Tarom region of Zanjan province is one the olive production centers in Iran, which faced a crisis salinity stress following salinization water resources. The selection tolerant cultivars using pivotal characteristics interesting challenges. This study was conducted to investigate behavior ‘Zard’, ‘Abou-satl’, and ‘Arbequina’ context marginal waters. Therefore, one-year-old self-rooted plants th...

Soluble sugar accumulation pattern and contents were studied in two Iranian melon cultivars, ‘Suski Sabz’ and ‘Jalali Zard’ (Cucumis melo L. Inodorous). Sucrose, glucose and fructose contents were determined in different mesocarp tissues of developing fruits during days after pollination (DAP). They were characterised by enhanced accumulation of glucose and fructose during early fruit developme...

one-year-old seedlings of olive cultivars, zard, roghani, koroneiki and manzanilla, were transplanted to different sets of pots each pot containing 2000g of sterilized sandy loam soil. the experiment was conducted in a completely randomized design of 32 treatments, each in five replications. treatments were comprised of: control, mere nematode, mere fungus, and fungus+nematode. pots were inocul...

a factorial experiment based on completely randomized design (crd) was performed with three replications to investigate the interaction between salinity and nh+4 / no-3 ratio on olive saplings. four levels of salinity (0, 50, 100,150 mm) and different ratios of nh+4/ no-3 (0:14, 2:12, 4:10, 6:8) were applied on one-year old olive saplings grown in perlite: sand media (1:1). results indicated th...

pollen grains of five olive cultivars (olea europaea l .) were examined, using scanning electron microscopy (sem) for identification purposes. four measurments, polar axis (p), equatorial diameter (e), p/e ratio and exine patterns were made. forty pollen grains of each cultivar were viewed before finally selecting a representative pollen grain. polar diameter ranged between 22.76 μm for the...

ABSTRACT- Olive (Olea europaea L.) is one of the most valuable and widespread fruit trees in Iran. Salt stress-induced changes in membrane stability, photosynthesis and antioxidant enzyme activity were examined on four olive cultivars (Dakal, Shiraz, Zard and Amigdalifolia) by emphasizing the correlation between measured parameters and ion (K+, Na+) accumulation. Plants were subjected to four s...
