Abstract:
Taking the seedlings of spinach as materials.To investigate the effect of electrostatic field on seed germination and seedling growth of spinach,seven chemicals treatments and nine different intensity of electrostatic field treatments were set up with the distilled water treatment as control.The results showed that,the electrostatic field treatment (50 kV/5 cm×20 s) significantly increased the germination potential,germination rates and germination indexes of new spinach seeds,with 3.11,2.00,2.21 times higher than those of the control group,respectively.While for the aged seeds,the highest germination potential,germination rates and germination indexes were found in 50 kV/5 cm×10 s treatment.And the germination rate in 50 kV/5 cm×20 s treatment was as high as that in the 50 kV/5 cm×10 s treatment.For the seedlings from new seeds,their leaf widths,leaf lengths,petiole lengths and plant heights showed no differences between each treatment,while their shoot fresh weights were found obviously increased under four different electrostatic field intensity (50 kV/5 cm×5 s,50 kV/5 cm×10 s,50 kV/5 cm×20 s,100 kV/5 cm×20 s) and five chemical treatments (0.1 g?L-1 GA,100 mg?L-1 PEG 8000,25 g?L-1 choline chloride,1% boric acid,0.1% KNO3).No difference of shoot fresh weight was found between these nine treatments,except 100 mg?L-1 PEG 8000 treatment.For the seedlings from aged seeds,their blade weights,blade lengths,petiole lengths,plant heights,root lengths and shoot fresh weights under six electrostatic field intensity (25 kV/5 cm×5 s,25 kV/5 cm×20 s,50 kV/5 cm×10 s,50 kV/5 cm×20 s,75 kV/5 cm×20 s,100 kV/5 cm×20 s) treatments were similar to those under 0.1 g?L-1 GA and 50% H2SO4 treatments.All these showed that electrostatic field can improve spinach seed germination and seedling growth.Two values of electrostatic field intensity 50 kV/5 cm×20 s and 50 kV/5 cm×10 s can be used for new and aged seeds germination respectively.
