we are working on salinity tolerance of some crop plants,including certain fruit trees such as date palm and citrus.

This study conducted in Omman
The date palm has profitable and nutritional value. It has a lowest water demand, tolerates ruthless weather, and tolerates high levels of salinity (Diallo, 2005)
Date palm is itself a highly salt tolerant crop. As observed by many of the scientist, the yield loss may be upto 50 % if the water quality is poor, although majority of the varieties yield good (average 100 kg even in saline water- 4000 TDS level @ Date Palm Research Station, Mundra, India). The problem with tissue cultured plants are only in the initial month of planting. If the survives initially, it will not be affected much by higher level of salinity.
To maintain normal metabolism demand needs more energy Gale and Zeroni, 1985), which may result in reduction in growth and yield (Subbarao and Johansen, 2010).
Dakheel (2005) reported that Increasing soil salinity gave a negative impact on the date palm
I think it may depends on the type of salt, and you may need to analyze the soil.
Dear Muayed Fadhil Abbas
I think that there was no study about tolerance of date palm trees producing by tissue culture at the fruiting stage to salinity ...
Thank you
Date Palm is a drought and salt tolerance, such tolerance presumably due to deep roots and plant toughness which enable plants to occupy larger soil volume besides toughness that make plants substantially less response to environment. It seems that date palm more capable in sequestering salts away from protoplasmic enzymes, where no enzyme yet has been found to endure salt negative effects. Additionally, no salt secreting apparatus is observed in date palm
