Chilling as a factor in crop location with particular reference to deciduous orchards in California

Creator:

Aron, Robert Henry

Abstract:

Several empirical formulas that may be used to estimate available chilling are presented in this study. Many climatic parameters were considered in the derivation of these formulas. One equation employing only maximum and minimum temperatures had a coefficients of correlation (R) and R² values of .978 and .957, respectively. This...
