Abstract

: Objective Physical technology is beneficial to the growth of plants and has a good application prospect. The effects of different electric fields, time and their interaction on seed germination characteristics were analyzed to provide theoretical reference for seed germination and sustainable management. Method This study used Acacia cincinnata seeds as the research object, using indoor simulation experiments, with different voltage intensities and treatment time as control factors, voltage intensities were 0～1.0 kV·cm⁻¹, and time treatments were 0～60 min to study the effects of different voltage intensities and time interactions on seed germination characteristics. Result The results showed that with the increase of voltage intensity and treatment time, the germination rate, germination potential and germination index of A.cincinnata seeds showed varying degrees of change. Among them, the germination rate decreased first, then increased and then decreased with the increase of voltage intensity at 15 min, 30 min and 60 min, but the germination rate increased first and then decreased with the increase of voltage intensity at 45 min. The germination potential and germination index were the best under the voltage intensity of 0.6 ～ 0.8 kV·cm⁻¹ and the treatment time of 45 min, and there was a significant difference compared with CK ( P＜0.05 ). After nonlinear regression analysis, the optimal regression equation under different voltage intensity and time interaction was: Y=7.73+135.23X₁+1.24X₂−86.16X₁²−0.00911X₂²-0.75X₁X₂ (R²=0.81, P＜0.05). Cluster analysis showed that the interaction of electric field and time had a very significant effect on germination index. Conclusion The interactive treatment of electric field and time had a certain effect on the germination characteristics of A.cincinnata seeds. The germination rate was the highest at 0.6 kV · cm⁻¹ for 45 min, indicating that the appropriate voltage intensity and treatment time could improve the germination rate of A. cincinnata seeds.
