Mustard Seedling

The temporal pattern of control by phytochrome of the enzyme lipoxygenase (EC 1.13.1.13) in the mustard seedling (Sinapis alba L.) is described. The biosynthetic system which produces lipoxygenase does not respond to phytochrome (Pfr) up to 33.25 h after sowing (25°C). By this time the control by Pfr comes suddenly and fully into play. At 48 h after sowing the system escapes from the control by Pfr. Neither the beginning nor the end of the period of control is influenced by phytochrome. Interpretation of the data requires a double action control mechanism. It is argued that such a mechanism is necessarily a characteristic of development in multicellular organism.

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.
