California Avocado Society 1991 Yearbook 75:145

 

Research Update

The 1990 Yearbook included a paper, "The Effect of Minimum Temperature on Avocado Yields," by D. N. Zamet, Acco Experiment Station, Israel.

The author has since analyzed data for two additional crop years which he presents here as a figure showing the relationship between avocado yields in the Western Galilee of Israel and the number of cooling units during the main flowering period. Cooling units were calculated from the number of five day groupings with an average minimum temperature below 10 °C.

Other investigators of the effect of temperature on avocado production will find it useful to refer to the earlier paper on pages 247-256 of the 1990 Yearbook.
