  摘要：

  摘要研究了N-氯苯磺酰胺钠或氯胺-B（CAB）在碱存在下于35°氧化d-葡萄糖，d-甘露糖，d-半乳糖和d-果糖的动力学，速率=观察到k [CAB] [己糖] [HO-]。产物苯甲磺酰胺无影响，离子强度的增加使速率增加，而当介质的介电常数降低时，速率降低。研究了质子库中在H 2 O mixtureD 2 O混合物中的反应。速率以d-果糖> d-半乳糖> d-葡萄糖> d-甘露糖的顺序增加。用β347 K观察到等动力学关系，表明反应是焓控制的。

  Methods for promoting plant growth based on novel photosafening treatment regimes with glycopyranosides including glycopyranosylglycopyranosides, and aryl-a-D-glycopyranosides, and more specifically, with one or more compounds comprising terminal mannosyl-triose, optionally in the presence of light enhanced by one or more light reflecting and/or refracting members such as silicon-based substrates. Furthermore, chemical synthesis processes for the above compounds are disclosed for general application to plants. Silicate microbeads of the like are distributed over the ground or substrate in which roots of a plant are supported and planted, beneath and around a plant in a manner that light is refracted or reflected toward the phylloplane.
