Effect of Magnetic Field on Growth and Development Parameters of Rudbeckia hirta L. Seed in Dry and Humid Conditions
The magnetic field (MF) is considered as a biophysical treatment to change the growth and development parameters. Current research was carried out to evaluate the effect of different intensities of MF (0, 45, 60, 70 and 75 mT) on seed germination and some morphologic and physiologic parameters of Rudbeckia hirta L. in dry and humid conditions for 30 min. Results showed that the MF trea...

متن کاملBehavioral effects of Euphorbia hirta L.: sedative and anxiolytic properties.
Lyophilised aqueous extract of Euphorbia hirta L. (Euphorbiaceae) has been evaluated for behavioral effects in mice. The extract did not induce any toxic effect when it was administered i.p. and orally. Sedative properties could be confirmed with high doses (100 mg of dried plant/kg, and more), by a decrease of behavioral parameters measured in non-familiar environment tests (activitest and sta...
