The effect of three salicylic acid (0, 50 and 100 mg l-1) and K2SO4 (0, 0.1 and 0.2 %) levels on some characteristics nut and physiological parameters of pistachio trees cv. ‘Owhadi’ were investigated. Treatments were applied at endospermic growth stage of seed and cotyledons appearance. The results showed that potassium increase yield, splitting percentage; nut fresh mass and kernel dry mass a...
In this study the artificial pollination of pistachio was investigated. Two types of pollen of local selective genotypes (Q1 and Q2) which were different pollinizers were used. The experiment had six treatments. Qazvini and Ohadi cultivars were pollinated with supplementary pollinations as treatment which was covered with cotton bag, natural pollination as a control which was not covered and tw...
In order to determine effect salicylic acid and Zn on characteristics of pistachio nut (Pistacia vera L. cv. Owhadi), the experiment was carried out as factorial in the framework of CRD design with three replications. The results showed that salicylic acid and Zn increased nut fresh weight and decreased blank nut percentage. The application of salicylic acid decreased splitting percentage and k...
This study evaluated the effect of artificial pollination on pistachio trees in an orchard at a low ratio of male to female trees in Qazvin province, Iran, over the years 2012-2013. Experimental factors included three female cultivars (Akbari, Owhadi, Kalebozi) and three types of pollinizer (Control, GA, and GB) with three replications. In each female tree, two branches were selected in the nor...
Experiments were conducted during 1996-1997 in Nough of Rafsanjan to evaluate double pollination on fruit set and development of pistachio nut. In the first experiment, Owhadi cultivar was pollinated by a combination of pollen from Beneh (P. mutica F&M), Atlantica (P. atlantica Desf) and Soltani (P.vera L.). In the second experiment, Owhadi cultivar was pollinated by pollen from Beneh, Atlantic...

درختان پسته با مشکلات فیزیولوژیکی مهمی چون ریزش جوانه های گل، ریزش میوه ها، پوکی، بدشکلی, ناخندانی, ترک خوردگی, زودخندانی و نوک سیاهی میوه مواجه هستند که این عوامل سبب کاهش عملکرد درختان و کیفیت محصول می گردند. در این پژوهش، اثر محلول پاشی با کودهای کلرید کلسیم (با غلظت 5/0 و 1 درصد)، نیترات کلسیم (با غلظت 5/0 و1 درصد) و کلات کلسیم (با غلظت 1/0 و 2/0 درصد) در سه مرحله شامل یک هفته قبل از تمام گ...
Pistachio suffers from some physiological disorders such as fruit abscission, endocarp lesion, blankness, non-split, early-split and deformed nuts. In this experiment, the effects of calcium nitrate (2 gr/lit), calcium chloride (2 gr/lit), boric acid (200 ppm) and their combination treatments were investigated on physiological disorders of ‘Kaleh-Ghoochi’ pistachio. Foliar application was appli...
Pistacia era ‘Kerman’ (pistachio nut) typically produces high numbers of seedless or blank fruits. Patterns of vascular transport into fruits and ovules were studied over 3 years by following the movement of disodium fluorescein solution from cut branches into developing fruitlets. Early in the season, vascular conductivity is intact through to the chalazal end of the ovule. Soon afterwards, t...
This study was conducted to identify Mincane cv clones with superior physical traits in the Trabzon province, Maçka district, Esiro?lu region between 2014 and 2019. Selection research area based on objective revealed 14 traits. In these selected clones, yield, number of nuts per cluster, nut characteristics, kernel weight, shell thickness, percentage, shriveled kernel, cavity, blank split sutur...
