Abstract Effect of depth ( 5,10 and 15cm) of planting Lilium (cv. Fangio) bulbs . The present work was carried out throughout two successive seasons (2011and 2012 .) Data indicated that planting with a layer of (5cm) soil on the top of the upright bulb gave the least height during the two seasons Meanwhile, the best height that resulted with the deeper planting (15cm ). The highest value of No. of leave / plant was due to using the deeper culture (15 cm) .The stem diameter was increased by increasing the planting depth significantly during both seasons. No. of flowers plant was increased by using (15 cm )soil on the top of upright bulb ; while ,the two treatments (10 and 15 cm ) gave the highest No. of flower especially in the second season . Significant increases in fresh and dry weights of flower (g) resulted from both (10 and 15 cm) when compared with (5 cm) treatment during both seasons. Marked influences in flower stalk fresh weight were obtained due to deeper culture Effect of soaking period of Lilium (cv.Fangio) bulbs in amino acid (Tyrosine) during the two seasons ( 2011and 2012).Prolonging soaking periods from 2 h. to 4 h . gave the tallest plants in both season The treatment of soaking periods the bulbs for 4 h .increased No. of leaves / plant significantly in both season while, prolonging the soaking time 8 h the bulbs in Tyrosine significant decrease No. of leaves / plant in the first Summary 72 season, while caused negligible increase during the second season . Also, prolonging soaking time in Tyrosine caused significant decrease in stem diameter. Negligible increase on no. of flowers affecting with the increasing soaking time of bulbs in solution of Tyrosine. Fresh and dry weights of flowers were affected significantly as recorded negligible decreased due to increasing of soaking period. N, P and K % were affected with increasing the soaking time in Tyrosine during the two seasons. The fungus Fusarium oxysporum f. sp. lily was found to be virulent pathogen on lily plants cv. Fangio (LA), since percentage of infection reached 85% on the plants grown in infested soil. Soil treating with each of all the treatments tested ,i. e. the fungicide Topsin M and the hot water extracts of Blue-gum leaves ,Rue herb and Thyme herb minimized percentages of infection by Fusarium disease significantly in lily plants (cv . Fangio) grown in infested soil . Topsin M, however, was significantly superior to the others in this respect and Thyme extract came the second in position. The treatments tested improved plant growth parameters (plant height ,No.of leaves and No.of florets ) significantly more than the control . The fungicide Topsin M, amongst the treatments, was the best in this respect, since the increment in these criteria of plant growth was significant if compared with the others in most cases. |
