Study on Virus-free and Rapid Propagation Technology of Artemisia selengensis sp.in Yangxin County

[Objectives]This study was conducted to culture virus-free tissue culture plantlets of mid-maturing green-stalk Artemisia selengensis sp.varieties in Yangxin County.[Methods]With bud tips of A.selengensis in Yangxin as explants and MS as the basal medium,screening and proportioning of plant growth regulators were performed to establish a virus-free and rapid propagation system for mid-maturing green-stalk varieties of A.selengensis in Yangxin.[Results]The optimal callus induction medium,adventitious shoot differentiation medium,adventitious shoot elongation medium and rooting medium for explants were MS+6-BA 1.0 mg/L+NAA 0.5 mg/L+sucrose 25 g/L+agar 7 g/L,MS+6-BA 0.1 mg/L+NAA 0.1 mg/L+sucrose 25 g/L+agar 7 g/L,MS+6-BA 0.02 mg/L+NAA 0.02 mg/L+sucrose 25 g/L+agar 7 g/L and 1/2 MS+NAA 0.05 mg/L+sucrose 25 g/L+agar 7 g/L,respectively,and the seedling rate reached more than 95%.The culture conditions were as follows:temperature(25±2)℃,relative humidity 85%,illumination intensity 3000 lx,and illumination time 14 h/d.[Conclusions]This study has important practical significance for the purification and rejuvenation and large-scale industrial breeding of Yangxin A.selengensis seedlings.

Experiment and analysis on mechanical properties of Artemisia selengensis stalk

The technology used for the storage and transportation of Artemisia selengensis is becoming increasingly important with its increasing consumption and demand;moreover,the amounts of artificial planting contribute to the challenges in Artemisia selengensis harvesting.Therefore,the mechanical property parameters of the Artemisia selengensis stalks were determined and researched to reduce the mechanical damage during harvesting,transportation,processing and storage.The Artemisia selengensis stalks were taken as the test object and a physical test method was adopted to study the impact of different positions,diameters,and directions on the mechanical properties by using the TMS-Pro texture analyzer;then,the relevant changing trends of the characteristic mechanical parameters were analyzed using statistical software.In the compression test,the compression load-deformation curve was observed and the breaking force and deformation were obtained;then,the compressive strength,elastic modulus and compression energy were computed.Next,the curve-fitting of the compressive strength and compression energy was carried out.In the shear test,the shear stress-deformation curve was obtained and the shear force,deformation,shear strength,and shear work were calculated.Then,the regression fitting of the section area,peak shearing stress and shearing work was conducted.Finally,in the last bending test,the bending stress-deformation curve,bending peak force,deformation,and bending work were obtained.Then the bending forces of other plants were tested,the results were compared and analyzed with the theoretical values,and finally the regression fittings were implemented.All the analysis results showed that Artemisia selengensis stalks can be considered to be anisotropic materials.The results also showed that the compressive strength and elastic modulus decreased with the height of stalk position,while the deformation increased.In addition,with the increase in the stalk diameter,the bending strength and fracture mechanical work increased,while the deformation decreased.The research results can provide a theoretical basis and reference for the design of the harvest equipment of Artemisia selengensis while minimizing its mechanical damage.

利用隶属函数法对不同施肥处理下藜蒿的抗寒性综合评价

在自然低温胁迫条件下,以‘云南藜蒿’为试材,测定了其在不同施肥处理下的叶片电导率、可溶性糖含量、可溶性蛋白含量、脯氨酸含量(Pro)、丙二醛(MDA)含量等7项生理指标,并进行了相关性分析。利用隶属函数法对5种施肥处理条件下的藜蒿进行了抗寒性综合评价。通过综合隶属函数值评定确定最能提高藜蒿抗寒性的处理是每公顷9400kg生物有机肥料与无机养分配施。
