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 ...

Evapotranspiration Crop Coefficients Predicted Using Growing-Degree-Days
Transactions of the ASAE, 1985ABSTRACT MONTHLY evapotranspiration (Et) of alfalfa (Medicago sativa L.), cotton (Gossypium hirsutum L.), corn (Zea mays L.), and sorghum (Sorghum bicolor (L) Moench) was measured in nonweighing lysimeters for various years and locations in New Mexico to evaluate the effects of various climatic conditions.

RELATIONSHIP BETWEEN PERCENTAGE EMERGENCE AND GROWING DEGREE DAYS FOR CORN
Canadian Journal of Soil Science, 1990Seed bed temperature is often the limiting environmental factor affecting corn (Zea mays L.) emergence, particularly in short-season production areas or when conservation tillage practices are employed. In this study, observations of the percentage emergence and seed bed growing degree days (base 10 °C) are used to assess functions which model the ...

Evaluation of different methods for determining growing degree-day thresholds in apricot cultivars
International Journal of Biometeorology, 2009The aim of this study was to examine different methods for determining growing degree-day (GDD) threshold temperatures for two phenological stages (full bloom and harvest) and select the optimal thresholds for a greater number of apricot (Prunus armeniaca L.) cultivars grown in the Belgrade region.
