Effects of Different Treatments on Seed Germination of Zanthoxylum nitidum(Roxb.)Seed

[Objectives]This study was conducted to improve the germination rate of Zanthoxylum nitidum(Roxb.)seeds and shorten the germination period.[Methods]Different germination beds,seed soaking temperatures,seed soaking time and culture temperatures were set to study the effects on seed germination of Z.nitidum.[Results]The germination rate on the filter paper germination bed was stable and it was easy for the control of humidity.The germination rate of seeds soaked in warm water at 50℃for 24 h was about 53.33%.The germination rate of seeds cultured at 25℃was as high as 91.98%.[Conclusions]This study provides a theoretical basis for seedling breeding and large-scale production of Z.nitidum.

Study on the Microscopic Identification of Chenopodium album L.

[Objectives]This study was conducted to identify the microscopic characteristics of Chenopodium album L.[Methods]The microscopic identification method was adopted.[Results]The xylem vessels and fiber bundles of the roots are arranged into 3-4 intermittent ring belts in a concave-convex pattern,alternately with the parenchymal cell ring belts;and the xylem rays vary in width.The cross section of the stems is polygonal;there are parenchyma cells at the corners of the cortex;there are many vascular bundles of varying sizes;and calcium oxalate clusters are common in the medulla and cortex.There are 2 to 4 vascular bundles in the main leaf vein,peltate;and fiber bundles exist below the phloem.The powder is characterized by numerous clusters of calcium oxalate,which are uniform in size,sharp at edges and corners.[Conclusions]This study can provide reference for the identification and quality standard of the crude drug.
