Abstract:

Wild pistachio seeds have a hard coat and deep physiological dormancy, which declines their germination success. In this study, the effect of seed priming with carbon nanotubes was studied on two species of wild pistachio (Pistacia atlantica and P. Khinjuk) and was then compared with common treatments. For this purpose, seeds of each species were primed for four hours in solutions containing 0, 10, 25, 50, 75 and 100 mg / L of carbon nanotubes. In addition, some of the seeds were also treated by the common acid concentrations (65%, 5 and 10 min) and cold treatments (4 °C for one month), followed by an analysis of their germination characteristics. According to the results, carbon nanotubes affected the germination characteristics of the both species. The highest germination rate of P. khinjuk occurred under 75 mg/l and for P. atlantica at 10 mg / l. for P. atlantica, whereas the lowest germination was observed in acid (5%) and control treatments. Although cold treatment showed higher germination (18.33%) compared to control and acid-treated seeds, it was less than carbon nanotube treatments. For P. khinjuk, the lowest germination was also observed for acid treatment (11.67%). The seed germination rate and percentage of both species at concentrations of 100 mg/L were lower than those at concentrations of 10 and 75 mg/l, thus the use of lower concentrations of the nanomaterial economically is recommended.
