Mineral ion concentration in tissues that reduces the dry weight of tissues by about 10% is considered asA. critical concentrationB. toxic concentrationC. optimum concentrationD. beneficial concentration |
Answer» Correct Answer - B In higher doses, micronutrients, become toxic. Mineral ion concentration in the tissues which reduces dry weight of tissues by 10% is called toxic concentration. Critical toxic concentration. Critical toxic concentration is different for different micronutrients as well as different plants. for example `Mn^(2+)` is toxic beyond 600 `mu` `g^(-1)` for soybeam and beyond `5300mug` `g^(-1)` for sunflower toxic effects may be due to an excess of the micronutrient or its interference in the absorption and functioning of other nutrients. |
