Germination response of palm seeds on a two-way thermogradient plate [PDF]

open access: yesRevista Ceres, 2023
Palm trees are propagated almost exclusively by seeds and each species germinates under a certain temperature range. In this sense, the two-way thermogradient plate may be used to determine temperature limits for germination and seed response to ...

An Equation for Modelling the Temperature Response of Plants using only the Cardinal Temperatures [PDF]

open access: yesAnnals of Botany, 1999
Abstract Temperature is one of the most important factors that determine plant growth, development, and yield. Accurate summarization of plant temperature response is thus a prerequisite to successful crop systems modelling and application of such models to management.

Evaluation of Nonlinear Regression Models to Describe Seed Germination Response of Mountain Rye (Secale mountanum) to Temperature

open access: yesپژوهش‌های بذر ایران, 2017
The present study sought to evaluate the effect of different temperatures on germination and to determine cardinal temperatures (i.e., base, optimum and maximum) of Secale mountanum at temperatures of 3, 5, 10, 15, 20, 25, 30 and 35oC.

Limiting temperatures of embryo growth and seed germination of Fraxinus excelsior L. (Oleaceae): a threshold model approach

open access: yesAnnals of Forest Science, 2023
Key message We have examined thermal control for embryo growth and seed germination in European ash. Using historical data (span of 36 years) of embryo index in matured seeds, we showed that maturation is not influenced by the annual average temperature.

Predicting Germination Response to Temperature. I. Cardinal-temperature Models and Subpopulation-specific Regression [PDF]

open access: yesAnnals of Botany, 2006
The purpose of this study was to compare the relative accuracy of different thermal-germination models in predicting germination-time under constant-temperature conditions. Of specific interest was the assessment of shape assumptions associated with the cardinal-temperature germination model and probit distribution often used to distribute thermal ...

Cardinal temperatures and thermal requirements for germination of cineraria seed

open access: yesThe Journal of Horticultural Science and Biotechnology, 2000
SummaryEffects of temperature on the rate of germination, measured as the reciprocal of the time taken for half the population to germinate, were studied in cineraria cvs Cindy Blue and Cindy Dark Red. The base, optimum and maximum temperatures for germination were derived respectively as 1.6, 24.8 and 37.8°C in cv.
