Effects of chitosan oligosaccharide on the growth of maize and rapeseed during germination and seedling stages
In order to compare the effects of different concentrations(10、50、100、300 and 500 mg/L)of chitosan oligosaccharide on the germination and seedling growth of maize and rapeseed seeds,germination and seedling experiments were conducted to measure the growth indicators of maize and rapeseed.The results showed that different concentrations of chitosan had different effects on maize and rapeseed at different stages,and suitable concentrations of chitosan could promote the growth of maize and rapeseed.Maize treated with 100 mg/L chitosan seed soaking showed better growth during the germination stage,while the promotion effect of chitosan seed soaking on rapeseed germination stage was not significant.Spraying 50-100 mg/L chitosan oligosaccharide on the leaves had a better effect on promoting the growth of maize seedlings,while 500 mg/L chitosan oligosaccharide had a better effect on promoting the growth of rapeseed seedlings.
