Quality changes during cold storage of tomato fruits drown in different substrates

1st International Symposium on Solanacea for Fresh Market -- MAR 28-31, 1995 -- MALAGA, SPAINWOS: 000071774700022Tomato plants (cv. Fantastic F-1) were grown in soilless culture on nine different growing media: perlite, spent mushroom compost, volcanic tuff, perlite + spent mushroom compost in 3 different ratios (3:1, 1:1, 1:3), and spent mushroom compost + volcanic tuff in 3 different ratios Harvested tomatoes grown on different media were cold stored at 10 degrees C and 85-90% relative humidity to determine the effect of growing medium on cold storage life. During the storage, weight losses, fruit firmness, total soluble solid content, titratable acidity, and ascorbic acid content were investigated. There was no significant difference in total soluble solid content and titratable acidity among growing media. The weight losses of fruits were higher in volcanic tuff (5.51) than in the other media. Firmness of fruits in spent mushroom compost (3.42 kg) and spent mushroom+volcanic tuff (3:1 ratio) (3.25 kg) was higher than other in the media. Ascorbic acid content was higher in fruits of spent mushroom compost+volcanic tuff (1:1 ratio) (24.73 mg/100 ml) than in the other media.Int Soc Hort Sci, Spanish Soc Hort Sci, Consejo Super Invest Cient, Junta Andalucia, Consejeria Agr & Pesca, Plan Nacl Invest Cientif & Desarrollo Tecnol, Excma, Diputac Malaga, British Council, Cajas Rurales Granada & Malaga, Unicaja, MSD Agvet, Haifa Chem, Ferquis
