Pistillate flower abortion (PFA) in walnuts is defined as the drop of female flowers with or without pedicles within 10–15 days after flowering. This situation is commonly observed in some walnut cultivars causes dramatic yield losses. ‘Şebin’ is a popular walnut cultivar among farmers in Turkey due to the quality of its fruit, yield and ease of marketability. However, in some orchards, established with this cultivar, has a fruitlessness problem. In the present study, the effects of Aminoethoxyvinylglycine (AVG, the commercial brand name is ReTain) (0, 62.5 and 125 ppm doses) and AVG plus GA3 (45, 135 and 270 ppm doses) treatments to prevent abortion in cv. ‘Şebin’ were investigated. The experiments were conducted in two different ecologies. The treatments were carried out just before the receptivity period of female flowers of cv. ‘Şebin’. The results showed that, the female flower abortion ratio of ‘Şebin’ walnut cultivar were 87.78% in Tokat ecology and 77.78% in Niksar ecology. The fruit set ratio by 125 ppm AVG treatment was determined to be 60.89% for Niksar and 57.56% for Tokat ecological conditions. The highest fruit set was obtained from 125 ppm AVG combined 270 ppm GA3 treatment and this ratio was determined to be 93.89% for Niksar ecological conditions whereas it was determined to be 83.33% for Tokat ecological conditions. As a result, it was found that AVG alone or in combination with GA3 is effective treatments in reducing female flower abortion for ‘Şebin’ walnut cultivar.

Opadanie kwiatów żeńskich u orzechów określa się jako spadanie żeńskich kwiatów z szypułkami lub bez, w ciągu 10–15 dni po kwitnieniu. Zjawisko to, powszechnie obserwowane u pewnych odmian orzecha, powoduje znaczne straty w plonie. ‘Şebin’ jest popularną odmianą orzecha wśród farmerów w Turcji ze względu na jej owoce, plon oraz łatwość sprzedaży. Jednak niektóre sady założone z tą odmianą mają problem braku owoców. Niniejsze badanie określa wpływ zabiegów aminoetoksywinyloglicyną (AVG, nazwa handlowa ReTain) (w dawkach 0, 62,5 i 125 ppm) oraz AVG plus GA3 (dawki 45, 135 oraz 270 ppm) stosowanych, aby zapobiec opadaniu. Doświadczenia przeprowadzono w dwóch różnych lokalizacjach. Zabiegi przeprowadzono tuż przed okresem receptywności żeńskich kwiatów odmiany ‘Şebin’. Wyniki pokazały, że wskaźnik opadania kwiatów odmiany ‘Şebin’ wynosił 87,78% w uprawie w Tokat oraz 77,78% w uprawie w Niksar. Współczynnik zawiązanych kwiatów pod wpływem zabiegu 125 ppm AVG określono jako 60,89% dla Niksar oraz 57,56% dla ekologicznych warunków Tokat. Najwięcej zawiązanych kwiatów osiągnięto przy zabiegu 125 ppm AVG w połączeniu z 270 ppm GA3: 93,89% dla warunków ekologicznych Niksar oraz 83,33% dla warunków ekologicznych Tokat. W rezultacie stwierdzono, że sam AVG lub w kombinacji z GA3 jest efektywnych zabiegiem ograniczającym spadanie kwiatów dla odmiany orzecha ‘Şebin’.
