Abstract
The present study was carried out during the two successive
seasons of 2013 to 2015 in a private nursery at Kafr El Sheikh
Governorate, Egypt on Succary mango cultivar and four
polyemberyonic unknown mango genotypes grown in Ismailia and
Suez Governorates. The trees were 10-15 years old and grown
under high salinity stress. One tree from each region was selected
and labeled to be the source of seeds each season. Seeds were
freshly extracted from ripen fruits then sowed in polyethylene bags
during August. The seedling received the recommended
agricultural practices from august to April. At the first of May, the
seedlings were treated with different concentrations of sodium
chloride till the end of August. Data showed that the vegetative
growth (plant height, leaves number and area, stem thickness, roots
number, fresh weight and dry weight), total carbohydrates, total
chlorophyll, total nitrogen, phosphorus, potassium and calcium
significantly decreased as salinity concentration increased. On the
other hand, the amino acid proline, sodium and chloride contents
significantly increased with increasing salinity. Data indicated that
clone 3 is the best rootstock followed by succary cv., clone 2 and
clone 1 while clone 4 is the most sensitive to salinity.
