The results obtained from comparison with these varieties in adapting the tomato fruits for transport, were summarized below. 1. The results of investigation on the character of tomato fruits concerned with transport. The investigation was carried out from the viewpoints of the fresh weight of fruits, the size of calyxes, the thickness of epidermis, the resistability of fruits under pressure, the hardness of sarcocarp and distribution ratio of sarcocarp in a fruit. The relations between these characters and the adaptabilities for transport were, however, not clear. 2. The results of vibrating experiments. The damages of the fruits were caused increasingly as the vibrational amplitude, frequency and duration of fruits were increased, respectively. There are apparent differences in damage among these varieties, namely, the varieties which sustaind severe damage were H.1350, E.S.58 and Taiho. On the contrary, those which sustained slight damage were Roma, H.1370 and E.S.24. 3. The results of dropping tests. There are apparent discrepancies of damage among these varieties, the longer the distance of dropping fruits is, the larger the fruit's damage is. The varieties which sustained severe damage were Taiho, E.S.58 and H.1350, those which sustained slight damage were Roma, E.S.24 and H.1370. 4. The results of transporting experimens of fruits with a truck. The varieties which sustained severe damage were H.1350 and Taiho, those which sustained slight damage were Roma, H.1370 and E.S.24. In our limited experiments, we recognized that Roma, H.1370 and E.S.24 (determinate type varieties) used as an aim of proccessing were superior to H.1350 (determinate type variety) and Taiho (indeterminate type variety) having two aims of both processing and fresh vegetables in transporting fruits., Article, 信州大学農学部紀要 7(2): 93-101(1971)}, pages = {93--101}, title = {無支柱栽培トマトの加工適性に関する研究(第2報)輸送適性について}, volume = {7}, year = {1971} }
