Relations Between Water Stress, Selenium and Brassinolide Hormone on Some Vegetative Parameters and Elements Content of Coriander Plant Coriandrum sativum L.

Abstract

The aim of study was to assess water stress for 2,8,14 days and spraying selenium at0,10,20 mg/L-1 and brassinolide 0,1,2 mg/L-1 on vegetative growth and macro elementscontent (NPK) for Coriander (Coriandrum astivum L.) plant, The experiment wasperformed with Factorial Randomized Block Design (R.B.C.D) with three replicates .Theresults were summarized as follows:1- The period of sever water stress for 14 days was passive effect on growth parameters.2- The means of elements content NPK content was increased at moderate stress for 8days.3- The effect of selenium and brassinolide was positively to increase studied parameters.4- Selenium and Brassinolide decreased water stress also the triple interaction betweenthe severe stress at 14 days and the spraying the selenium and hormone was positive todecrease effect of severe stress
