| Red globe and Flame seedless grapes were employed as experimental materials comparing the differences in fruit quality between Pergola trellis TSC and SCO to simplify the management and production control and machinery operation. Results showed that under the condition of SCO, similarity indexes of actual value and target value in grain weight and yield of Red globe were 1.02 and 1.03 respectively, and those of Flame seedless were 0.99 and 0.98. Under the condition of TSC, Red globe similarity indexes were 0.88 and 1.31, and Flame seedless ones were 0.85 and 1.08. Soluble solid content of SCO in berry became increased by 1.1% and reducing sugar content were increased by 0.6% to 2.8%. Vc content was increased by 0.3～0.5 mg·100g-1, and branch internode number of mature plants was increased by 3～4. Pith/branch were lower by 0.1 to 0.2, and plant leaf area index was decreased by 0.6 to 0.9. Under the condition of TSC, 1～4 wire frames were dragged down, resulting a lowest place of 1.44 m for fruits. SCO frame surface between 2～5 wire sink was not obvious, and grain lowest place was 1.62 m. After the first frost strike, commodity fruit rate of SCO was 2.2 times more than TSC and loss rate was 83.3% lower than the TSC. |
