Response of Carnation Dianthus caryophullus L. to spraying extract of Schanginia aegyptiaca L. and numbers of sprays in some vegetative and flowering growth parameters

Abstract

An experiment was conducted at the nursery of Agriculture Faculty/ Kufa Universityduring growing season 2012 – 2013 to study the effect of spraying extract of Schanginiaaegyptiaca L. and the numbers of spraying in growth parameters of Carination.Experiment was adopted in Randomized Complete Block Design (R.C.B.D.) with threereplicates in two factors First three concentration of Schnginia Extract i.e.( 0 , 5% and10% ) 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 propriety0.05. Results showed that spraying of Schnginia Extract at concentration of 10% or twosprays increased significantly growth parameters (plant height, number of leaves, shootdry weight, total content of chlorophyll and soluble carbohydrates, number of flowers andpetals, diameter of flower, flower dry weight, vasa life of flower and flowering datecompared with plant of control treatment which gave the least vales from the abovecharacteristics. Results revealed that spraying of Schnginia Extract at the concentration of10% and two spraying increased significantly growth parameters of (plant height, numberof leaves, shoot dry weight, total content of chlorophyll and soluble carbohydrates) andflowering parameters (numbers of flowers and petals, diameter of flower, flower dryweight and vasa life of flower) that reached 8.67 flower.Plant-1, 36.33 petals.Flower-1 and7 days) compared with that plant of control treatment which gave the least values (4flowers.plant-1 , 21.67 petals. Flower-1 and 4 days), respectively.
