Study on the Relationship between Fruit-Stem Separation Force and Fruit Shape of Processing Tomato

In order to provide a theoretical basis for the research on processing tomato harvester, three kinds of processing tomatoes which were largely cultivated and suitable for mechanization harvest in Xinjiang location of China were sampled, and after measuring the red-ripe fruit weight, fruit transverse and longitudinal diameter, the regression equations about the fruit weight and the fruit transverse diameter, fruit longitudinal diameter, fruit shape were established, and the fruit-stem separation force test on the samples was carried out, so the regression equations about the processing tomato fruit-stem separation force and the fruit weight were established. Finally, the mathematical models about fruit-stem separation force and fruit shape of processing tomatoes were built.
