ABSTRACT: The viability, pollen tube growth and morphological characters associated with pistachio pollen quality are important for plant breeders and growers. Different kind of pollens of fruit trees has shown different morphological and pomological characteristics. Germination rate and growth of dry and wet pollen requires to be studied if confronted to low temperatures.

ABSTRACT: This study was aimed at characterizing four Tunisian pistachio cultivations (Pistacia vera) from the Mateur (North), Nabeul (North-East), Kairouan (Middle) and Sfax (Middle-East) regions and two varieties, Mateur and Ohadi, considering fatty acid composition and main lipid class contents (polar lipids, diacylglycerols, triacylglycerols and free fatty acids) in ripe seeds. Lipid classes were separated using thin layer chromatography, and fatty acid methyl esters (FAMEs) were analyzed by gas chromatography.

ABSTRACT: An experiment was carried out to assess the single and combined effects of salinity and phosphorus (P) on growth and chemical composition of pistachio seedlings (Pistacia vera L.) cv. Badami grown in a calcareous soil under greenhouse conditions. Pistachio plants were treated with four P levels [0, 60, 120, and 180 mg P kg–1 soil as calcium phosphate, Ca (H2PO4)2.2H2O] and four salinity levels [0, 1000 2000, and 3000 mg sodium chloride (NaCl) kg–1 soil] in a completely randomized design with three replications.

ABSTRACT: Differences in some physical, compositional and sensory characteristicsamongeight varieties of pistachio nuts (Aegina, Pontikis, Bronte, Cerasola, Joley, Kerman, Mumtaz and Sirora) from different origins were studied. The evaluated varieties were cultivated under the same field conditions and the dried nuts were utilised.

ABSTRACT: Field experiments were conducted in 2002 and 2003 on pistachio (Pistacia vera L., Anacardiaceae) in northwest Syria to assess the effectiveness of kaolin-based particle film, teflubenzuron, alpha-cypermethrin, and thiacloprid against pistachio psyllid Agonoscena targionii (Lichtenstein). The effects of particle film and insecticides on early and mid-season infestations of immatures were evaluated. Significantly fewer adults and nymphs were found on particle-film-treated trees compared with the untreated control.
