Aflatoxins, carcinogenic toxins produced by Aspergillus fungi, contaminate maize, peanuts, and tree nuts in many regions of the world. Pistachios are the main source of human dietary aflatoxins from tree nuts worldwide. Over 120 countries have regulations for maximum allowable aflatoxin levels in food commodities. We developed social network models to analyze the association between nations' af...

OBJECTIVES Stillbirth is an undesirable outcome of pregnancy. In light of the increasing use of pesticides and growing concerns about the possible health effects of agricultural pesticides, we investigated the effect of exposure to pistachio pesticides on stillbirth in pregnant mothers. METHODS This case-control study was conducted in Rafsanjan, Iran from 2011 to 2012. A total of 125 females ...

Pistacia vera cv Badami-e-riz and P.vera cv Ghazvini are the most important and popular rootstocks in Iran, which tolerate salinity and phytophthora fungi. This study was conducted to evaluate the effects of various concentrations of polyamines and IBA on root regeneration of transplanted bare- rooted ‘Badami-e-riz’ and ‘Ghazvini’ pistachio rootstocks. The mean comparison between IBA and polyam...

ORIGIN AND HISTORY The pistachio is native to western Asia and Asia Minor, where it is still found growing wild in numerous hot, dry locations in Lebanon, Palestine, Syria, Iran, Iraq, India, Southern Europe and the desert countries of Asia and Africa. It was introduced to Europe at the beginning of the Christian era. The first pistachio introductions to the United States were by the USDA plant...

In order to evaluate the inter-specific hybrid of P. atlantica × P. vera cv. ‘Badami Zarand’ to salinity stress, an experiment was conducted as a factorial based in a completely randomized design with 0, 60, 120 mM salinity levels of NaCl2, CaCl2 and MgCl2 (3:2:1) on two rootstocks ‘Qhazvini’ and ‘Badami Zarand’ and an inter- specific hybrid of P. atlantica × P. vera cv. ‘Badami Zarand’. Minera...

Plant grafting is an important technique for horticultural and silvicultural production. However, many rootstock plants suffer from undesirable lateral bud outgrowth, low grafting success rates or poor rooting. Here, we used a root-predominant gene promoter (SbUGT) to drive the expression of a tryptophan-2-monooxygenase gene (iaaM) from Agrobacterium tumefaciens to increase auxin levels in toba...

Grapevine (Vitis) rootstock varieties or cultivars are used to confer resistance and tolerance to insect and disease pests, unfavorable soil conditions, and other environmental conditions to cultivars that are susceptible to these conditions but otherwise have desired properties. The need to genotype and thoroughly identify grapevine rootstock varieties in the grape industry has become increasi...

Use of dwarfing rootstocks has dramatically increased the profitability of fruit production by reducing production costs, reduced chemical use and higher density plantings. Despite the importance of rootstock-induced dwarfing, the cause of this phenomenon is not known. Using two commercially available graft combinations consisting of a sweet cherry scion, 'Bing', on a dwarfing rootstock (Gi5) o...

Reports that “own rooted” Chandler walnuts (Chandler clone) out preformed grafted trees stimulated the creation of this replicated trial to investigate the performance of Chandler clone trees, Chandler clone grafted to Chandler clone rootstock, Chandler clone grafted to three selections of paradox rootstock and Chandler clone grafted to a vigorous English rootstock. Rootstock trees were planted...
