Tea varieties play a crucial role on the quality formation of matcha. This research aimed to examine the impact of four specific tea plant varieties (Okumidori, Longjing 43, Zhongcha108, and E’Cha 1) on various aspects of matcha, including sensory evaluation, major components, color quality, volatile and non-volatile metabolomic profiles. The findings revealed that the levels of tea polyphenols, ester catechins, nonester catechins, and amino acids varied among these four varieties. Notably, 177 significant different metabolites, such as phenolic acids, flavonoids, tannins, alkaloids were identified among 1383 non-volatile compounds. In addition, 97 key aroma-active compounds were identified based on their odor activity value exceeding 1. Aldehydes, heterocyclic compounds, and ketones were closely associated with the formation of volatile metabolites. Overall, this study enhances our understanding of how different tea plant varieties impact the quality of matcha, and can provide valuable guidance for improving matcha varieties in a favorable direction.

对半夏转录组数据进行分析,设计开发SSR引物,利用筛选出的SSR引物分析不同居群间半夏的遗传多样性,为半夏分子标记辅助育种提供支撑.结果显示:筛选出的19对多态性较高的引物在17个半夏居群中共检测到49个多态性位点,具有较高的多态性;利用UPGMA作图共将17个半夏居群分为3个类群;通过分子方差分析(AMOVA)发现半夏居群内的变异达到88％,说明群体与群体间的差异相对较小,遗传变异主要来源于个体间;居群间平均分化系数Fst为0.124,居群间基因流Nm值为1.765,表明居群间能正常地进行基因交流,且居群间遗传分化受基因流的影响较大.本研究利用SSR技术开发的19对SSR引物在不同半夏居群间具有一定的通用性、多态性,能将17份半夏材料明确区分.

Schltr. ex Levl. is a perennial medicinal herb (family Asclepiadaceae) native to China and is widely distributed in many provinces including Hubei, Hunan, and Jiangsu. The roots of C. stauntonii are used as an antitussive and expectorant agent to treat human diseases (Deng et al. 2017). In June 2019, approximately 40% of C. stauntonii plants were infected in three nurseries of Tuanfeng County (30°40′N, 115°10′E), Hubei Province, China. Small, water-soaked, sunken lesions initially appeared on the base of C. stauntonii stems, and then white mycelia covered the infected stem lesions in the presence of abundant moisture. Numerous whitish to tan sclerotia developed on the infected basal stem and on soil surfaces around the infected plants. The total area affected by the disease was approximately 20 ha. Ten sclerotia from symptomatic basal stems of plants were surface disinfested in 2% sodium hypochlorite for 1 min, washed thrice with sterilized distilled water, air dried, and placed on potato dextrose agar (PDA). The cultures were incubated on PDA at 28 ± 1°C in the dark, and 10 fungal isolates were obtained. The radial mycelial growth was 16 mm/day, and numerous globoid sclerotia formed after 10 days of incubation. The diameter of mature sclerotia ranged from 0.3 to 1.5 mm (1.1 ± 0.51; n = 100). The sclerotia were initially white, turning brown and melanized with age. The white mycelium formed typical clamp connections after 5 days of growth. Aerial fungal growth was composed of many narrow hyphae 3 to 7 μm wide. Isolate was identified as Sclerotium rolfsii based on mycelial and sclerotial characteristics (Punja and Damiani 1996). For molecular identification, the strain BQ1 was chosen for DNA sequencing. The internal transcribed spacer (ITS) (White et al. 1990) and the translation elongation factor (TEF-1α) (Wendland and Kothe 1997) regions were amplified and sequenced, and the resulting sequences were deposited in GenBank (accession nos. MN915128 and MT052174). BLASTN analysis of the sequences showed 100 and 99.21% identity to S. rolfsii, the imperfect stage of Athelia rolfsii (MN622806.1 and MN106270.1). Based on morphological and molecular characteristics, the fungus was identified as S. rolfsii. BQ1 was chosen to fulfill Koch’s postulates. Ten healthy 30-day-old C. stauntonii seedlings were planted in plastic pots with a sterilized mixture of peat moss and vermiculite (3:1). Pathogenicity tests were performed by placing sclerotia of BQ1 strain on the soil surface against the plant stem (one sclerotium for each seeding). Three noninoculated plants served as controls. The inoculated and noninoculated plants then were placed in a greenhouse at 28 ± 1°C, with ambient lighting and relative humidity of 70%. By 10 days after inoculation, all inoculated plants showed symptoms identical to those observed in the field, whereas no symptoms were observed on control plants. The fungus was reisolated from all the inoculated plants and identified as S. rolfsii based on cultural and morphological features. The experiment was repeated thrice with similar results. This disease has been observed on many species of plants including Scrophularia ningpoensis, Aconitum carmichaelii, and Macleaya cordata (You et al. 2017). To our knowledge, this is the first report of southern blight caused by S. rolfsii on C. stauntonii in China. There is a need to develop effective management measures to reduce the occurrence of this disease.The author(s) declare no conflict of interest.References:Deng, A. J., et al. 2017. J. Asian Nat.

The quality of compound fertilizer, organic－inorganic compound fertilizer, organic fertilizer and bio－organic fertilizer in main tea producing areas of Hubei province was evaluated. According to the national standards of different types of fertiliz-ers, the evaluation was carried out through the three certificates of fertilizers, the inspection of packaging labels and the sam-pling inspection of fertilizers. The results showed that the qualified rate of compound fertilizer was 69.23%. The qualified rate of organic－inorganic compound fertilizer was only 27.27%. The qualified rate of organic fertilizer was 33.33%. The qualified rate of bio－organic fertilizer was 46.15%. It was suggested to strengthen government supervision, formulate relevant standards for tea plantations, and strengthen the scientific fertilization concept of tea farmers.
