7. Quality of pitaya fruit (Hylocereus undatus) as influenced by storage temperature and packaging
Pitaya (Hylocereus undatus) is an exotic non-climacteric fruit that reaches its best eating quality when harvested ripe, decreasing thereafter during storage. Our objectives were to determine the best combination of storage temperature and use of perforated plastic bags to maintain the postharvest quality of the fruit. Fruits were stored at 5, 7, or 10 ºC w

10. Myxomycetes ocorrentes em microhabitates especiais em Ãreas de Floresta AtlÃntica no Nordeste do Brasil: espÃcies florÃcolas / Floricolous myxomycete biota of four Atlantic Forest conservation units in the states of Pernambuco and ParaÃba; Northeast Brazil
Studies on myxomycetes are focused mainly on lignicolous; foliicolous; and corticicolous species; and many types of substrates and environments are still unexplored. Recent research carried out in moist forests suggests high diversity of species in inflorescences of large tropical herbs. This study aimed to increase the knowledge about the Neotropical distri
