Avaliação clonal e pós-colheita de híbridos de abacaxi ornamental

Abstract

The ornamental pineapple is a novelty for the floral market due to the exotic and colorful of the small fruit. Embrapa Cassava and Fruits has been developed ornamental hybrids to this special market. This study aimed to evaluate the response to floral induction of two of these hybrids, as well as carry out a clonal evaluation, using specific descriptors developed for this kind of assay. Another objective was to perform post-harvest trials using plastic wraps and carnauba wax in order to increase the shelf life and the quality of steam. The PL01 and PL04 hybrids presented a good response to floral induction and showed steams with a good uniformity under two evaluated cycles. The clones presented the distinctness, uniformity and stability required and essential to intellectual protection and to insert a new variety on the market. Regarding the post-harvest the PL01 and PL04 hybrids presented different times of shelf life with 14 days to PL01 (control) and 20 days to PL04 with the treatment without washing + partial wrap 8 μm. The washing procedure reduced the shelf life of the pineapple steams. The use of the full plastic wrap prolonged the shelf life of the steams independent of the washing procedure or not.Thecarnauba-based wax in concentrations of 2.5%, 5% and 10% did was not efficient to prolongthe shelf life ofstems from ornamental pineapple.
