| 1 | Research Progress on the Effect of Light on Plant Growth显示文摘Light is one of the important factors affecting plant growth and has an important impact on plant growth and development.In this paper,the effects of light on plant growth,development,and physiological and biochemical functions were reviewed from three aspects:light intensity and light quality on plant biomass,photosynthesis,and chemical components. | Xuejing DONG Liba XU Miao ZHANG Ying WANG Hua ZHU | 2022 | Agricultural Biotechnology2022，11，3： | 0 |
| 2 | Safety Limit Test of Heavy Metals and Pesticide Residues in the Zhuang Ethnic Medcine Herba Polygoni Chinensis from 13 Producing Areas显示文摘[Objectives]This study was conducted to determine the contents of such five heavy metals as lead(Pb),cadmium(Cd),arsenic(As),mercury(Hg)and copper(Cu)and the contents of nine kinds of organochlorine pesticide residues including total BHC(α-BHC,β-BHC,γ-BHC,δ-BHC)and total DDT(pp-DDE,pp-DDD,op-DDT,pp-DDT)and pentachloronitrobenzene in the Zhuang medicine Herba Polygoni Chinensis from 13 producing areas.[Methods]The five heavy metals were determined in accordance with the second method of general rule 2341,the inductively coupled plasma mass spectrometry method,in part 4 of the 2020 edition of Chinese Pharmacopoeia;and the nine organochlorines were determined in accordance with the first method of general rule 2341,organochlorine pesticide residue determination method(chromatography),in part 4 of the 2020 edition of Chinese Pharmacopoeia.[Results]In the Herba Polygoni Chinensis from 13 origins,the lead contents were in the range of 0.50-3.28 mg/kg;the cadmium contents were in the range of 0.06-4.21 mg/kg;the arsenic contents were in the range of 0.16-6.9 mg/kg;the copper contents were in the range of 10.5-45.1 mg/kg;the mercury contents were in the range of 0.00-0.003 mg/kg;and the nine organochlorines including the total benzene hexachloride(α-BHC,β-BHC,γ-BHC,δ-BHC),total DDT(pp-DDE,pp-DDD,op-DDT,pp-DDT)and pentachloronitrobenzene were all not detected.Referring to part 4 of the 2020 edition of Chinese Pharmacopoeia,the Cu and As of the Herba Polygoni Chinensis produced in Hezhou exceeded the standards,the Cu of the Herba Polygoni Chinensis produced in Wuzhou exceeded the standard,and the As of the Herba Polygoni Chinensis produced in Yulin City and Guilin City exceeded the standard.[Conclusions]This study provides safety limit test data for the development and utilization of Herba Polygoni Chinensis of the Zhuang medicine. | Fengfeng XIE Anda WEI Liba XU Hua ZHU Guodong HUANG Shiyan HE Linmiao LI | 2021 | Agricultural Biotechnology2021，10，3： | 0 |
| 3 | Research Progress of Dendrobium officinale Kimura et Migo显示文摘The effects of light on the quality and related genes of Dendrobium officinale were summarized, and the main chemical components and pharmacological effects of D. officinale were analyzed. The biomass accumulation of D. officinale is related to light quality and light intensity. Monochromatic light quality can make polysaccharide accumulate, and mixed light quality can promote cell proliferation and component accumulation of D. officinale. Under different light intensity, the polysaccharide content of D. officinale is different, and it changes with the change of light intensity. When a certain intensity is exceeded, the polysaccharide content decreases with the increase of light intensity. The chemical components of D. officinale are polysaccharides, alkaloids, amino acids, volatile components, etc. The analysis of the growth and components of D. officinale provides reference and basis for improving the quality and chemical components of D. officinale and promotes the research and development of related products of D. officinale. | Ying WANG Miao ZHANG XueJing DONG Liba XU Yongpeng WEI Hua ZHU | 2022 | Agricultural Biotechnology2022，11，5： | 0 |
