“…They are located directly below the peel, but often found scattered in the flesh of the fruit, especially in the calyx. There is very little information available about the mechanisms of its formation (Ferguson & Watkins, 1989;Saure, 1996;Freitas et al, 2010) despite the numerous studies that have been conducted for over a hundred years since the existence 2 Ca in apples was published more than 30 years ago by Vang-Petersen (1980), which indicated the need to make a review of studies published in recent times on bitter pits.…”

“…The Ca content in the fruits is usually much lower than in other parts of the plant (Saure, 2005). During the growing season Ca can be translocated from the fruits to the leaves and new shoots (Vang-Petersen, 1980), thus requiring a continuous supply of this mineral. This situation leads to a decrease in the concentration of Ca which can lead to the occurrence of bitter pits.…”

“…2012 que apresentam elevada mobilidade por poderem ser transportados para os frutos via xilema e floema (Saure, 2005). Assim, o transporte de Ca é restringido pelo eventual colapso dos vasos do xilema, que ocorre nas fases avançadas do desenvolvimento de maçãs (Dražeta et al, 2004), enquanto o aporte de K, Mg e N aos frutos é contínuo, o que resulta no aumento nas relações K/Ca, Mg/Ca e N/Ca, e em frutos com maior suscetibilidade a distúrbios fisiológicos, como "bitter pit" (Vang-Petersen, 1980;Ferguson & Watkins, 1989;Argenta & Suzuki, 1994;Nachtigall & Freire, 1998;Amarante et al, 2006aAmarante et al, , 2006b, depressão lenticelar ou lenticelose Curry, 2003), escaldadura superficial (Ingle & D'Souza, 1989), pingo-de-mel , degenerescência de polpa (Vang-Petersen, 1980;Perring et al, 1985), rachadura na casca (Perring, 1984), injúria por CO 2 em atmosfera controlada (Castro et al, 2007), entre outros. Porém, Volz et al (2006) relatam que há grande diferença na suscetibilidade de cultivares de maçãs a esses distúrbios.…”

“…A análise foliar, normalmente utilizada para avaliar o estado nutricional do pomar, não apresenta boa capacidade de predição do potencial de conservação da qualidade pós-colheita em maçãs (Vang-Petersen, 1980). Para esse fim, a análise de teores minerais na polpa fresca dos frutos, cerca de três semanas antes da colheita comercial, é muito usada (Ferguson & Watkins, 1989;Argenta & Suzuki, 1994;Nachtigall & Freire, 1998;Basso, 2002) e pode ser empregada na segregação de lotes e pomares já no ato da colheita.…”
