“…Tea can achieve high quality only when it grows in the suitable environmental conditions of light temperature, humidity, soil, and fertilizer [ 3 ]. When the light intensity exceeds 3.7 J/cm 2 ·min, the photosynthetic rate of tea leaves will decline, and the optimal temperature for the growth and development of tea new shoots is at 20–25 °C, more than this temperature range, the new shoots growth rate slows down [ 24 ].…”

“…The quality of Xiaobai white tea is determined by the fresh-leaf quality and the tea-making process, fresh-leaf is the foundation. Environmental factors, such as temperature, humidity, light, and rainfall were closely related to the growth and development of tea plants and the accumulation of fresh leaf components [ 3 ]. Tea plants grow well in conditions of 80% relative humidity and cloudy conditions (sunshine percentage ≤40%) [ 4 , 5 ].…”

“…N and P are mainly involved in the synthesis of amino acids, vitamins, chlorophyll, and other substances, and directly regulate the content and proportion of biochemical components of the tea plants [ 10 , 11 ]. K helps to promote the growth and development of tea seedlings and the absorption capacity of tea roots, thus enhancing the resilience of tea plants [ 3 ].…”

Understory planting affects the growth environment of tea plants, regulating the tea plant growth and the formation of secondary metabolites, which in turn affects the flavor of Xiaobai white tea. The present research adopted biochemical composition determination, widely targeted volatilities (WTV) analysis, multivariate statistical analysis, and odor activity value (OAV) analysis to analyze the characteristics in the macro-composition and volatile compounds of understory white tea. The sensory evaluation results indicated that understory Xiaobai white tea (LWTs) was stronger than ordinary Xiaobai white tea (PWTs) in terms of the taste of smoothness, sweetness, and thickness as well as the aromas of the flower and sweet. Understory planting reduced light intensity and air temperature, increased air humidity, organic matter, total nitrogen, and available nitrogen contents, which improved the growth environment of tea plants. The phytochemical analysis showed that the water-extractable substances, caffeine, flavonoids, and soluble sugar contents of understory tea fresh-leaf (LF) were higher than those of ordinary fresh-leaf (PF). The phytochemical analysis showed that the free amino acids, theaflavins, thearubigins, water-extractable substances, and tea polyphenols contents of LWTs were significantly higher than those of PWTs, which may explain the higher smoothness, sweetness, and thickness scores of LWTs than those of PWTs. The 2-heptanol, 2-decane, damasone, and cedar alcohol contents were significantly higher in LWTs than in PWTs, which may result in stronger flowery and sweet aromas in LWTs than in PWTs. These results provide a firm experimental basis for the observed differences in the flavor of LWTs and PWTs.

“…And tea plants survive habitats that satisfy their certain eco-physiological requirements. It is reported that tea plants require an ecological condition with temperature ranging from 13-26°C, a minimum annual rainfall of 1500-2000 mm and an average optimal relative humidity more than 70-75%, as well as acidic soil (optimal pH: 4.5-5.5) and elevation below 2000 m (Zhao et al, 2022;Ran et al, 2023). And apart from these abiotic requirements, insect pests are considered as another important factor restricting the growing of tea plants.…”

Habitat suitability analysis using species distribution models (SDMs) presents a valuable approach for determining appropriate land utilization strategies and crop planting decisions, which are vital to achieve optimal agricultural productivity and ensure environmental sustainability in the context of rapid global change. Aside abiotic conditions, pests emerge as the most important biological factor affecting crop growth. It can be an effective avenue to comprehensively assess land use suitability by building and integrating SDMs for both crops and their pests. Using the MaxEnt model and a bivariate map, we predicted and integrated the habitat suitability of tea (Camellia sinensis) and its primary insect herbivore (Empoasca onukii) in China. Our study explicitly revealed spatial heterogeneity in suitability between the two species, despite finding that they shared common environmental predictors (i.e., temperature, elevation, and soil pH). Results support South China and Southwest China as the most favorable areas for tea cultivation, while highlighting the adverse climatic challenges on tea growth in the middle and lower reaches of the Yangtze River and in the northern regions of the Yangtze River. Meanwhile, analyses emphasize the necessity of sustainable leafhopper management strategies in the middle and lower reaches of the Yangtze River and in regions along the southeast coast. These findings demonstrate the significance of comparative analysis on the habitat suitability of both crops and insect herbivores, providing valuable insights for agricultural production planning and sustainable pest management. Furthermore, the methods employed in this study hold potential for the application in diverse context, ranging from the control of invasive species to the conservation of endangered biodiversity.
