摘要：
To assess the adaptability of Camellia oleifera for introduction in new growth locations, this study evaluated 10 representative C. oleifera cultivars from the main areas in China where this oil-producing evergreen crop is grown. Cluster analysis, correlation analysis, and membership function analysis were used to evaluate various indices of the selected C. oleifera cultivars, including flowering phenology, cold tolerance, leaf structure, pollen characteristics, and pollen viability. The correlation analysis identified the full blossoming time, leaf palisade and spongy tissue thickness, pollen deformity rate, and pollen activity as key indices for determining the adaptability of the cultivars to new areas. The membership function analysis of the 10 C. oleifera cultivars revealed the following order of adaptability: 'XLC25' > 'Changlin4hao' > 'Ganzhouyou8hao' > 'Ganzhouyou6hao' > 'Tiechengyihao' > 'Eyou465' > 'XLC10' > 'Changlin3hao' > 'Changlin18hao' > 'QY235.' When introducing C. oleifera cultivars to new regions, the higher-ranked cultivars are more likely to be successful. The results of this study may provide a new direction for the comprehensive assessment of plant introduction and domestication potential, i.e., the assessment of the vegetative and reproductive growth, adversity resistance, and blossoming time of plants.

摘要：
Anthracnose is the most devastating disease affecting persimmon (Diospyros kaki Thunb.) cultivars in China, and is caused by the pathogen recently identified as Colletotrichum horii. In this study, the symptoms of anthracnose in persimmon fruits and trees in China, and the morphological characteristics of C. horii, were observed and recorded. Thirty simple sequence repeat (SSR) markers for C. horii were developed from the whole genome of the closely related species C. gloeosporioides, which is available from the GenBank database. After screening 30 combinations of primer pairs, six SSR markers were selected to amplify the genomic DNA of 23 isolates, to assess the degree of polymorphism and the reproducibility of the SSR markers. A total of 164 discernible bands were obtained when visualizing the amplicons by electrophoresis, 156 of which showed polymorphism. A dendrogram was constructed with FreeTree software (ver. 0.9.1.50) and the similarity coefficients ranged from 0.58-0.98. The result indicated there was genetic diversity in the C. horii population in China. There was an obvious correlation between the cluster groups and the sites from which the samples were isolated. The results of this study will facilitate a more detailed understanding of the population structure of C. horii in China.

摘要：
互叶白千层Melaleuca alternifolia是著名的药用和芳香植物(Medicinal and aromatic plants, MAPs),其松油醇-4型可以生产茶树油(Tea Tree Oil,TTO),在国际市场上供不应求。综述了松油醇-4型互叶白千层种苗栽培和离体快繁的研究进展,重点论述其生长的立地环境、种植密度、育苗扦插、组织培养、遗传改良等栽培手段,揭示了当前国内互叶白千层引种与研究中存在缺乏专用肥研制、规模化栽培较少、同属植物类型分辨不清和区域立地条件标准不够规范等问题,并对未来的研究热点和方向做出展望,如配肥、扦插、引种后性状差异性和遗传控制等方面需加强研究,因互叶白千层的两栖属性及其速生林种属性,应开展南方湿地水土保持林建设和荒山造林的种植栽培实验研究,以期为我国规模化引种栽培互叶白千层提供理论依据。
