- 摘要:
- 以磷高效大豆BX10和磷低效大豆BD2为材料进行水培,比较了品种间磷的吸收和同化效率差异以及二氢茉莉酸丙酯浸种(PDJ)对磷的吸收和同化的调控效果。低磷减少大豆干物质和P的积累,BD2减幅大于BX10;低磷通过增加根系活跃吸收面积、Imax和α值,减小Km、Cmin和β值来提高磷的吸收和运输能力,不论在正常和低磷条件下,BX10都比BD2具有更强的P吸收能力,BX10比BD2根系活跃面积大,但吸收动力学参数并没有优势。低磷胁迫增强了P同化到干物质,BX10增幅大于BD2。低磷胁迫下,PDJ预处理促进大豆干物质和P的积累,对根系的效果好于地上部,对BD2的效果好于BX10。PDJ预处理增加了低磷胁迫大豆根系活跃吸收面积,但吸收动力学参数并没有改善,对磷的同化效率影响也不大。二氢茉莉酸丙酯浸种可以增加低磷胁迫大豆根系活跃吸收面积、同步增强磷吸收进而增加干物质积累。
- Abstract:
- Phosphorus inefficient,including uptake and/or assimilative inefficient,is one of the most important factors which restrict the crop productivity.The P efficiency varies among crop species and varieties,and can be regulated by exogenous chemicals.In order to elucidate the mechanisms of differentia of P efficiency among varieties as guidance to crop breeding,and to evaluate the potential of chemicals application to enhance P efficiency,soybean cultivar BX10,with high phosphorus efficiency,and its contrasting variety BD2,were cultured hydroponically to investigate their P uptake and assimilative efficiency when regulated by Propyl dihydrojasmonate(PDJ).The results showed that accumulation of phosphorus and dry matter in soybean were decreased by low phosphorus with a higher extent to BD2 than to BX10.Phosphorus uptake and transportation,however,was induced by low phosphorus through increasing in root active uptake area and values of Imax and α,and decreasing in values of Km,Cmin as well as their derivative index β.BX10 showed stronger P uptake than BD2 under P stress or not,in accordance with bigger root system,especially root active uptake area.BX10 did not show a significant advantage over BD2 in uptake kinetic parameters,though a higher affinity to P occurred in BX10,indicating higher potential of uptake in extremely low P environment,the rates of maximal intake rate and transportation were actually lower.Low phosphorus facilitated phosphorus assimilation into dry matter,with a higher extent in BX10 than in BD2.Under low phosphorus stress,pretreatment with PDJ increased the accumulation of dry material and phosphorus,with a better effect on root than on shoot,and on BD2 than on BX10.PDJ increased root active uptake areas of two low P stressed soybean varieties,however,played little role in uptake kinetics and assimilative efficiency.The results concluded that pretreatment with PDJ can increase root active uptake area in accordance with increase in P uptake and dry matter.
