RESUMO

In Brazil losses of agricultural products during production and commercialization can reach up to 30% due to mechanical damages during harvest, transportation and storage, resulting in non-commercial quality products. The inadequate conditions of transport are related to lack of awareness of most chain segments, roads in bad conditions, drivers proper training and interruption of the cold chain. The flowers and ornamental plants sectors have been important for the Brazilian economy in the last years due to the high volume of production and trade of cut and pot flowers. Pot lilies are exposed to mechanical stress such as vibration during transportation resulting in mechanical damages in plant tissues affecting the physiological response and shelf life. The packages in which the flowers are transported and how they are handled seem not appropriate to guarantee the quality of the product. The objectives of this work are to identify the types of mechanical damages generated by vibration, during road transport simulation using oriental pot lilies `Muscadet´. A shaker was used and it was suggested a new grading criteria to judge appearance. A color change study was also performed to investigate the use of color indexes as ripeness indicator and aging. A colorimeter was used. Buds and flowers were subjected to vibration and compared to non-vibrated using 4 treatments and 20 pots per treatment. Mechanical damage was identified 24 hours after vibration. Appearance evaluation considered turgidity loss, brightness, petal color change and stem bending. Mechanical damage in the lily flowers and buds are expected to be detected together with their effect in flower blossoming and shelf life. It was concluded that vibrations do affect plant quality and that the grading scale proposed was effective in discriminating differences during storage. It is recommended to transport lily plants in the bud stage than the flower one since damage is reduced
