Screening of Continuous Cropping Obstacle Resistance Chrysanthemum Varieties and Study on Its Resistance Mechanism
WANG Yan;JIANG Jing;MIAO Wei-hao;Based on the flower type, flower color and flower character, 55 cut chrysanthemum varieties were selected and the disease index were recorded to degrade the resistance level of cut chrysanthemum varieties, and then the resistance varieties were selected. The results indicated that the variety Nannong Libai showed high-resistance(HR) to continuous cropping obstacle, the varieties Nannong Bingjie and Nannong Yuanlv represent medium resistance(MR) to continuous cropping obstacle, and the varieties Menghong, Nannong Doulv and Nannong Daixue showed susceptible(S) to the continuous cropping obstacle, the remaining 49 cut chrysanthemum varieties were belonging to the high-sensitivity varieties(HS),accounting for 89.1% of the total tested varieties. The disease index of HS variety Nannong Fenying was 87.5%,which was 3.69 times than a HR variety Nannong Libai, the stem height of HS variety Nannong Libai was 95.00 cm, and the stem diameter was 5.34 cm, which was 1.44 and 1.22 times than that in the S variety Nannong Fenying. In addition, the leaf enzyme activities showed the positive correlation with varieties resistance level. The PPO,PAL and POD activities of plant leaves in HR variety Nannong Libai were 201.33,36.33 and 392.67 U/(g·min),respectively, which was 1.62,1.43 and 1.23 times than that in the HS variety Nannong Fenying. The activity of hydrogenase showed positively correlated with its variety resistance level. The soil enzyme activities showed as: HR > MR HS>S, the quantity of bacteria and fungi in the rhizosphere soil of HR varieties were 2.46 × 109 and 9.73×106 copies/g in the flowering time, which were 4.24 and 0.65 times higher than that in the HS variety Nannong Fenying soil.The study showed that the resistance mechanism of different cut chrysanthemum resistant varieties to continuous cropping obstacle was mainly by enriching beneficial microorganisms, maintain higher PAL and POD activities in leaf tissue, enhances soil enzyme activities, and then maintains the normal growth of roots and stems, and thus increasing the resists ability to the infection of pathogenic fungi. The result of this study is useful to tap and utilize the potential of chrysanthemum itself to provide an elite variety reserve for chrysanthemum disease resistance breeding in the future.

Research on Micro-climate and Medicinal Plant Growth Characteristics Under Different Canopy Densities in a Forest-Medicine Intercropping Model
MA Yi-xi;WANG Dong-li;LIU Jian-hua;[Objective] By monitoring the microclimate characteristics and the growth characteristics of medicinal plants under the forest medicine model, the relationship between microclimate change and plant growth characteristics was revealed. [Method] P. sylvestris forest in Zhanggutai was taken as the research object, and the stands with canopy densities of T0.2, T0.4 and T0.6 were constructed by thinning, and the forest medicine model was constructed by combining the planting of Radix Isatidis. [Result] The results showed that there was no significant difference in temperature and humidity between the forest floor and the ground surface with different canopy density, but the light intensity gradually weakened at noon and afternoon with the increase of canopy density, and T0.2 was significantly higher than T0.6(P<0.05). The temperature and light intensity in non-shaded areas were generally higher than those in shaded areas. The number of germination and emergence of T0.4 and the plant height in seedling stage were significantly higher than those in other forest lands with canopy density(P<0.05), and the plant height, biomass and yield in peak growth stage were significantly higher than T0.2(P<0.05). And the growth of plants in shaded areas was generally better than that in non-shaded areas. There is a positive correlation between microclimate indicators and plant growth indicators, while there is a negative correlation between plant growth and microclimate. [Conclusion] When planting Radix Isatis under P. sylvestris forest, a moderate canopy density should be established, and water management should be strengthened during the germination and emergence stage of plants in dryland areas without shade.

Effect of Shading on Growth and Active Ingredients of Eleutherococcus senticosus
LI Xiang-quan;AI Zhi-qiang;LIU Ji-yun;[Objective]To explore the suitable light conditions for the growth and development of E.senticosus.[Method] Shading measures were taken to regulate the light intensity of E.senticosus,and the effects of shading on the growth and development of 2-year-old E.senticosus seedlings,as well as the accumulation of three active ingredients(eleutheroside E,syringin,isofraxidin) in roots and stems were studied.[Result]Moderate shading(transmittance of 38.29%-49.12%) could increase the height,ground diameter and leaf area of E.senticosus seedlings,and promoted the accumulation of aboveground biomass of E.senticosus.Shading had a significant effect on the syringin content in the stems of E.senticosus seedlings.The syringin content was the highest under moderate shading( transmittance 49.12%).Moderate shading was beneficial to the accumulation of syringin content in stems,but shading had no obvious effect on the syringin content in the roots.The effect of shading on the content of eleutheroside E in the root and stem was not obvious.Shading had a significant effect on the isofraxidin content in the roots and stems,with the increase of light transmittance,the change trend was opposite.However,under the condition of moderate shading( light transmittance 49.12%),the isofraxidin content was relatively high in both roots and stems.[Conclusion]Site selection and shading regulation should be paid attention to in understory planting and all-light planting of E.senticosus seedlings.Appropriate shading measures are beneficial for the growth of stems and leaves and the accumulation of active ingredients in the seedlings of E.senticosus,and are one of the key factors affecting the yield and quality improvement of E.senticosus.
Population Genetic Analysis of Eleutherococcus senticosus in Northeast China with Genotyping by Sequencing(GBS)
LI Xiang-quan;LIU Yun-wei;AI Zhi-qiang;[Objective] To effectively protect the genetic resources of Eleutherococcus senticosus germplasm.[Method]Using genotyping-by-sequencing(GBS) technology, single-nucleotide-polymorphism(SNP) site mining were identified in 120 E. senticosus individuals from four populations in Northeast China, and their genetic structure and genetic diversity were analyzed.[Result]By population evolutionary tree analysis, principal component analysis and structure analysis,combined with the geographical distribution characteristics of E. senticosus, four populations of E. senticosus were clustered into three different genetic groups.But the genetic boundaries between populations were not obvious,there were some degrees of gene exchange. Analysis of the 103 546 high-quality SNPs exposed that populations of E. senticosus in Northeast China had lower genetic diversity(Private=1 943.25,π=0.239,Ho=0.235 3,He=0.234 3),there were close genetic similarities and little genetic differences among different groups,only moderate differentiation exists between Jilin and Liaoning(Fst=0.053 2),indicating that the genetic basis of E. senticosus in Northeast China was relatively narrow,which may be due to its clonal reproductive characteristics.[Conclusion]The results not only provide molecular tools for genetic studies of E.senticosus, but also contribute to germplasm conservation and utilization in Northeast China.
