HARVESTING DATES AND STORAGE-ABILITY OF CARROTS (DAUCUS CAROTA L.) |

| Abstract:
Despite of the fact that there already exist a great number of investigations into optimum storage conditions of vegetables (see Morris et al., 1971; Ryall et al., 1972), the results of both storage investigations as well as constituent assays are rather non-uniform often they are even contradictory. Among the possible reasons that may be responsible for this fact (such as cultivar, fertilization, sampling etc.), maturity or - in other words - the physiological condition of the test object has, by this time, not sufficiently been taken into account. Smith (1948), in a critical study, asked whether the durability of carrots might depend on the maturity stage which the roots can reach in the soil. His storage investigations showed that durability of carrots is affected by both the seeding as well as the harvesting date, yet he could not draw any conclusions for practical use. Other authors (Saburow et al., 1951; Platenius, 1934; Goris, 1969; Weichmann, 1972; Ryall et al., 1972; Phan et al., 1973; Zott et al., 1973; Fritz et al., 1974) were also involved in working on the problem of 'harvest maturity'of carrots. Their results are partly contradictory. However, it is particularly noteworthy that, so far, none of these authors had been engaged with a sequence of investigations starting with material from defined cultivation up to an analytical evaluation of the stored product. Consequently, there is a lack of realistic values as to the interrelation harvest maturity - storage behaviour - food quality. | |
