Theoretical and Applied Climatology, 2012
The growth and development of crops is commonly regarded as a function of time alone. However, this approach can be inadequate due to temperatures which vary from year to year caused by global climate change. This prompted the development of the growing degree day concept, which incorporates information on both the passage of time and the temperature ...

Predicting Red Pine Shoot Growth Using Growing Degree Days
Forest Science, 1985Abstract A modified Weibull function accurately described the seasonal leading shoot growth of Pinus resinosa Ait. as a function of growing degree day (GDD) sums for five seasons at one station in Minnesota. 41.4°F was a significantly better threshold temperature than the commonly cited 40°F from which to calculate GDD.

Growing degree-days for the ‘Niagara Rosada’ grapevine pruned in different seasons
International Journal of Biometeorology, 2011Plant growth and development are proportional to biological time, or the thermal time of the species, which can be defined as the integral of the temperature over time between the lower and upper temperature developmental thresholds. The objective of this study was to investigate the efficiency of the growing degree-day (GDD) approach for vines of the '

Mathematical formulae for calculating the base temperature for growing degree days
Agricultural and Forest Meteorology, 1995Much research has been done on finding methods to determine the base temperature, a very important variable in computation of growing degree days (GDD). Four common methods have been reported often in the literature: (1) the least standard deviation in growing degree days; (2) the least standard deviation in days; (3) coefficient of variation; (4 ...

Morphological Development of Alfalfa as a function of Growing Degree Days
Journal of Production Agriculture, 1994Growing degree days (GDD, base = 41 °F) may be useful for estimating alfalfa (Medicago sativa L.) morphological development (mean stage by weight, MSW) as a forage management tool. Our objective was to quantify the relationship between MSW and GDD of alfalfa in several environments and years.

Using Growing Degree Days to Predict Nitrogen Availability from Livestock Manures
Soil Science Society of America Journal, 2000Predictive tools are needed to better match N release from manure with crop demand. Growing degree days (GDD) have been successfully used to predict N release from crop residues and other amendments. A 112‐d incubation experiment was conducted at 10, 17, and 24°C to evaluate GDD (0°C base temperature) predictions of N ...
