The Cardinal Temperatures and pH Response of Thielaviopsis Basicola
Mycologia, 1955The severity of black root rot of tobacco, caused by Thielaviopsis basicola (Berk. and Br.) Ferr., is influenced markedly by soil tempera? ture and pH. Field studies by Johnson and Hartman (5) indicated the occurrence of the disease is determined primarily by soil tempera? ture. Valleau et al.

This paper addresses three issues relating to development in wheat. Whether thermal amplitude changes rates of leaf appearance and phenological development, whether the responses of leaf appearance to a wide range of temperature can be acceptably described in terms of rates and cardinal (base and optimum) temperatures, and whether similar rates and ...

Cardinal Temperatures and Thermal Time for Germination of Sarawak Traditional Rice
Malaysian Applied Biology, 2023Germination of two rice landraces, namely Bario Sederhana and Biris, was determined from twelve temperatures (12.5 – 40 ºC) in a series of incubation experiments. The cardinal temperatures and thermal time for germination were estimated from a ‘broken-stick’ linear model. Both landraces had a Tb of 10 ºC, Topt between 32 – 33 ºC, and Tmax of 43 ºC.

Surface temperature determination from borehole measurements: regularization by cardinal series
Nonlinear Analysis: Theory, Methods & Applications, 2002The authors consider the problem of recovering the temperature on the surface of a heat conducting half-plane from temperature measurements on an interior line, given the initial temperature. The problem, which is ill-posed, is regularized by truncated integration and expansion in cardinal series. Error estimates and numerical results are given, and an

Cardinal temperatures for germination and early growth of two Lesquerella species
Industrial Crops and Products, 2007Lesquerella (Lesquerella fendleri) is a potential alternative crop that is being studied for commercial oilseed production. Understanding the minimum temperatures for germination and seedling growth is important for determining potential areas for lesquerella production.

Use of the Weibull Function to Calculate Cardinal Temperatures in Faba Bean
Journal of Experimental Botany, 1990The major objective of this paper is to demonstrate not only that the Weibull function accurately models cumulative germination, but also that it can be used to calculate cardinal temperatures and thus thermal time requirement for the germination of seeds, in this case faba ...

A hydrothermal time model explains the cardinal temperatures for seed germination
Plant, Cell & Environment, 2002AbstractTemperature (T) and water potential (y) are two primary environmental regulators of seed germination. Seeds exhibit a base or minimum T for germination (Tb), an optimum T at which germination is most rapid (To), and a maximum or ceiling T at which germination is prevented (Tc).

A cardinal temperature-based phenotyping method for rice
2010Rice is one of the major food crops in the world. It is characterized by a wide diversity of growing conditions through latitude and altitude. Temperature is one of the most important factors determining plant growth, development and yield. In the context of climate change, thermal constraint (cold and chilling) could highly affect rice production.
