Mean values for 1981-83 were SS: 4.3, 4.4, 4.5%; TA: 7.7, 8.4, 8.1 meq; EC: 661, 653, 651 μS; Hunter a/b: 0.94, 0.95, 0.95; firmness: 2084, 2438, 2525 g respectively. Corresponding values for percentage coefficient of variation (CV) were SS: 8, 8, 8; TA: 12, 12, 11; EC: 9, 11, 10; colour: 34, 29, 29; firmness: 20, 17, 20. The values for titratable acidity and electrical conductivity declined during the season while mid-season fruit was reddest and the least firm. Inter-box variation was greatest for fruit colour and firmness. Within-box variation for fruit firmness was greatest in 1981 with 46% of the boxes (samples) having CV values above 20% compared with 13 and 16% of the boxes in 1982 and 1983.||Type of material:||Journal Article||Publisher:||An Foras Talúntais||Keywords:||Seasonal variation;Irish tomatoes||Language:||en||Status of Item:||Peer reviewed|
