Plants undergo a major physiological change as they transition from vegetative growth to
reproductive development. This transition is a result of responses to various endogenous …

Since 1730 when Reaumut introduced the concept of heat units, many methods of
calculating thermal physiological time heat have been used to simulate the phenology of …

This rigorous yet accessible text introduces the key physical and biochemical processes
involved in plant interactions with the aerial environment. It is designed to make the more …

Heat units, expressed in growing degree-days (GDD), are frequently used to describe the
timing of biological processes. The basic equation used is GDD=[(T MAX+ T MIN) 2]− T …

What is addressed as growing season in terrestrial ecosystems is one of the main
determinants of annual plant biomass production globally. However, there is no well …

A method is presented for estimating heat accumulation by using daily maximum and
minimum temperatures and assuming the sine curve as an approximation of the diurnal …

The state of a plant is determined by both growth and developmental processes. This
chapter provides insight into the value of using temperature for predicting plant development …

(1) The dates of budhurst of lateral shoots on 2-to 10-year old trees of Picea sitchensis were
recorded on fourteen occasions at sites near meteorological stations in lowland and upland …

High temperatures are associated with reduced crop yields,, and predictions for future
warming have raised concerns regarding future productivity and food security,,,,. However …

The objective of the CERES crop simulation models is to predict the duration of growth, the
average growth rates, and the amount of assimilate partitioned to the economic yield …
