摘  要：
旨在明确内生真菌发酵液与盐胁迫互作对小麦种子萌发和幼苗生长的影响.以'淮麦44'为材料,开展室内发芽试验和温室盆栽试验,获得小麦种子萌发和幼苗生长的数据.结果表明低盐浓度促进小麦种子的萌发与幼苗的生长,高盐浓度抑制其萌发与生长.小麦种子发芽率、发芽势和发芽指数以及幼苗胚根长、胚芽长都表现出先升后降的趋势,而幼苗的鲜干重及地上株高和地上鲜重表现出直线下降的趋势.喷施10%内生真菌发酵液对小麦种子的发芽率、发芽势,幼苗的干鲜重、胚根长以及幼苗地上株高有显著的促进作用.内生真菌发酵液能促进盐胁迫条件下小麦种子的萌发和幼苗生长,从而提高小麦耐盐性.

摘  要：
The aim was to clarify the effects of the interaction between endophytic fungal fermentation broth and salt stress on wheat seed germination and seedling growth.Using'Huaimai 44'as the material,indoor germination experiments and greenhouse pot experiments were conducted to collect data on wheat seed germination and seedling growth.The results showed that low salt concentration promoted the germination and seedling growth of wheat seeds,while high salt concentration inhibited their germination and growth.With the increase of salt stress concentration,the germination rate,germination potential and germination index as well as radical length,and embryo length of wheat seeds showed a trend of first increasing and then decreasing,while the fresh and dry weight and aboveground plant height and fresh weight of seedlings showed a linear downward trend.Spraying 10%endophytic fungal fermentation broth had a significant promoting effect on the germination rate,germination potential,dry and fresh weight,radicle length,and aboveground plant height of wheat seeds.Endophytic fungal fermentation broth can promote the germination of wheat seeds and seedling growth under salt stress conditions,thereby improving wheat salt tolerance.
