Résumé partiel
The present study was carried out at Agronomy Department, Faculty of Agriculture, Tanta University. The field experiment was conducted at the experimental Farm, Sakha Agricultural Research Station, A. R. C., Kafr El- Sheikh Governorate, Egypt, during 2014/2015 and 2015/2016 seasons to study the Reponses of twelve barley genotypes under normal and stress irrigation. The aims of the present work, was to examine some barley genotypes under normal and drought condition using some growth and yield measurement to determine the most tolerance one could be used to obtained high biological and grain yield under water stress conditions. Plant materials : Twelve barely genotypes i.e. Giza 117, Giza 118, Giza 121, Giza 123, Giza 124, Giza 125, Giza 126, Giza 2000, Giza 132, Giza 133, Giza 127 and Giza 128 were chosen for the study based on their reputed differences in yield performance under normal and stress conditions. The obtained results could be summarized as follows : 4.1. Analysis of variances : All the studied characters were significantly affected by water stress in both growing seasons and their combined analysis, except for total chlorophyll content in both seasons, 1000-grain weight in both seasons and combined analysis, maturity date and harvest index in the first season. The results indicated that, the normal irrigation exceed the stress irrigation for all studied traits in both seasons and their combined analysis, except total chlorophyll content and harvest index in both seasons and their combined analysis and 1000-grain weight in the first season. B-Mean performances : 1. Total chlorophyll content : It could be clear that Giza 127 seemed to be the most stable one among all tested genotypes where, it gave the highest values of Total chlorophyll under normal condition both seasons and the combined data respectively. These values insignificant increased under stress condition in both seasons and the combined data respectively. On the other side, the behavior of all others genotypes differed from environment to another and ranked differently from stress to normal irrigation. Also, the results showed that Giza 2000 genotypes seemed to be the most sensitive one to water stress among all tested genotypes in this traits in both seasons and the combined data. 2. Days to maturity : The results showed that that Giza 121 and Giza 132 were the earliest among all tested genotypes under normal irrigation in both season and the combined data, While, Giza 2000, Giza 132 and Giza 133 were the earliest among all tested genotypes under stress irrigation in both season and the combined data. On the other side, Giza 125 under normal and stress irrigation was the latest one among all tested genotypes in both season and the combined data.
