| Abstract The study was conducted to determine the effect of the exposure Period to the North or the South Pole of Magnetic field with extensity 200 mili tesla on growth and multiplication of Gardenia explants which cultured on MS medium. The explant exposed to period (0 , 10 , 20 , 30 , 40) day during multiplication stage and (0 , 2 , 10 , 14) day in rooting stage. The results shows that after 8 weeks of multiplication stage the treatment of 20 day exposure to the south magnetic pole produced a significant increase in number of shoots formation (10.2 shoot/explant), shoot length (13.4 cm) and explant fresh weight (1.26 g/explant) as compared with control treatment which gave 8.8 shoots/explant , 1.9 cm of shoot length and 0.85 g/explant of fresh weight. On the other hand the treatment of exposed to the north pole resulted in a significantly increase in no. of shoot (11.3) shoots in 10 day exposure and shoot length was 5.0 cm in 20 day exposure comparing with the control treatment which produce 8.8 shoots/ explant and 4.0 cm of shoot length. the study revealed that the explant exposed to the south pole for 2 days decreased of the necessary period to obtain 100 % of rooting percentage to half (2 weeks) as compared with control treatment (4 weeks), in addition to shoots expose for 6 and 10 days to the south magnetic pole which exhibited a significantly increase in root length (4.6 cm) for both treatments as compared with 3.2 cm in the control. However the exposure of shoots to the north magnetic pole field for 2 and 6 days affected significantly in root length (5.1 cm) and chlorophyll density (54.8) respectively, comparing with control treatment which gave root length 3.2 and 49.7 respectively. | ||
