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 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...

in order to investigate the germination characteristics and cardinal temperatures of biotype alhaji pseudalhagi, a laboratory experiment was conducted randomized completely design with four replications of 25 seeds. various constant temperatures 5, 8, 10, 15, 20, 25, 30, 35, 40, 45 and 50ºc were considered. the characteristics such as percentage of seed germination, rate of seed germination, th...
متن کاملEffect 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 کاملMulti-objective optimization of two hybrid power generation systems for optimum selection of SOFC reactants heat exchangers mid-temperatures
Increasing efficiency and decreasing cost are the main purposes in the design of the power generation systems. In this study two hybrid systems: solid oxide fuel cell (SOFC)-gas turbine (GT) and SOFC-GT-steam turbine (ST); are considered. Increasing the SOFC input temperature causes thermodynamics improvement in the hybrid system operation. For this purpose, using two set of SOFC reactants heat...
