الملخص EN

An experiment was conducted at the nursery of Agriculture Faculty/ Kufa University during growing season 2012 – 2013 to study the effect of spraying extract of Schanginia aegyptiaca L.

and the numbers of spraying in growth parameters of Carination.

Experiment was adopted in Randomized Complete Block Design (R.C.B.D.) with three replicates in two factors First three concentration of Schnginia Extract i.e.( 0 , 5% and 10% ) and the second numbers of spraying (one, two and three) and their interaction .

Means were compared by using Least Significant Difference Test (L.S.D) at propriety 0.05.

Results showed that spraying of Schnginia Extract at concentration of 10% or two sprays increased significantly growth parameters (plant height, number of leaves, shoot dry weight, total content of chlorophyll and soluble carbohydrates, number of flowers and petals, diameter of flower, flower dry weight, vasa life of flower and flowering date compared with plant of control treatment which gave the least vales from the above characteristics.

Results revealed that spraying of Schnginia Extract at the concentration of 10% and two spraying increased significantly growth parameters of (plant height, number of leaves, shoot dry weight, total content of chlorophyll and soluble carbohydrates) and flowering parameters (numbers of flowers and petals, diameter of flower, flower dry weight and vasa life of flower) that reached 8.67 flower.Plant-1, 36.33 petals.Flower-1 and 7 days) compared with that plant of control treatment which gave the least values (4 flowers.plant-1 , 21.67 petals.

Flower-1 and 4 days), respectively.
