THE MEAN (“TYPICAL”) NUMBER OF HEAT UNITS ACCUMULATED IN ONE SEASON, Dth > 9C, Jan 1 – June 30.Notes: RANGE AND VARIANCE ARE KNOWN BUT NOT SHOWN; ELEVATIONAL GRADIENT, REDRAW WITH ELEV ON X-AXIS

ACCUMULATION OF HEAT-UNITS Dth > 9C, Jan 1 – June 30.grape = 2004; boysenberry = 2005; lemon = 2006. 2006 slow start fast finish to show the warmest spring accumulation. 2005 the coolest spring, slow start, stayed low. Moth flight reflects these data, examples TBA????
