Abstract
In vitro, applications of nanosilicon dioxide (SiO2) and chitosan were investigated for their effects on growth and proliferation of apple (Malus domestica Borkh. ‘Gala’) explants under osmotic stress induced by agar to simulate drought stress and under non-stressed conditions. The experiment included five levels of SiO2 (0, 25, 50, 100, and 200 mg L−1), two levels of chitosan (0 and 40 mg L−1), and two levels of agar (7 g L−1 and 9 g L−1) added to Murashige and Skoog medium. Under non-stressed conditions (7 g L−1 agar), application of SiO2 at 50 or 100 mg −1 increased proliferation of apple explants. Use of 50 or 100 mg L−1 SiO2 or 40 mg L−1 chitosan increased growth of apple explants under osmotic stress (9 g L−1 agar). This research suggests that use of SiO2 or chitosan may improve plant growth and tolerance to stress.
