| Abstract | ||
| This experiment was conducted in the lath house , Department of Horticulture, College of Agriculture, University of Baghdad to investigate the influence of wat salinity levels on the vegetative character of three olive seedlings Khudari ,Sorrani and Kassi,the highest of plant,the diameter of the stem ,number of branches,number of leaves, leaf area , fresh and dry weight of the vegetative part and the roots. two years old were planted in a containers with 18 kg growing media ,Three cvs. , Khudari , Sorrani and Kassi with five levels of water salinity 2,4,6,8 dSm-1 . The water salinity of 2 dSm-1 significantly increased the vegetative characters , while the levels 4,6,8 dSm-1 significantly decreased these characters ,there were significant differences between olive cvs.. The salinity level of 2 dSm-1 significant induced average height and diameter of main stem up to 91.13 cm and 1.48 cm for the characters respectively ,while the salinity levels of 8 dSm-1 gave the lowest valuesof 49.0 cmand 0.19 cm respectively in the khudari cv.Irrigating the Sorrani cv.with 2dSm-1water salinity significantly overcome the Khudari variety when irrigated with 8 dSm-1 level of salinity in the following characters the averages of the number of branches/plant ,number of leaves . leaf area , the fresh weight of the vegetative parts and roots increment of 1313.9%, 178.55% ,726.19%, 13.28% and 23.30% respectively. And conclude from the study attributes vegetative of olive varieties under study differ significantly in the degree of tolerance to salinity because of the variability in genotypes and possess different mechanisms to bear the stress of saline. On this basis, we recommend inour study to the growing class Sourani in soils affected by salinity because it is classified tolerant to salinity. | ||
