摘要

盐度是限制作物产量的最严重的非生物胁迫之一。由于咸水侵入耕地以及使用化肥和杀虫剂,突尼斯受盐影响的地区正在迅速扩大。因此,在限制因素的影响下,需要作出很大的努力来保持作物生产。本研究从沿海盐渍地分离鉴定了与两种盐生植物相关的PGPB。这些品系在盐碱条件下进行了提高作物产量的试验。选取MA9、MA14、MA17和MA19 4个菌株,接种了pgpb的植株相对健康且水分充足,而未接种的植株叶片在125 mM NaCl的作用下干燥。接种植株的水分含量(PWC)也显著高于未接种植株。在温室试验中,我们的数据表明,在非无菌土壤上添加NaCl进行种子生物洗膜试验,可以通过显著增加植物生长试验中根冠长、根冠干重、根系面积和千粒重,鉴定出提供最佳蔬菜标准的最有效分离株。在添加NaCl的土壤样品中,种子生物雾化的效果比未处理的土壤样品更明显。利用高效的PGPB菌株进行种子生物灌洗,可诱导小麦耐盐性,从而提高小麦在盐胁迫下的产量。

Halotolerant PGPB Seed biopriming Induces wheat salinity tolerance
Salinity is one of the most severe abiotic stresses limiting crop yield. Salt-affected area in Tunisia is fast escalating due to intrusion of saline water on arable land and use of chemical fertilizers and pesticides. Thus, a great effort is required to preserve crop production under limiting factors. The present study was conducted to isolate and identify PGPB associated with two halophyte plants from coastal saline site. These strains were tested for improved crop productivity under salinity conditions. Four strains namely MA9, MA14, MA17 and MA19 were selected The PGPB-inoculated plants were relatively healthy and hydrated, whereas the uninoculated plant leaves were desiccated in the presence of 125 mM NaCl. The percentage of water content (PWC) in the plant was also significantly higher in inoculated plants compared to uninoculated ones. Under greenhouse experiments, our data revealed that experiments using seed biopriming on non-sterile soil supplemented with NaCl permitted to identify the most efficient isolates which offered the best vegetable criteria by significantly increasing root and shoot length, root and shoot dry weights, area of the root system and thousand seed mass in plant growth trials. The benefic effect of seed biopriming was more pronounced in soil samples added with NaCl than that of untreated soil. Seed biopriming by efficient PGPB strains induced salinity tolerance of wheat and therefore enhanced their productivity under salinity.
