Effect Of Magnetic Field On Seed Germination And Transplant Growth Of Tomato

 

Abou El-Yazied1, A.; Shalaby2, O. A.; A.M. El-Gizawy1; S.M. khalf2 and A. El-Satar3

 

ABSTRACT: Tomato (Lycopersicon esculentum Mill) cv. Castlrock seeds were exposed to different magnetic strengths (0.1, 0.15 and 0.2 Tesla) for periods of 1, 5, 10 and 15 minutes and the treated seeds were germinated under distilled water or in saline concentration levels of 2500, 5000 and 7500 ppm. The results indicated that the magnetic field treatments led to a significant increase in the germination percentage, reduced the time needed for germination and improved seed germination under saline conditions. The best results were found by magnetic seed treatment with 0.1 Tesla for 15 min. On the contrary, high salinity concentrations decreased the germination of seeds, as for the saline concentration of the 2500 ppm activated the seed germination. In the nursery experiment, applying the optimal magnetic seed treatment (0.1 T for 15 min) and/or irrigation with magnetized water gave significant increases in transplant stem length, stem diameter, leaf area and fresh and dry weight than those in the control treatment which grew by untreated seeds and irrigated by ordinary (untreated water) water.

ABSTRACT: Lepidium sativum (Fam. Brassicaceae), a popular vegetable producing plant of low reaches of Kumaun Himalaya, is an annual herb and its leaves are used as a Traditional Medicines to cure abdominal pains, asthma and lowering blood pressure. An aqueous Extract derived from the leaves of the plant, highly food supplement for human,has previously been screened for various biological activities, hypotensive, antimicrobial, bronchiodilator, hypoglycemic and allelopathic. n-Butanol fraction of aqueous-methanolic extract, a highly flavonoid enriched and antioxidative active against DPPH and ABTS free radicals, afforded three flavonol glycosides, quercetin-3-O-β-glucosyl (1 à 2)– glucopyranoside- 7-0- glucopyranoside, kaempferol-3–O– β- glucosyl (1 à 2)- glucopyranoside – 7 – O – β – glucopyransoide and isorhamnetin – 3 – O – sophoroside -7 – O – β – D – glucopyransoide . The antioxideant activity of quercetin – 3, 7 – di-O-glycoside was found higher compared to the corresponding 3,7–di-o-glycosides of kaempferol and isorhamnetin.

Abstract: Vocational education and training is very cardinal to any economic development of a country. Training in general has potential benefits which accrue to the individual, organization and the nation in general. To the individual training enhances their future earning potentials career progression ad employability. To achieve the above, the paper argues that the individual or groups will need skills to perform competently. With skill the individual can determine their own destiny. Because of the importance of skills to the individual, it is important that every individual access training to contribute to development. Currently Nigeria, not everybody is able to access training with the rise in population growth and economy going down, governments are unable to offer social amenities. Even schools and colleges cannot match the rising population and as a result fewer and fewer people are accessing training. The paper therefore focused on the contribution of a revitalized technical and vocational education and training to improve the economic status of the country and welfare of the people, trigger entrepreneurship which would eventually lead to job creation. The paper concludes that to solve the problem of widespread poverty, unemployment and national food deficit, priority should be giving to revitalized-technical and vocational education.
