| 1 | Genetics and Molecular Marker Identification of a Resistance to Glomerella Leaf Spot in Apple显示文摘Apple Glomerella leaf spot(GLS) is a destructive fungal disease that damages apple leaves during the summer in China.Breeding new diseaseresistant varieties is considered to be the best way of controlling GLS.A genetic study of resistance to Glomerella leaf spot(GLS) in apple was conducted by using four F_1 hybrid groups(‘Fuji' בGolden Delicious',‘Golden Delicious' בFuji',‘Gala' בFuji',and ‘Fuji' בQF-2') generated from two highly resistant varieties or selections,‘Fuji' and ‘QF-2',and two highly susceptible varieties,‘Golden Delicious' and ‘Gala'.The results showed that the separation ratios of resistant plants to the susceptible ones in the four F_1 hybrid groups were statistically consistent with the theoretical ratios of 1:1,1:1,0:1,and 1:0.Comprehensive analysis enabled us to generate the following conclusions:GLS resistance in apple may be controlled by a single recessive gene.The genotype of the resistant plants was rr,whereas the genotypes of the susceptible ones were RR and Rr.By using ‘Golden Delicious' בFuji' F_1 hybrid groups and the bulked segregation analysis(BSA) method,the marker S0506206-243 bp associated with disease resistance character to GLS was identified through screening 500 SSR primers encompassing the entire apple genome with even coverage,and the genetic distance between the marker and the GLS resistance gene was 9.8 cM. | LIU Yuanxia LI Baohua WANG Caihong LIU Chunxiao KONG Xianghua ZHU Jun DAI Hongyi | 2016 | Horticultural Plant Journal2016，2，3： | 6 |
| 2 | Impact of Asarum Essential Oils on Physiological and Biochemical Indicators of Two Agricultural Pests显示文摘[Objective]The paper was to study the effects of asarum essential oils on physiological and biochemical indices of two agricultural pests. [Method]Asarum essential oils were extracted by different methods,and their effects on physiological and biochemical indices related to the structure of body wall( chitin and phenoloxidase),the physiological and biochemical indices acting on the nervous system( Acetylcholinesterase),and the physiological and biochemical indices acting on the digestive system( protease,amylase and lipase) of Ostrinia furnacalis and Mythimna seperata were studied. [Result]Asarum essential oils had no effect no chitin content of body wall under the experimental concentration,and had no inhibitory effect but activated effect on polyphenol oxidase activity. Asarum essential oils could act on the nervous system of insect,and had strong inhibitory effect against acetylcholinesterase activity of O. furnacalis larvae,with inhibition rates of 24. 86%- 38. 79%. Asarum essential oils showed a significant activated effect on pepsin activity in midgut,but the activated amplitude became smaller with the prolongation of treatment time. Asarum essential oils showed a significant inhibitory effect on activities of amylase and lipase,indicating that it could play an insecticidal effect by inhibiting activity of amylase and lipase,and it could act on digestive system of insect. [Conclusion]The study laid the foundation for further development of asarum as botanical pesticide. | Liu Yan Ji Lanzhu Wang Guiqing Wang Yuanxia Zhang Yue Yi Xuemei | 2014 | Plant Diseases and Pests2014，5，3： | 2 |
| 3 | Evolution Behaviors of Oxides in Severely Plastic Deformed Region of AISI 52100 Steel during Dry Sliding Wear显示文摘Under dry sliding wear, the evolution of oxides in severely plastic deformed(SPD) regions of metals has a great impact on the wear behaviors. To study the evolution behaviors of oxides in the SPD region, an SPD region was prefabricated on the surface of AISI 52100 steel by supersonic ?ne particle bombarding(SFPB) treatment. Dry sliding wear tests were carried out on both of the SFPB-treated and original samples.Wear volume loss of the SPBF-treated samples were compared with those of the original samples at different loads. Microstructure, element composition and oxides distribution in the SPD region were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM) and an electron probe microanalysis(EPMA). The results show that the evolution behaviors of the oxides in the SPD region change signi?cantly with the load. Under low loads, oxides are usually formed on the contact surface. It inhibits adhesive wear on the steel. However, under high loads, oxides are apt to distribute along the cracks in the subsurface layer. The internal oxidation along the cracks can accelerate the cracks propagation, resulting in severe delamination wear on the steel. | Yuanxia Lao Hao Du Tianying Xiong Yuan Wang | 2017 | Journal of Materials Science & Technology2017，33，4： | 2 |
