To understand the adaptability and ion regulation mechanisms of Medicago sativa, Melilotus officinalis, and Astragalus adsurgens seeds at their germination stage to saline environment, the seeds were treated with different concentrations of NaCl, and their germination rate and recovery germination rate ere determined. In the meantime, the changes of main ions contents in seed embryos and the water uptake by the embryos at 400 mmol L^(-1) of NaCl were investigated.

试验对3种豆科牧草紫花苜蓿、草木樨、沙打旺的种子，在萌发阶段对盐渍环境的适应性和离子调控机制进行了研究，测定了盐渍环境中种子的萌发率和恢复萌发率；同时，对400mmolL^(-1)NaCl处理后，种子恢复萌发、胚的主要离子含量变化、水分吸收等情况进行了测定。

Paper electrophoresis showed that the Onobrychis viciaefolia and Medicago sativa cell line transformed with A〓 synthesized agropine and mannopine, and Onobrychis viciaefolia cell line transformed with LBA9402 Bin19 only synthesized agropine.

红豆草转化系获得再生植株。LBA9402 Bin19转化系可以抗100mg／l卡那霉素。苜蓿A4转化系未能得到再生植株。纸电泳分析表明红豆草A4转化系和苜蓿A〓转化系可以合成农杆碱和甘露碱，而红豆草LBA9402Bin19转化系只能合成农杆碱。

Purified GO had a molecular weight between 145, 000 and 162, 300, as determined by Sephadex G-200 filtration and SDS-PAGE of the enzyme as cross-linked with glutaraldehyde. This result showed that the holoenzyme was a tetramer, and no change occurred in molecular weight of the enzyme during the s〓orage. The active form of GO from brassica leaves showed a constant molecular weight during purification, so did that from O. sativa leaves during greening of etiolated seedlings, maybe acting as a stable tetramer.

用Sephadex G-200胶过滤和戊二醛交联后的SDS-PAGE法测得纯化的菜心叶片GO的分子量在145，000-162，300间，为四聚体；并且在放置过程中其分子量和聚合态均保持不变，为稳定的四聚体；进一步研究表明菜心叶片GO在纯化过程中和水稻叶片GO在黄化苗的转绿过程中，两种GO活性状态的分子量和聚合态也没有发生变化，均呈四聚体。
