Observation on the Growth and Development Characteristics of 7 Table Grapes

【Objective】 The research aims to study the growth and development characteristics of main table grape varieties in southern Xinjiang and provide theoretical basis for improving the quality of orchard cultivation management. 【Method】 Seven table grape varieties under the same site conditions in Atushi City, Xinjiang were used as research objects. The habits, phenological period, leaf traits, flowering characteristics and fruit development dynamics were investigated. 【Result】 The results showed that the germination rate of each grape variety was between 79% and 93%, and the coefficient was basically the same, but the difference in fruit branching rate was obvious. The highest value of the centennial seedless grape was 1.21, and the fruit branching rates of Menghuan seedless grape, white Munake and Hotan red grapes were the lowest, which were 1.03; The flowering period lasted for 6-11 days; the differences of leaves of each grape variety were: specific leaf weight per unit area > leaf heavy > leaf area > leaf length > petiole length > leaf length to width ratio > petiole width > leaf width > petiole thickness; Leaf weight per unit area of Xinyu was the highest, that was 0.08, and the lowest was found in white Munake, which was 0.03. 【Conclusion】 The highest chlorophyll content in grape leaves was found in white Munake grape and the growth and development of grape fruit showed a double "S" curve and single "S" curve.
