“…Aladjadjiyan (2010) also ascertained that root and shoot lengths were increased in magnetically treated seeds as compared to untreated seeds. Similarly, Vashisth and Nagarajan (2008) reported that magnetic field application significantly enhanced seed performance in terms of speed of germination, root and shoot length and seedling dry mass compared to unexposed control. Magnetic treatments are assumed to enhance seed vigour by influencing the biochemical processes that involve free radicals, and by stimulating the activity of proteins and enzymes (Kurinobu and Okazaki, 1995).…”

A b s t r a c t. The effects of magnetic field treatments of French marigold seeds on germination, early seedling growth and biochemical changes of seedlings were studied under controlled conditions. For this purpose, seeds were exposed to five different magnetic seed treatments for 3 min each. Most of seed treatments resulted in improved germination speed and spread, root and shoot length, seed soluble sugars and a-amylase activity. Magnetic seed treatment with 100 mT maximally improved germination, seedling vigour and starch metabolism as compared to control and other seed treatments. In emergence experiment, higher emergence percentage (4-fold), emergence index (5-fold) and vigorous seedling growth were obtained in seeds treated with 100 mT. Overall, the enhancement of marigold seeds by magnetic seed treatment with 100 mT could be related to enhanced starch metabolism. The results suggest that magnetic field treatments of French marigold seeds have the potential to enhance germination, early growth and biochemical parameters of seedlings.K e y w o r d s: marigold, seed, stimulation, magnetic field INTRODUCTIONMarigold is grown as an ornamental crop for loose flowers and as bedding plant in landscape. French marigold (Tagetes patula L.) is ideal for rockeries, edging, hanging baskets and window boxes. Both leaves and flowers are equally important from the medicinal point of view. Marigold petals are commercially valuable as a natural source of xanthophylls, pigments used primarily in poultry industry to intensify yellow colour of egg yolk. The essential oil present in different species of Tagetes is largely used in compounding of high-grade perfumes (Kaul et al., 2000). Crop stand establishment is always an important consideration in commercial field production. Similarly, rapid and uniform seedling emergence is the demand of every farmer as it is the foundation on which stand establishment is based and potential yield is determined. But, the emergence and stand establishment of marigold seeds are often slow and extremely erratic, particularly under hot or cool field conditions (Afzal et al., 2009). Currently, direct seeding is also popular among the vegetable and flower farming community in the world. However, it often results in uneven germination, slow emergence and poor stand establishment, but is less expensive initially and widely used in field operations. One of the greatest problems for marigold production is poor plant stand establishment. Magnetic seed pretreatments have been used successfully to improve germination rate and crop establishment, boost growth, development and ultimately yield of many horticultural and agronomic crops (Aladjadjiyan, 2010;Moon and Chung, 2000;Pietruszewski and Kania, 2010). Magnetic field pretreatment not only increased seed germination rate, seedling growth and yield (Balouchi and Sanavy, 2009) but also reduced the attack of pathogenic diseases (De Souza et al., 2006;Yinan et al., 2005). The beneficial effect of magnetic seed stimulation has been associated with various...

“…Seeds were exposed in batches to static magnetic fields ranging in intervals of 50 mT of from 0 to 250 mT for 1-4 h in steps of 1 hour for all fields. Best results were obtained from exposures of 50 mT for 2 h, 100 mT for 1 h and 150 mT for 2 h (Vashisth et al 2008). Accelerated germination after magnetic stimulation of wheat seeds was observed working with 30, 45 and 60 mT magnetic field strengths (Pietruszewski et al 2010).…”

“…Our results are in accordance with various researchers, which have been reported for verities of crops. Florez et al (2007), Vashista andNagarajan (2008, 2010) noted a considerable enhancement in germination characteristics such as seedling vigor, shoot and root growth in maize, chickpea and sunflower seeds when treated magnetically.

A b s t r a c t. The pea seeds were exposed to full-wave rectified sinusoidal magnetic fields. The effects of electromagnetic treatment on seedling growth and chlorophyll contents and have been investigated. Seed were sown after magnetic field treatment according to ISTA under controlled laboratory conditions. The magnetic filed treatment of seeds increased the growth significantly (P<0.05), while the increment in contents of chlorophyll have been found non significant (P<0.05). The shoot length, root length, root dry mass, shoot dry mass, fresh root mass and fresh shoot mass increased up to 140.5, 218.2, and 104, 263.6, 74.5, 91.3%, respectively. The result suggested that magnetic field could be used to enhance the growth in pea plant.K e y w o r d s:
