- Abstract
The application of nanomaterials is a promising tool to achieve more efficient in vitro propagation. This study evaluated the effectiveness of rice husk derived biogenic silica nanoparticles (SiO2 NPs) and zinc oxide nanoparticles (ZnO NPs) on the growth and proliferation of in vitro cultures of quince rootstock 'QA'. In vitro cultures were exposed to six levels of SiO2 NPs (0, 1, 5, 25, 50, 100 mg L− 1) and seven levels of ZnO NPs (0, 0.5, 1, 2.5, 5, 25, 50 mg L− 1). Proliferation and growth rate were determined in plantlets recovered from ZnO NPs and SiO2 NPs-treatments and controls that were grown under in vitro conditions for 35 days. The results showed in vitro shoots of quince rootstock QA treated with SiO2 NPs at a concentration of 1 mgL− 1 had the highest number of axillary shoots (2.46). Also quince rootstock QA plantlets regenerated from ZnO NPs-treatments showed the highest shoot length and the number of leaves at a concentration of 2.5 mg L− 1 (6.86 and 14.26, respectively). This research demonstrated the use of 1 mg L− 1 of SiO2 NPs and 2.5 mg L− 1 of ZnO NPs in the tissue culture medium may improve proliferation and growth rate in quince rootstock 'QA' explants.
