Abstract

The present research aimed to investigate the effect of different concentrations of cadmium and ascorbic acid on some characteristics of germination and early growth of balangu (Lallemantia royleana (Benth.)) and basil (Ocimum basilicom L.). This experiment was as a factorial layout based on a completely randomized design with two factors and three repetitions. The experimental treatments included four levels of cadmium sulfate 0, 20, 40, and 60 mg l^-1and three levels of ascorbic acid 0, 200, and 400 mg l^-1. The results showed that the increase in the concentration of cadmium caused a decrease in the length of the radicle, the number of normal seedlings, germination percentage, seed germination, seedling weight, and of course, an increase in the weight of the balangu plumule. In basil, root length decreased by 29.1, 18.6, and 35.2% in treatments with 20, 40, and 60 mg l^-1of Cd compared to the control. In other words, radicle length significantly declined with rising Cd concentration from 0 to 60 mg l^-1. Ascorbic acid improved the characteristics of the length of the radicle, germination rate, and percentage in balangu. In addition, ascorbic acid mitigated the negative effects of cadmium and increased the number of normal balangu seedlings, especially at concentrations of 40 and 60 mg l^-1of cadmium. Basil root length increased with 200 and 400 mg l^-1of ascorbic acid application. In general, it seems that seed pretreatment with ascorbic acid could be used as a strategy to moderate the negative effects of Cd stress.
