摘　　要：该研究通过用不同稀释倍数的残次果发酵液处理野生秋子梨苗,探究其对野生秋子梨苗的生长发育及光合生理指标的影响。结果表明,较低稀释倍数的残次果发酵液对野生秋子梨苗的营养生长产生抑制,降低其叶片的光合能力;较高稀释倍数的残次果发酵液能促进野生秋子梨苗的光合作用,利于其营养生长,尤以施用残次果发酵液稀释500倍液的效果最佳。In this study,the effects of the fermentation broth of the defective fruit with different dilution ratios on the growth and development of the wild autumn pear seedlings and the photosynthetic physiological indexes were investigated.The results showed that the fermentation liquid of the defective fruit with lower dilution ratio inhibited the vegetative growth of the wild autumn pear seedlings and reduced the photosynthetic capacity of its leaves;The residual fruit fermentation liquid with higher dilution ratio can promote the photosynthesis of wild autumn pear seedlings and facilitate its nutrient growth,especially the effect of using residual fruit fermentation liquid diluted by 500 times is the best.
