The performance of two pomegranate cultivars (Manfalouty and Nab El-Gamal) under two levels of plant spacing (2.5x2.5m) and (4x4m) at the newly reclaimed sandy soil was studied. Results revealed that, (2.5x2.5m) plant spacing recorded the highest significant values of tree height, yield/feedan, peel thickness and percentage of marketable fruits. In addition, it reduced percentage of disordered fruits (sun burned and cracked), while it affected negatively on (trunk girth, canopy volume, perfect flowers/tree, initial fruit set/tree, number of fruits/tree, yield/tree, fruit weight, total sugars and total soluble solids) which gave the highest values with (4x4m) treatment. Moreover, Manfalouty cultivar recorded the highest significant values in most characteristics compared to Nab El-Gamal.   It could be recommended that, under the same conditions of the present study, Manfalouty cultivar trees could be planted under the level of plant spacing  (2.5 x 2.5 m).}, keywords = {pomegranate,planting density,plant spacing,productivity,Fruit disorders,Manfalouty,Nab El-Gamal}, url = {https://ejoh.journals.ekb.eg/article_1213.html}, eprint = {https://ejoh.journals.ekb.eg/article_1213_942f62dd4bf5ba37a1f18becec50c6ab.pdf} } @article { author = {}, title = {Effect of Calcium and Boron Foliar Spray on Fruit Quality and Leaf Nutritional Status of "Kelsey" Plum Trees}, journal = {Egyptian Journal of Horticulture}, volume = {40}, number = {1}, pages = {19-36}, year = {2013}, publisher = {National Information and Documentation Center (NIDOC), Academy of Scientific Research and Technology (ASRT)}, issn = {1110-0206}, eissn = {2357-0903}, doi = {10.21608/ejoh.2013.1216}, abstract = {THIS INVESTIGATION was undertaken to study the effect of foliar spray with Ca and B at different concentrations on some fruiting parameters and fruit characteristics as well as leaf nutritional status of "Kelsey" plum trees.

Moreover, fruit physical properties (weight, volume, firmness, dimensions and fruit shape index) and chemical characters (TSS %, acidity % and TSS/acid ratio) were significantly improved as a result of the highest rates of both Ca and B foliar spray treatments either alone or in combination compared to the control. In addition, leaf nutrient content of some macroelements (N, P, K, Ca and Mg) and some micro-nutrients (Fe, Zn, Mn and B) were generally increased with the different treatments during both 1st and 2nd seasons of study.  Undoubtedly, it could be concluded that, foliar applications of (Ca) and (B) either alone or in combinations exhibited a positive and a significant influence on fruit quality of "Kelsey" plum trees.

Moreover, regenerated plants were also decreased with the increasing of salt concentration. On morphological level, the 1000 mg.L-1 concentration revealed high measurement in compare to the control.

Increment of salt concentration reduced both of the fresh weight and relative growth of fresh weight gradually from the 1000 mg.L-1 to 4000 mg.L-1.  Chemically, proline, sodium and chloride content were gradually increased with the increasing of sodium chloride concentrations. Meanwhile, salinity stress recorded drastic effect on chlorophyll content especially at 4000 mg.L-1, total chlorophyll content were decreased by the increasing of salt concentration.
