Estimation of Cardinal Temperatures for Tomato (Solanum lycopersicom) Seed Germination Using Nonlinear Regression Models
Extended Abstract Introduction: Seed germination is one of the most important factors which determine the success of failure of crop establishment. In the absence of other environmental limiting factors such as moisture, temperature would determine the rate and overall seed germination. This research was conducted to investigate the effect of temperature regimes on seed germination, quantify t...
متن کاملdetermination of cardinal temperatures and thermal time requirement during germination and emergence of chickpea genotypes (cicer arietinum l.)
determination of cardinal temperatures during seed germination and emergence as well as the thermal time requirement for each stage is essential in crop management and modeling of plant growth and development. two experiments were conducted to predict cardinal temperatures and thermal time requirement for germination and emergence of chickpea genotypes. in the first experiment, seed germination...
متن کاملCardinal temperatures for seed germination of three Quinoa (Chenopodium quinoa Willd.) cultivars
Quinoa (Chenepodium quinoa Willd.) is a grain-like crop which has a high potential of crop yield under arid environments. The objective of this study was to evaluate the responses of seed germination rate and percentage to temperatures and estimate cardinal temperatures in three quinoa cultivars (i.e., Sajama, Titicaca and Santamaria). Germination of quinoa seeds were daily counted at the tempe...
متن کاملA hydrothermal time model explains the cardinal temperatures for seed germination
Temperature ( T ) and water potential ( y ) are two primary environmental regulators of seed germination. Seeds exhibit a base or minimum T for germination ( T b ), an optimum T at which germination is most rapid ( T o ), and a maximum or ceiling T at which germination is prevented ( T c ). Germination at suboptimal T can be characterized on the basis of thermal time, or the T in excess of T b ...
متن کاملcardinal temperatures, response to temperature and range of thermal tolerance for seed germination in wheat (triticum aestivum l.) cultivars
understanding the seed germination response of cultivated genotypes to temperature is important, agronomically. the genotypes that germinate in lower temperatures could be useful for situations (such as late winter plantings) where temperatures are low in germination stage. therefore, this experiment was conducted to study the cardinal temperatures, response to sub- or supra-optimal temperature...
متن کاملevaluation of sesame cultivars germination on response to temperature: determination of cardinal temperatures and thermal tolerance
the aim of this study was to evaluate germination of different sesame genotypes on response to temperature. heat and cold tolerance indexes were determined using cardinal temperatures and evaluations of genotypes were conducted to tolerate high or low temperatures using determined indexes. in order to, germination tests were conducted in fixed temperatures incubators with 10, 15, 20, 25, 30, 35...
