Effect of magnetic fields on seedling growth and cyto-morphogenesis inSinapis albaL.
Abstract The magnetic treatment presented in this study could be included among cultivation procedures aimed at a better utilisation of plant species. The treatment enhances seedling growth (expressed in fresh weight or in length of the hypocotyl) stimulates morphogenic events (premature differentiation of the reticulate xylem elements, increased wall thickness, reduction of the xylem diameter, increase of acid phosphatases) and renders the seedling batches more homogeneous. Our study demonstrates that exposure to weak (30 mT) magnetic fields for short periods (15, 30, 60 seconds) stimulates seedling growth.

Preliminary Results on the Effect of Magnetic Fields on Anther Culture and Pollen Germination of Citrus clementina Hort. ex Tan.
Exposure to electromagnetic fields seems to modify the biological behaviour of seeds, roots, pollen grains and buds of several plants. This procedure has been also suggested as a tool to improve the utilization of plant species (Firetto et al., 2000, 2001, Petruszewski S., 1996). Since the first haploid embryogenic calli production and plantlet regeneration by anther culture of C. clementina Hort. ex Tan. 'Nules' was reported (Germany et al., 1994), several studies have been carried out to improve both the frequency of microspore embryogenesis and the percentage of plantlet regeneration. To enlarge the number of respondent genotypes and to improve the induction rate (the frequency of pollen…
