Abstract
We investigated whether potted culture in zucchini was efficient. The total number of flowers and female of 'Diner' significantly increased compared with 2 other cultivars. The length of the largest leaf of 'Diner' was the longest, and that of 3 cultivars in potted culture was approximately 15 cm shorter than that in open culture. The number of harvest fruits in potted culture was the most with 'Diner', and that of 3 cultivars was more than that of open culture. These results were estimated that 'Diner' was optimized in potted culture because it grew vigorously and was high yield. Additionally, it was revealed that potted culture in zucchini is effective to prevent an outbreak of soil borne disease since soil in each pot was divided. Furthermore, potted culture became available to plant closely and plant size compacted by restricted root growth compared with open culture.
