The response of tomato genotype Cal-ji  against five salinity levels (distilled water as control, 25, 50, 75 and 100 mM) were studied at germination and early seedling stages. An experiment with conducted by using a completely randomized design (CRD) with three replications. Shoot and root length, shoot and root fresh weight, seed vigor, mean germination time, germination percentage an...

The germination responses of Hordeum ulgare seeds to saline stress caused by different salt types was studied. For this, 25 seeds of mentioned species were placed on filter paper in Petri dishes containing distilled water (control), 60, 120, 180, 240, 300, 360 and 420 mM. saline solution of NaCl, CaCl2 an KCl. The results indicated that saline levels effects were significant (P < 0.05) for seed...

this research was conducted to evaluate the role of drought stress and planting dates on seeds vigour and seedling growth of produced seeds. the experiment was performed in the research field and seed technology laboratory of the department of agronomy and plant breeding, college of aboureyhan in pakdasht in spring 2008. five canola cultivars including licord, opera, modena, elite, sarigol (in ...

Six parents of Jatropha curcas were crossed in half diallel fashion, and the F 1s were evaluated to determine the combining ability for nine germination parameters. The ratio between general combining ability (GCA) and specific combining ability (SCA) variances indicated preponderance of additive gene action for all the characters except germination percentage, time of 50% germination, seedling...

in order to study the effect of  foliar application of zinc and iron on germination of soybaen seed under different level of irrigation, an experiment was conducted in 2009 at shahrekord agricultural research center. main factor was including of four levels of drought stress as irrigation (irrigation after 60, 80, 100 and 120 mm evaporation from class a evaporation basin) and sub factor was inc...

This thesis propose an automatic algorithm for the estimation of germination time on microscopic images of Aspergillus Niger. The fungus is one of the most important producers of citric acid and catalytic enzymes where production is heavily determined by its present morphology. Study of the germination rate and how the fungi is affected by its growth factors allow for controlled regulations on ...
