铜虫 (小有名气)

[求助] 促生细菌对鹰嘴豆作用结论部分 英译汉

The use of soil rhizosphere bacteria possessing the traits of plant growth promotion under saline stress is becoming prevalent worldwide to achieve sustainable agriculture along with soil reclamation through phytoremediation as well as bioremediation. The present study demonstrated the ability of native strains in saline areas to tolerate salinity and show plant growth-promoting potential. From a total of
176 bacterial isolates, 62 have the potential to tolerate salinity up to 1 M NaCl concentration. Five bacterial isolates were screened out that not only can tolerate high salinity but play an essential role in helping plants to establish and grow in salinity conditions. Isolate MSC1 increased the root length of treated plants by 71% and shoot length by 34% compared to untreated plants. MSC4 was another effective growth promoter and increased root length by 76%. Treatments with isolates MSC4 and MSC1
also yielded the maximum increase in the number of flowers by 63 and 54%, respectively. Plants inoculated with MSC4 and MSC1 showed an increase in the number of fruits by 112 and 105% in comparison with uninoculated controls. Thus, using strains with all the PGPR attributes can enhance plant growth under saline conditions.
青春无悔!
