| 1 | Research Progress on Lonicera japonica Thunb.Affected by Environmental Stress显示文摘Lonicera japonica Thunb.is widely distributed in China.It has strong adaptability to the environment and can maintain normal growth and development under a variety of stress conditions.It is commonly used as a medicine with its dry flower buds or newly opened flowers,named honeysuckle,and with both economic value and ecological application value.The research progress of L.japonica Thunb.under stress conditions such as temperature,drought,light,salt,heavy metals and diseases,pests and endophytic bacteria was reviewed,and the current research situation of the physiological and biochemical response mechanism,changes of photosynthetic fluorescence and accumulation of secondary metabolites of honeysuckle under different stresses was discussed,so as to provide a reference for deep-level exploring the resistance mechanism of L.japonica Thunb.in the future and lay a theoretical foundation for the high-quality authentic ecological cultivation of L.japonica Thunb. | Jinggang LI Longtai JU Lei ZHANG Panpan SUN Min LI Jia LI Yang LIU | 2022 | Agricultural Biotechnology2022，11，1： | 1 |
| 2 | Bioactivity Determination and Control Effect Evaluation of Three Plant Secondary Metabolites against Semiaphis heraclei显示文摘[Objective] The paper was to clarify the bioactivity of trans-2-hexenal,oregano oil and thyme oil against Semiaphis heraclei and the synergistic effect of orange peel essential oil and organosilicon on the aphidicidal activity of the three agents.[Method] With S.heraclei,the dominant species of aphids in Lonicera japonica thunb.,as the test insect,the bioactivity and control effect were evaluated by the method of leaf dipping and foliar spraying.[Result] The indoor toxicity of thyme oil was the highest,with the LC_(50) of 1.793 mg/L.Adding additives significantly increased the toxicity of the agents to S.heraclei.Among them,trans-2-hexenal+OSi,oregano oil+OSi and thyme oil+OSi had obvious synergistic effects,with the toxicity coefficients of 1.80,1.48 and 1.45,respectively.Field test showed that the corrected control effect of thyme oil was the highest after con-ventional spraying,and the toxicities of the three agents were higher than that of the control group at 7 d post spraying.Under the condition of 20%reduction of three agents and adding organosilicon,the control effect was increased by about 10% at 1 d post spraying,which was higher than that of the control group at 4 d post spraying,and reached over 98% at 14 d post spraying.[Conclusion] Thyme oil has the highest toxicity and control effect on S.heraclei.Three agents combined with organosilicon have the obvious effect of reducing the quantity and increasing the efficiency,which has the potential for further development. | Panpan Sun Luyao Huang Min Li Longtai Ju Yumeng Wu Jia Li | 2021 | Plant Diseases and Pests2021，12，4： | 0 |
