GOMES, JOSÉ EVERALDO; PERECIN, DILERMANDO  and  MARTINS, ANTÔNIO BALDO GERALDO. Correlations among physico-chemical characters of west indian cherry fruits with meteorological variables. Rev. Bras. Frutic. [online]. 2002, vol.24, n.1, pp.111-114. ISSN 0100-2945.

The objective of this experiment was to estimate associations among physico-chemical characters with meteorological variables from December/97 to January/99 in FCAV, Jaboticabal, SP. At every spontaneous crop of 5 genotypes, medium height and diameter of twenty fruits, vitamin C amount, Brix, pH, medium pulp profit in three samples of twenty fruits, medium meight of fruits and crop time were evaluated. Daily meteorological data were taken from the agrometeorological Department of Exact Sciences in FCAV-UNESP. Supported by the largest correlations among averages of maximum (TMAX), minimum (TMIN) and medium (TME) temperatures at the crop period (1), at the crop period plus three days before it (2) and at the crop period plus ten days before it (3) associated to the physico-chemical characters of fruits, TMIN2 was chosen as the most effective in correlated responses, and data from precipitacion (PR) and daily sunny hours (HL) in the same period (TMIN2) were comprised. With precipitacion and daily sunny hours data from TMIN2 period, correlations with physico-chemical characters of West Indian cherry fruits were measured in general average and in the average inside each genotype. It could be concluded that meteorological variables TMIN2, PR, HL showed different responses inside genotypes and influenced physico-chemical characters of fruits; HL correlation to crop time among and inside the genotypes were directly and highly significant and the variable HL influenced the periodicity and extention of crops.
