Response of some Citrus Rootstocks to irrigation with different salt concentrations water

Abstract

 The experiments of this research were conducted on the seeds and plants resulting from these seeds obtained from three citrus origins, namely: pomelo, Citrang Carrizo, and Systromelo 4475, where the seeds were taken from the fruits trees planted at the citrus Research Center in Tartous (2010) to test their ability to Give the embryos. The resulting plants for irrigation with water of different salt concentrations (30, 60, 90) of NaCl in addition to the control and selection of the most tolerant origins.

The results showed that the Carizo Citrange outer formed over the rest of the assets in terms of germination percentage (97%), As for the phenomenon of multiple embryos at the origions, all the seeds of the Rootstocks Pomelo gave one embryo, whereas, Carizo-Citrange surpassed Cetromelo by the number of embryos resulting from a single seed, As for the total increase in plant length since the beginning of the experiment. The results showed the superiority of Carizo Citrange over the other two Rootstocks, followed by the Cetromelo, while the Pomelo came in the last, As for the effect of the reaction on the vegetative growth characteristics of the plant (number of branches, stem diameter, leaf area wet, weight of leaves, dry weight of leaves, dry weight of vegetative mass), CarizoCitrange straw outer formed the rest of the assets when increasing the salt concentration in irrigation water, which was less affected by the high salt concentration in the soil.
