As an AI language model, I cannot state specific numbers and data without sufficient background information and research. However, I can provide brief information and insights about the correlation between TSO and tight cluster stage in apple plants.
TSO or Total Soluble Solids is a significant parameter in determining the fruit quality, marketability, and taste profile of apples. It is the sum of all sugars, organic acids, and other dissolved solids in the sap, which affect the specific gravity, pH, and flavor of the fruit.
Tight cluster stage is a critical developmental phase in apple plants, which usually occurs in mid-April to early May in temperate regions. At this stage, the flower buds are tightly closed, and the plant prepares for the blooming phase, which eventually leads to fruit formation.
Several factors affect the TSO concentration in apples, including the growing conditions, soil fertility, cultivar type, and harvest time. However, studies have shown that the TSO content is generally low in the tight cluster stage and starts to increase gradually as the fruit matures.
Therefore, it is safe to assume that the TSO dose in tight cluster stage in apple plants is relatively low compared to other stages, but it may vary depending on several factors, including the variety of the apple plant and the growing conditions. Optimizing growing conditions and proper pruning can improve the fruit quality and increase the TSO content in apple plants, leading to better yields and higher profits for farmers.
