    地球温暖化に伴う気候変動の作物生産への影響に関する基礎的知見の蓄積の一環として,異なる栽培温度環境 下におけるダイズの生育と有用ダイズ根粒菌の接種効果および感染ダイズ根粒菌群集構造への影響について調査 を行った.供試ダイズ品種として,‘オリヒメ’,‘ボンミノリ’,‘フクユタカ’ を用い,供試菌株として Bradyrhizo- bium diazoefficiens USDA110T を用いた.栽培は温度傾斜型チャンバー内で行い,低温区,中温区,高温区を設 けた.異なる温度環境下での栽培試験の結果,無接種区と比較して,USDA110 の接種により主茎長,主茎節数, 茎葉乾物重,莢数,莢乾物重,地上部乾物重,根粒数が有意に増加したが,栽培温度の上昇により根粒数を除く項 目が有意に減少した.各調査項目間の相関係数は根粒数と茎葉乾物重との関係など多くの組み合わせにおいて有意 な正の相関関係を示した.USDA110 の根粒占有率は,全ての温度区で接種した USDA110 が優占したが,低温区 と中温区,低温区と高温区を比較すると栽培温度の上昇により減少する傾向を示した.以上の結果から,高温環境 下では根粒数が減少することでダイズの生育が抑制され,その後の生育や収量に影響すると考えられた.しかし, 根粒数と USDA110 の根粒占有率を確保することができれば栽培温度の上昇によるダイズの生産性低下を抑制する ことができると考えられる.

  • Effect of salt stress on soybean growth and nodulation under inoculation with soybean rhizobia Reviewed

    Salinity is one of the major problems when it comes to soil fertility and agricultural productivity. In this regard, this study aimed to elucidate the influence of four salinity levels (0, 20, 50, 100 mM NaCl) on the soybean growth and the nodulation by rhizobia inoculated on the soybean variety CNS. Additionally, the compatibility of soybean varieties with the seven representative strains of rhizobia was also investigated. Through the compatibility test, it was revealed that the Sinorhizobium (Ensifer) fredii USDA 191 and the three bradyrhizobia (Bradyrhizobium japonicum USDA 6T, B. elkanii USDA 31, and B. diazoefficiens USDA 110T) showed compatible nodulation with the Rfg1 genotype soybean, whereas, the S. fredii USDA 192, 193, and 205T showed incompatible nodulation. The inoculation tests with bradyrhizobia (USDA 31, 110T) and sinorhizobia (USDA 191, 192, 193) indicated a better growth of soybean for bradyrhizobia than the sinorhizobia until 50 mM NaCl. Note that even though the symbiotic efficiency at each strain was not different among 0, 20, and 50 mM NaCl treatments, the symbiotic efficiency of bradyrhizobia was higher than the sinorhizobia at each NaCl treatment. The result of the mix inoculation test indicated that the nodule occupancy rate of strain USDA 191 increased significantly along with the NaCl concentration but strain USDA 110T showed an opposite response. These results indicate a positive relationship between the soybean growth and the nitrogen fixation ability of the inoculant under salt-stress conditions. Furthermore, the results obtained from the mix inoculation test partly describe the dominance of sinorhizobia under saline conditions.

    Most soybean production in Saga and Fukuoka Prefec- tures is conducted on upland paddy fields. This agricultural system involves the management of soybean Bradyrhizobia, both to increase the soybean yield and to mitigate the emission of N2O gas from soybean fields. If soybean ger- mination damage caused by excess soil water can be avoided by the construction of ridges in the field, the rotational crop production of paddy rice and soybean will allow good agricultural performance for Asian monsoon regions.
