| 摘 要： | 为给光合细菌(PSB)的开发应用提供理论依据,用不同浓度的PSB-B菌液对临丰3号小麦种子做浸种处理,研究其对小麦种子萌发的影响。结果表明,100倍PSB-B菌稀释液可提高种子的发芽率,而原菌液有抑制作用。在萌发后期,PSB-B菌液处理组的小麦种子芽长均高于对照组(P<0.05),其中稀释10倍PSB处理组的芽长达到了14.2 cm。适当浓度的PSB-B处理会提高小麦萌发过程中可溶性蛋白和还原性糖含量(P<0.05),并对细胞膜具有一定的保护和修复作用。说明PSB-B可通过改善小麦种子的生理生化代谢,促进其萌发。 |

| Abstract: | To survey the influence of soaking weeds with Photosynthetic bacteria-B on germination of wheat seed,seeds of wheat Linfeng 3 were soaked in different concentrations of PSB-B solutions.The results showed that: 100-fold dilution of PSB-B could increase the germination rate,however,the original bacterium solution decreased the germination rate;the shoots of wheat seeds treated with PSB-B bacilli were higher than that of control group at mid-late germination stages(P<0.05).The mean shoot length of wheat seeds ... |
