On the Correlation between the Harvest of Porphyra tenera Kjelim. in the Coastal District of Mikawa Bay and the Climatic Elements

Abstract

Correlations were studied between the annual products of dried algae (Porphyra tenera Kjelim.) per producer in the eastern part of Mikawa Bay and monthly average atmospheric temperature, rainfall and number of rainy days in Nagoya, with regard to their observations during the pericd of 17 years from 1926 to 1942. The positive coefficients of correlation were significantly found in the cases of the atmospheric temperature in December (0.576) and February (0.489), and in the case of the rainfall in March (0.846).
