Abstract
The experiment was conducted at the nursery of the College of Agriculture, Kufa University, Al Najaf Province , during the growing season 2011 - 2012 to study the effect of spraying nutritional solution Foliartal and Licorice root extract Glycyrriza glabra L on growth and flowering parameters of carnation plant Dianthus caryophyllus L. The experiment was adopting Randomized Complete Block Design (R.C.B.D) in three replicates with tow factors; first factor implementing three concentration of nutritional solution Foliartal (0 , 1 and 2 Mg.L-1) and the second factor three concentration of Licorice root extract ( 0 , 2 and 4 Mg.L-1) and the interaction between the treatments. The mean were analyzed using L.S.D under probability level 0.05. The results showed that spraying nutritional solution Foliartal at concentration 2 Mg.L-1 or Licorice at concentration 4 Mg.L-1 improved vegetative and flowering parameters which increased significantly the following; plant height , number of leaves, shoot dry weight, leaf total chlorophyll an carbohydrates content , length of the longest root , root dry weight , number of flower and petals , diameter of flower and flower stalks and flower dry weight compared to the control treatment (sprayed with distilled water) which gave least values.. The interaction results showed that spraying with nutritional solution Foliartal at concentration 2 Mg. L-1 and Licorice roots extract at concentration 4 Mg. L -1 had a significant increase in all studied growth parameters; plant height, number of leaves , shoot dry weight, leaves total chlorophyll and carbohydrates content , length of the longest roots, root dry weight , number of flowers and petals , diameter of flower and flower stalk and flower dry weight . The number of flowers and petals , diameter of flower and flower stalk and flower dry weight gave 9.33 flower. plant -1 and 12.67 petals.Flower -1, 4.27 cm and 0.40 cm and 4.13 gm compared with the control treatment (sprayed with distilled water) which gave 5.00 flower.plant -1 and 8.00 petals. Flower -1, 1.33 cm and 0.12 cm and 1.20 gm respectively.
