Influência da época do ano na enxertia de pequizeiro -caryocar brasiliense cambess (caryocaraceae). Anais da Escola de Agronomia e Veterinária, Goiânia, v. 21/22, n. 1, p. 61-92, jan./dez. 1991/92.

The method used to determine the seasonal pattern was the centralized geometric moving average. As auxiliary resources for indication of patterns variation, the ordinal correlation coefficient of Spcarman was used, test equality of two variances and comparison of seasonal index amplitude applied to both periods. 1t was observed change in pattern of seasonal variation for all products having increased chiefly the amplitude of scasonal index in 1979/84 period in relation to 1974n9. The principal responsable for alteration may have been governmental interference in those markets.porAcesso AbertoArtigo
