Effect of electrostatic field on seed germination and seedling growth of Sorbus pohuashanesis

Abstract

A study was conducted to determine the effects of electrostatic field (ESF) treatment on seed germination and seedling growth of Sorbus pohuashanesis. The experiments were arranged by uniform design computed by the Data Processing System (DPS), including three levels of seeds soaking time, four levels of ESF intensity and four levels of ESF treatment time, with 12 treatments. Ten seeds were used in each treatment with three replicates. Seed vigor, seed germinating ability, emergence rate of seedling, survival rate of seedling, and seedling height and diameter, as well as the change in activities of superoxide dismutase (SOD), soluble protein contents, total chlorophyll contents, soluble total sugar contents in leaves of S. pohuashanensis seedlings were measured after ESF treatments. The experiment results show that ESF treatment could improve the water absorption ability of dry seeds of S. pohuashanensis, resulting in fast germination at room temperature under light conditions. Combined treatment of ESF with cold stratification could increase seed germination percentage significantly (to 42.20%),promote seedling height growth, affect leaf SOD activity, and could raise contents of total chlorophyll, soluble protein, and total soluble sugar in

Dependency of arabidopsis thaliana growth on DC electric field intensity

“…Yang also showed the increase of seedling length of Sorbus pohuashanesis with the similar field condition [6]. In our study, 2.5 kV/m, 5.0 kV/m, 10.0 kV/m and 15.0 kV/m of dc field were applied to Arabidopsis thaliana seeds for 96 hours and we obtained similar results with their experimental results; increase of germination rate and of stem length of seedling.…”

“…Krueger et.al reported that air ions stimulate the growth rate of Barley (Hordeum vulgare) seedling [4]. Some studies also showed that electric field could encourage the growth rate including earlier germination, higher germination rate, and faster growth [5,6]. Eing et al pointed out that the exposure of nanosecond pulse electric field, whose intensity is low as no plasmamembrane electroporation occurs, has a growth stimulating effects for Arabidopsis thaliana [7].…”

Stimulation of the germination and growth of different plant species using an electric field treatment with IrO2‐Ta2O5|Ti electrodes

“…Measurements were performed 8 weeks after treatment. All determinations were done at least in triplicate to assure the statistical error was less than 5% …”

Effect of a Pre-Planting Treatment of Seed Tubers With Low-Frequency Pulse Electric Field on the Growth of Potato Plants of Different Varieties

“…Thus, the positive effects of pre-sowing seed treatment with electrostatic field [15], cold plasma [16,17], alternating magnetic field [18], and electromagnetic field (EMF) of industrial frequency [19][20][21][22] on germination, development and productivity of plants has been demonstrated in vegetables, cereals and ornamental crops. Pre-planting treatment of seeds with low-frequency pulse electric field (LF-PEF) belonging to the same group of technologies has been proved to have a positive effect on the seed qualities and productivity of some agricultural crops including lettuce, parsley, red beet, and carrot [23][24][25][26].…”
