| 摘 要： | 采用盆栽试验,初步研究内生真菌印度梨形孢诱导提高玉米抗旱性的效应。结果显示,在自然干旱胁迫下,根长、根鲜重、根干重、叶片数、叶面积、叶绿素含量等指标接种印度梨形孢的玉米幼苗比未接种的明显增加,差异达到显著、极显著水平;根干重、叶绿素含量等性状,接种印度梨形孢干旱胁迫处理的幼苗显著地高于未接种干旱处理,表明印度梨形孢真菌具有促进玉米幼苗生长的作用,能有效增强玉米幼苗的抗旱性。

| Abstract: | A pot experiment was conducted to reveal the effects of endophytic fungus Piriformospora indica fungi that could confer drought tolerance in maize.The results showed that significant increase under natural drought stress on the indicators of length of roots,fresh weight of roots,dry weight of roots,number of leaves,area of leaves,chlorophyll content,maize seedlings inoculated Piriformospora indica fungi than the unvaccinated,and the difference reached a significant level,traits of dry weight of roots,chlorophyll content were significantly higher than the "non-drought" control.The present work indicated that Piriformospora indica has a role in promoting the growth of maize seedlings,and could effectively enhance the drought tolerance of maize seedlings. |
