The development of extractable peroxidase activity in the mustard seedling is controlled by phytochrome (Pfr; operationally: Continuous far-red light) in an organ specific manner (enhancement in the cotyledons and taproot, inhibition in the hypocotyl; Tables I, II). Detailed kinetics of peroxidase accumulation in the cotyledons (Figs. 2, 3) reveal the existance of a two-step induction mechanism: 1. Formation of a stable transmitter during a period of competence to Pfr (“determination phase“), and 2. development of peroxidase activity mediated by the transmitter during a later period of competence to the transmitter (“realization phase“). These two periods of seedling development are completely separated in time.

Illegal dumps and landfills with disposed of tires are a fact of today, which should not be neglected as they represent a great ecological burden for the environment, affect the surrounding nature and disturb the landscape. This research was focused on testing the phytotoxicity of aqueous leachates from the fractions of tires in two sets of experiments—to simulate laboratory conditions (tire leaching in distilled water) and natural conditions (tire leaching in water from a recipient) using the Phytotoxkit testing kit (kit for the establishment of inhibition/stimulation effect on the root development) and the watercress test of phytotoxicity (biological method for the assessment of leachate phytotoxicity). Plants whose seeds were selected for the test were watercress (Lepidium sativum L.) and white mustard (Sinapis alba L.). The aqueous leachate was tested for 38 weeks. During the experiment, physical and chemical parameters were measured at intervals of 14 days by the testing instrument HACH TEST KIT: electric conductivity (EC), amount of dissolved oxygen (LDO) and pH. Results of root growth inhibition (IR) on the seeds of Lepidium sativum L. and Sinapis alba L. exhibited values ranging from 11.73% to 47.74% in the tested samples. Results of germination index (GI) on the seeds of Lepidium sativum L. exhibited values below 66% in the tested samples, which indicated the leachate phytotoxicity. In spite of the fact that similar studies are tackling the acute toxicity of leachates from tires (particularly to algae, embryos and animals), this research brings complementary information in testing the acute phytotoxicity of tire leachates to higher plants.
