We investigated the effects of rooting zone restriction with root impermeable fabric sheets on yield and fruit quality in parthenocarpic tomato cultivars, 'Kyotemari' and 'Kyoakane'. Root impermeable sheets were placed 20cm deep at widths of 30 or 45cm. Two months after planting, the height and number of 'Kyotemari' tomato clusters under rooting zone restriction were larger than the control group; the growth of 'Kyoakane' had obviously been suppressed by rooting zone restriction. Rooting zone restriction increased sugar content and suppressed individual fruit weight, especially in 'Kyoakane'. These results indicate that rooting zone restriction can be used to control growth and improve fruit quality in 'Kyotemari' and 'Kyoakane' tomatoes.
