The species of Pistacia vera, P. mutica and P. khinjuk can be used as rootstocks for pistachio cultivars due to their adaptability to severe environmental conditions and resistance to some pests and diseases. However, low percentage of seedling survival following transplanting has been a major problem. This study was conducted to test the effects of different concentrations of indolebutyric acid (IBA) on root regeneration of transplanted bare-rooted seedlings of these three species. The seedlings treated with IBA at all concentrations tested (1000, 1500, 2000, 2500 and 3000 mg l-1) developed more roots, which were longer and had higher fresh and dry weight, and increased the survival rate of treated seedlings compared to their respective controls. The most effective concentrations in this respect were 2000 and 2500 mg l-1. There was a significant interaction between the species and IBA concentration. Shoot height, root and shoot diameter, leaf number, shoot fresh and dry weight were not affected by IBA. Results also showed that survival rate of the seedlings was significantly correlated with root number, length and fresh and dry weight.

Gatunki Pistacia vera, P. mutica i P. khinjuk mogą być zastosowane jako podkładki dla odmian pistacji ze względu na ich przystosowanie do zróżnicowanych warunków środowiska i odporność na szkodniki i choroby. Jednakże głównym problemem jest niski stopień przeżycia po szczepieniu. W przeprowadzonych badaniach testowano wpływ różnego stężenia kwasu indolilomasłowego (IBA) na regeneracj ę korzeni u szczepionych siewek tych trzech gatunków. Siewki traktowane różnymi stężeniami IBA (1000, 1500, 2000, 2500 i 3000 mg l-1) wytwarzał więcej korzeni, byly dłuższe, miafy większą świeżą i suchą masę i wykazywał wyższą prze żywalność w porównaniu z siewkami kontrolnymi nietraktowanymi. Stężenia IBA 2000 i 2500 mg l-1 dawafy najlepszy efekt. Otrzymane wyniki wykazują, że prze żywalność siewek była istotnie skorelowana z liczbą korzeni i ich d ługością, a tak że świeżą i suchą masą korzeni.
