[Magnetic liquid influence upon some plant species of pharmaceutical interest]. / Influenta lichidelor magnetice asupra unor specii de plante de interes farmaceutic.

It was accomplished a study on the influence of a petroleum magnetic liquid upon two plant species of pharmaceutical interest: Papaver somniferum L. and Chelidonium majus L. Experimental observation aimed: callus accumulation, seed germination, mitotic index and fluorescence of the photosynthesis pigments. The plant samples were taken from in vitro cultures obtained from different explant types while the magnetic liquid was added in the culture media in low concentrations (ml/l). The germination test showed a positive influence of the magnetic liquid, the cell division test revealed an increased mitotic index, callus accumulation rate is enhanced while the fluorescence spectra showed maxima shift for the samples in comparison to the controls.

[Cytogenetic changes induced by low-intensity microwaves in the species Triticum aestivum]. / Modificari citogenetice induse de microunde de mica intensitate la specia Triticum aestivum.

Seeds of Triticum aestivum having an uniform genophond have been exposed to a microwave flow, with a frequency of 9.75 GHz and a low intensity. The effects of microwaves at various doses on mitotic activity have been followed. Our results show that as compared to the controls different types of chromosomal aberrations appeared: delayed chromosomes, micronuclei, interchromosomal bridges, chromosomal fragments.
