SOUZA, Adilson Pacheco de; SILVA, Andréa Carvalho da; LEONEL, Sarita and ESCOBEDO, João Francisco. Basic temperatures and thermal sum for the fig trees pruned in different months . Rev. Bras. Frutic. [online]. 2009, vol.31, n.2, pp.314-322. ISSN 1806-9967. http://dx.doi.org/10.1590/S0100-29452009000200005.
It was determined for the fig trees pruned in July, August, September and October, the most minimum and maximum basic temperatures, the thermal sum express in degree-days and the influence of the temperature in the duration of the period between the prune and the beginning of the harvest, in Botucatu - SP, from 2002 to 2006. The estimated values of minimum and maxim basal temperature were 8ºC and 36 ºC, respectively. The prune periods that presented better results in seasonal variation and productivity were August and July, and it was necessary a medium thermal sum of 1955 and 2200 degree-days.
