Effect of Temperature and Light on Germination Characteristics of Japanese Morning Glory (Ipomoea nil): Determination of Cardinal Temperatures of Germination
DOR: 98.1000/2383-1251.1398.6.115.11.1.1575.1610 Extended Abstract Introduction: In recent years, Japanese morning glory has been recognized as a new weed in some soybean cultivation areas in the Province of Golestan. Japanese morning glory, an annual herbaceous plant, belongs to Convolvulaceae family. Germination is the first step in the competitiveness of a weed in an ecological niche. ...
متن کاملEstimation 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 کاملEstimating the cardinal temperatures of germination for Ipomoea hederaceae and Cleome viscosa at constant and alternating temperature conditions
Extended abstract: Introduction: Reports indicate the invasion of two species of Ivy-leaved morning-glory (Ipomoea hederaceae Jacq) and Asian spider flower (Cleome viscosa L.) to summer crops fields such as soybeans in Golestan province. Considering the importance of knowing the cardinal temperatures of germination in the models for predicting the presence of weeds and consequently designing c...
متن کاملPredicting germination response to temperature. I. Cardinal-temperature models and subpopulation-specific regression.
BACKGROUND AND AIMS 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 coefficients among seed sub...
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...
