“…In our study, the cultivar 'Uzun' had a higher yield than 'Siirt' , which contrasts with the findings of several other studies that have shown that 'Siirt' has a higher yield than 'Uzun' (Arpacı et al, 1995;Açar et al, 2005Açar et al, , 2011. The yield of 'Uzun' was correlated with the concentration of the Tarımbor application (r = 0.9257), but no such correlation was observed for 'Siirt' (r = 0.0490).…”

In Turkey, more than 95% of the pistachio (Pistacia vera L.) orchards are not irrigated. Therefore, a 4-year field trial was conducted to determine the effect of Tarımbor fertiliser (containing 18.5% boron [B]) on the yield, quality, and B content of two pistachio cultivars ('Uzun' and 'Siirt') planted under nonirrigated conditions. Tarımbor was applied to the pistachio trees as a soil application (0, 200, 400, and 600 g/tree) and a foliar spray (0%, 0.1%, 0.2%, and 0.3% w/v, using a tractor-mounted sprayer at the 'early bud break' stage and the 'fully leafed out' stage). Both the soil and foliar applications of Tarımbor had a significant effect on the pistachio yield, quality, and B content compared with the control. However, the foliar application resulted in greater improvements in the B content of leaves in both cultivars and the split nut ratio and kernel ratio in 'Uzun'. The greatest increases in yield were observed for the 0.3% foliar application for 'Uzun' (30%) and the 200 g/tree soil application for 'Siirt' (59%). In terms of quality, the application of Tarımbor appeared to have a greater effect on 'Uzun' than on 'Siirt'. No vegetative symptoms of B toxicity were observed in either cultivar when high concentrations of B were applied. Thus, Tarımbor could be used effectively as a foliar spray to enhance the B levels in the leaves of pistachio trees grown under nonirrigated conditions.

Subsequently, the effects of plant growth regulators, carbohydrates, polyamines, and phenolic compounds were also studied, and recently, molecular and biotechnology studies have been carried out to solve the issue of alternate bearing in pistachios (Crane and Nelson, 1971;Nzima et al, 1997;Vemmos, 1999a;Acar et al, 2006;Teale et al, 2006;Acar et al, 2011;Okay et al, 2011;Cetinkaya and Ozguven, 2016;Gundesli et al, 2019). Monselise and Goldschmidt (1982) described the possible endogenous (hormonal) factors that might influence the alternate bearing in fruit trees.…”

The regulation of auxin (indole-3-acetic acid, IAA) level in plants is a complex mechanism and the concept is not completely understood. There are many lines of evidence suggesting that amino acid conjugates of IAA play a vital role in auxin homeostasis, but the involved plant enzymes are still under investigation. In the present study, the alteration in the levels of auxin and its conjugates in the different physiological stages and organs, as well as its role in flower bud abscission in Pistacia vera L., were investigated. The levels of the auxin and its conjugates, such as IAA, indole butyric acid (IBA), IAA-Ala, IAA-Leu, IAA-Asp, and IAA-Glu, were analyzed by ultraperformance liquid chromatography-electrospray ionization-mass spectrometry (UPLC/ESI-MS/MS) technique. Among the auxin conjugates, IAA was the main conjugate and dominant indole detected in pistachio extract observed in this work. It has also been determined that quite a few organs of 'Off-year' trees have higher auxin content than 'On-year' trees. It was observed that the auxin level is low in fruit-bearing trees in both leaves and shoots. It affects fruit yield and fruit bud abscission and plays some role in the alternate bearing. Decreased levels of auxin were observed in most of the organs of 'On-year' trees during kernel development resulting in bud abscission. This study shows that auxin conjugates play an important role in IAA metabolism, particularly in flower bud abscission and fruit kernel development.
