in order to evaluate the genetic diversity of common bean (phaseolus vulgaris l.) and the relationships between studied characteristics with seed storage proteins, 60 genotypes with three colors (white, red and pinto bean) were studied using an augmented design with three blocks and four varieties as controls. the majority of studied traits were significantly different between large and small s...

this study was conducted over a three-year period (1998, 1999 and 2000) to evaluate some drought tolerance indices and their relations with sugar yield in some sugar beet genotypes under early season drought and non-drought conditions. the experimental design was a split plot with a randomized complete block. the main plots consisted of two irrigation regimes: non-stress and water stress in ear...

objective: there has been a growing interest in finding plants with biological active ingredients for medicinal application. materials and methods: three colors of petals of althaea officinalis (a. officinalis) flowers, i.e., pink, reddish pink, and white were examined for total antioxidant activity and flavonoids content. results: the reddish pink flowers of a. officinalis have more antioxidant...

In the late thirteenth century, Theodoric of Freiberg, a Dominican monk, theologian, and physicist, performed a simple experiment: with his back to the sun, he held a spherical bottle filled with water in the sunlight. By following the trajectory of the refracted and reflected light and having the bottle play the same role as a single water drop, he gave a scientific explanation of rainbows, in...

in order to evaluate the best drought resistance indices in sugar beetgenotypes, an experiment was conducted in 2002 using a split- plot design within randomized complete block design with three replications at the research farm, shiraz-zarghan. the main plots consisted of three irrigated regimes: non stress, 75% (mid stress) and 50% (intense stress) non stress and the ten genotypes as the sub ...

Melanocortin 1 receptor (MC1R) gene plays a key role in determining coat color in several species, including the cattle. However, up to now there is no report regarding the MC1R gene and the potential association of its mutations with coat colors in yak (Poephagus grunniens). In this study, we sequenced the encoding region of the MC1R gene in three yak breeds with completely white (Tianzhu bree...

abstract this research was conducted to study the effects of different light colors on growth indices (growth rate and specific growth rate), feed conversion and survival rate in tiger barb (barbus tetazone) fish for 6 weeks. 120 fish with an average weight 75 ±0.02 were respectively divided in four groups of white, natural, green and blue colors (with three replicates for each treatment). fish...
