Temperature variability and the yield of annual crops
TL;DR: In this article, the authors present evidence for the importance of variability in temperature for annual crop yields, and consider how the impacts of these events may be predicted, and three research needs are identified in order to provide a framework for predicting the impact of episodes of hot temperatures on the yields of annual crops.
The Influence of Temperature on Seed Germination Rate in Grain Legumes
TL;DR: Co veil et al. as discussed by the authors investigated the influence of temperature on seed germination rate in grain legumes and found that at constant temperatures warmer than 7i(G) there were negative relations between temperature and rate of germination to the maximum temperature for germination, Tm(G).

Temperature responses of developmental processes have not been affected by breeding in different ecological areas for 17 crop species
Boris Parent,François Tardieu +1 more
TL;DR: Therefore, centuries of crop breeding have not impacted on the response of development to short-term changes in temperature, whereas evolution over millions of years has, and slow evolution may be a result of the need for a synchronous shift in the temperature response of all developmental processes.

Towards the Reliable Prediction of Time to Flowering in Six Annual Crops. I. The Development of Simple Models for Fluctuating Field Environments
TL;DR: A family of photothermal responses (involving unambiguous parameters and limits) which quantify the linear, non-interacting effects of P and T not on ʃ but on 1/ʃ, i.e. on the rate of progress towards flowering.

Plant Husbandry and Management Techniques for Growing Grain Legumes Under Simulated Tropical Conditions in Controlled Environments
TL;DR: In this article, practical solutions to problems incurred in growing cultivars of cowpea, soyabean, lima bean and pigeon pea under simulated tropical conditions in controlled environments, namely, Saxcil growth cabinets in which daylength, day and night temperatures, light intensity and quality, relative humidity and CO 2 concentration are precisely controlled and can be varied over time.

The growth and development of cowpeas (Vigna unguiculata)under tropical field conditions: 2. Accumulation and partition of dry weight
TL;DR: The pattern of dry weight accumulation and partition of cowpea crops grown in Nigeria is described and there was a strong relationship between final number of pods and total plant dry weight.

Simulation of the phenology of soybeans
Peter G. Jones,D.R. Lang +1 more
TL;DR: Simulation models of three phases of soybean phenology—sowing to primary leaf, primary leaf to flower initiation and flower initiation to flowering—were generated for the soybean cultivar Lee and others and validated against phenological data obtained from date of sowing experiments conducted under field conditions.
