“…Tea ( Camellia sinensis (L.) Kuntze) is a perennial evergreen leaf-used economic plant. Its internal rich metabolites confer tea elegant flavors and healthy function ( Wachira et al, 2013 ). The tea taste was influenced by well-characterized non-volatile metabolites including polyphenols, flavonoids, theanine and alkaloids, and the source of tea aroma was volatile metabolites including terpenoids, phenylpropanoids and fatty acid derivatives ( Yang et al, 2013 ; Daglia et al, 2014 ).…”

Compared with traditional organic fertilizer, fermented soybean is a better fertilizer resource in tea plantations. The application of organic fertilizer is a feasible practice to mitigate the soil degradation caused by the overuse of chemical fertilizers, which can effectively regulate soil microbial communities in tea plantations. However, the effects of fermented soybean on soil microbial communities, soil metabolites and metabolites in tea new shoots have not been systematically demonstrated, and their interactions have never been studied. Here, we investigated the responses of the soil microbial community, soil metabolites and metabolites of tea new shoots to urea fertilization (UF), naturally fermented soybean fertilization (NFS) and enzymatic fermented soybean fertilization (EFS), and analyzed the relationships between soil microbes, soil metabolites and metabolites in tea new shoots. The results showed that soil bacterial communities were dominated by Pseudomonas, Romboutsia, Candidatus_Nitrosotalea and Helicobacter, and soil fungal communities were dominated by Peziza, Fusarium, Candida and Cheilymenia at the genus level. In EFS, bacterial genera (Glutamicibacter and Streptomyces) and fungal genera (Candida and Actinomucor) presented high abundances, which were correlated with soil carbohydrate and lipid including D-Mannitol, D-Sorbitol, 9,12-Octadecadienoic acid and (Z)-13-Docosenoic acid. Enzymatic fermented soybean fertilization also affected the lipid metabolites in tea new shoots. Glycerolipids and glycerophospholipids significantly increased in EFS, which positively correlated with some soil microbial communities. Besides, the application of fermented soybean fertilizer could increase the contents of TP, AP and AK, which were also important environmental factors affecting the structure of soil microbial community in tea plantation. It was concluded that fermented soybean fertilization could improve soil nutrition, regulate associated microbial communities, and positively affect lipid metabolites in tea new shoots. This study not only explores the relationships between soil microbes and metabolites in tea plants, but also provides feasible technical guidance to cultivate high-quality tea using soybean as high-grade fertilizer.

“…Признаки, обеспечивающие повышение технологии сбора чайного листа (форма куста, ширина и высота куста, прирост за вегетацию), позволяют отбирать растения с заданными параметрами -высота от 70 см до 100 см, шириной от 70 см до 110 см [9]. Очень важно, чтобы продуктивные побеги имели одинаковую высоту флешей для качественного сбора листа не взирая на способ (ручной или машинный), основным критерием отбора является дружное отрастание продуктивных побегов (флешей) и их длина [10].…”

“…While some tea cultivars tolerate high light intensity, the growth of some is significantly retarded under same light intensity. It has been reported by Wachira et al (2013) [14] that Camellia sinensis var. sinensis with smaller relatively erect dark green leaves which originated from China is hardier than Camellia sinensis var.…”

Tea is one of the most important beverage crops consumed for its antioxidant properties in many parts of the world. Growing tea in Southwest Nigeria is constrained by the warm climate occasioned by high light intensity of the area. Regulation of Light intensity (LI) is necessary for possible cultivation of tea in this area. Information on response of tea to LI in Southwest Nigeria is scanty. Therefore, field experiment was carried out in Cocoa Research Institute of Nigeria Ibadan to assess the growth of two tea cultivars, 143 and 318 under three light intensities: 100% (1.04x105lux), 65% (6.75x104lux) and 45% (4.57x104lux) achieved by using sheds of 0, 1 and 2 palm fronds layers, respectively. The experiment was laid out in randomized complete block design arranged in Split plots with four replications. Data on Number of leaves (NL), Number of branches (NB), Plant height (PH, cm), Stem diameter (SD, cm), Leaf area (LA, cm2) and Dry matter (DM, g) accumulation were obtained following standard procedures, and were analyzed with descriptive statistics and ANOVA at α0.05. Cultivar 143 performed significantly better than 318 with 88.94NL, 18.73NB, 62.99PH, 0.94SD, 2194LA and 56.38DM under 45% light intensity. The highest NL (84.07), NB (15.86), PH (68.63), SD (1.06) and LA (2885.75) was produced under 45% light, while the least was produced under 100% LI. Total DM ranged from 30.20 g/plant under 100% LI to 65.80 g/plant under 45% LI. In conclusion, optimal vegetative growth and dry matter accumulation of tea cultivar 143 was achieved under 45% LI using sheds of 2 layers of palm fronds.
