a period of 6 days. After this period the length of the roots, number of germinated seeds in each saline medium was evaluated. It was shown that salinity influences germination differently for red and black seeds with reference to the control culture medium.

Toxicidad producida por compuestos salinos en el proceso de gerinación de Lactuca sativa

在这项工作中，介绍了使用盐分化合物（NaCl、KCl 和 K2SO4）对莴苣（生菜）发芽和根生长过程中毒性的评估结果。已经对两种类型的黑色和红色莴苣种子物种进行了测试。对于该过程，三种盐水培养基以相同的浓度接种，并且将种子培养 6 天。在此期间之后，评估根的长度、在每种盐培养基中发芽的种子数。结果表明，相对于对照培养基，盐度对红色和黑色种子的萌发影响不同。
