The experiment was conducted at Kufa Technical Institute in AL-Najaf governorate during the growing season of 2003-2004. The purpose of the experiment was to find out the effect of three growth mediums and three levels of sea algae extract (Al-Garen) which used as spray on characteristics of flowering growth such as length and diameter of pedicel and total percentage of chlorophyll content in leaves. Flowers traits such as flower diameter, petals number and flowering date of Dianthus plants were also investigated.
The three growth medium which used in the experiment were:
1- A mixture of 2 parts of loam : 1 part of peat-moss.
2- A mixture of 3 parts of loam : 1 part of peat-moss.
3- A mixture of 4 parts of loam : 1 part of peat-moss.
The three concentrations of sea algae extract (Al-Garen) which had been sprayed at leaves were 0, 1 and 2 ml/L of water. Randomized Complete Block Design (RCBD) with three replications was used in a factorial arrangement with two factors. Growth medium was the first factor with three levels. The second factor was the concentration of algae extract with three levels. Analysis of variance was performed and Duncan Multiple Range Test (DMRT) was used to compare treatment means at probability level of 0.05.H.E. Dulaymy, J.A. Abbass and H.M. Al-Bakka.

For example, plants grown in growth medium of 2 parts of loam:1 part of peatmoss or sprayed by a (2 ml/L of water) of Al-Garen concentration had flower diameter of 5.21 and petal number of 31.08 and 28.41 compared with those raised in growth medium of 4 parts of loam:1 part of peatmoss or those plant which were not sprayed with Al-Garen, which produced the lowest flower diameter (4.17 cm and 3.61 cm) and the lowest number of petals (22.29 and 24.79), respectively.It was also found that the interaction of growth medium that consisted of (2 parts of loam:1 part of peatmoss) and sprayed with Al-Garen concentration of (2 ml/l of water) increased flowering yield and flower traits significantly for carnation (stem length, total chlorophyll in leaves, flower diameter and petals number).
