tomatoes (Lycopersicon esculentum Miller cv Unicorn). Tomatoes were grown in soil and 3 kinds of hydroponics
methods using peatmoss, rockwool, and deep flow culture; supplied with the nutrient solutions of the Japanese
horticultural experiment station. Light red maturity stage tomatoes were harvested and packaged with perforated film
(ø 6 mm, 18 hole/m2) for storage at 11℃ with 85% relative humidity. The tomatoes have grown in soil depict
higher average fruit weight than other cultural methods and presented the highest firmness at the harvest time (0 day)
and after storage (16th day). The tomatoes growing in rockwool and peatmoss displayed higher soluble solids (°Brix),
vitamin C and titratable acidity (% citric acid), respectively at the harvest time and after storage compared to other
cultural methods. The respiration rate established higher in rockwool, followed by deep flow, soil, and peatmoss
cultural method and it was decreased after storage in all treatments. The ethylene production rate pointed the same
as a trend of respiration rate; deep flow culture and rockwool treatments indicated the highest ethylene production
rate at the harvest time and after storage, but it decreased during storage as maturity advanced. As a storage period
progressed, the fresh weight loss of tomatoes increased but did not exceed 1%. Therefore, for producing high quality
fruits that have the high soluble solids, tomatoes may be cultivated in rockwool and peatmoss hydroponics methods.
And for long-term storage, the tomatoes have grown in soil may be proper because the firmness of soil treatment
expressed the highest at the harvest time and retained after storage.
