COMPARISON OF SIMULATED STEM TEMPERATURES AND OBSERVED AIR TEMPERATURES WITH OBSERVED STEM GROWTH IN FOREST OPENINGS

摘要

Phenology, the study of how plant or animal developmental stages relate to the organism's surrounding climate, is a well established discipline with roots dating back more than 2000 years (Hopp and Blair, 1973). For example, correlations are often noted between budbreak or first blossom and integrated air temperature (commonly referred to as heat sums.) The underlying assumption in seeking these correlations is that biological processes proceed at rates proportional to temperature.
