AM and its application in plant disease prevention of Chinese medicinal herbs cultivation / 中国中药杂志

To study the beneficial effect of AMF from the utilization achievement in the agroforestry research, we discuss the application of AM in medicinal plant disease prevention and control. This paper summarized the type of medicinal plant disease, the influence of plant disease and the commonly used prevention method in production. As for the adverse consequences caused by plant's non-infectious and infectious diseases, AM has some improvement function. Something will affect the function of AM in the prevention of medicinal plant disease, for example, the relationship between AMF and the plants, the quantity, the time and the environmental factors about AMF inoculation and so on. In order to achieve the useful effect of AM in the prevention of medicinal plant disease, we should choose the suitable condition during production in practice to carry on the vaccination.

Effects of heavy metal on Astragalus membranaceus seeds germination and physiological target / 中国中药杂志

<p><b>OBJECTIVE</b>To study the effects of heavy metals on germination and antioxidant systems of the seeds of Astragalus membranaceus.</p><p><b>METHOD</b>The seeds were treated with three different heavy metals (Cu, Pb, Cd) and the germination rate, germination energy, germination index, seedling root length, seedling fresh weight, soluble protein, antioxidant enzyme systems, electrical conductivity were detected and analyzed.</p><p><b>RESULT</b>The results indicated that all of the three kinds of heavy metals had a significant effect on the seed germination index at different levels of concentrations except germinating ability. Different kinds of heavy metals could also enhance the vitality of POD and CAT, increase the electrical conductivity and the concentration of soluble protein.</p><p><b>CONCLUSION</b>It can be concluded that heavy metals have a significant effect on the growth and antioxidant system of the seed.</p>
