“…H 2 O 2 plays an essential role in signal mediating in stomatal closure, which is inducted by abscisic acid [17,20]. Pretreatment with H 2 0 2 induces higher micro-tuberization, increases weight, and enhances the sprouting of microtubers [21]. López-Delgado et al [22], based on research where potato plants were sprayed twice weekly, from 21 to 90 days after planting with 0.02 % or 0.17 % H 2 O 2 concentrations, indicated that treatments significantly enhanced tuber starch accumulation by between 6.7% and 30%, and stems were up to 27% thicker, mainly due to enlarged medullar parenchyma cells, relative to control.…”

The biocidal properties of hydrogen peroxide (H2O2) could be used in plant protection. However, the effects of H2O2 foliar spraying on the performance of the potato photosynthetic apparatus are still unclear. A pot experiment was conducted to investigate the effect of foliar spraying, which was done twice, with various H2O2 concentrations (1, 3, 6, 12, and 18%) on the potato photosynthetic apparatus efficiency and antioxidant capacity. The measurements were taken four times: on the first and seventh day after each application. Foliar spraying with 1% H2O2 concentration was the most stimulating for the course of physiological processes in leaves. Further increased doses of H2O2 enhanced stress in plants which is manifested by a decrease in pigment levels, photosynthetic attributes, antioxidant capacity in leaves, and fresh mass above-ground parts of potato plants. The intensive effect of spraying was particularly observed on the first day after application, while later, the activity of the photosynthetic apparatus and antioxidant capacity increased. The study provides information that foliar spraying with 1% H2O2 can be taken into account in further research on the development of a potato plant protection methods.

“…First of all, disease-free, high-quality potato seeds can be obtained; and, compared to other propagation techniques, microtubers are more robust and easier to handle, which favors automatic planting processes (Dhital & Lim, 2012;Motallebi et al, 2013). Secondly, microtubers facilitate the maintenance and exchange of genetic material because small samples can be preserved, and subsequently sent in aseptic conditions (virus-free), even to countries with strong phytosanitary regulations (López, Sánchez, Mora, & Martínez, 2012). Thirdly, they have also been experimental research tools in many areas including plant metabolism, germplasm selection and evaluation, transformation, somatic hybridization, and in vitro selection of agronomically important characters such as maturity, abiotic stress tolerance, among others (Dobránszki et al, 2008).…”

In order to understand the performance of Solanum tuberosum L. "Floresta" in producing microtubers, the effect of four concentrations of boric acid (6.2 mg l ) under two conditions-1) 8 hour dark and 2) 16 hour light photoperiod and 8 hour dark-was evaluated under in vitro culture conditions. Full-strength Murashige and Skoog medium was used as a control. The data analysis for the number and biomass of microtubers were significant for the condition (p ≤ 0.05). Concerning the concentration of boric acid and the interaction between factors, a significant difference was obtained for biomass (p ≤ 0.05). In dark conditions, a greater number of microtubers was obtained, although the biomass was lower compared to the light conditions where the biomass was higher, and the number of microtubers was lower. A concentration of 9.3 mg l -1 of boric acid in both types of conditions was the best treatment to produce a greater number and more biomass of microtubers. The differences identified in this work with regards to the number and biomass of microtubers were probably the combined result of genotype and specific culture conditions. Even considering this, the use of lighting conditions is proposed to induce larger and greener microtubers.
