Glucosinolates are sulphur containing secondary metabolites biosynthesized by many plant species in the order Brassicales. Physical tissue or cell injury leads to the breakdown of glucosinolates through the hydrolytic action of the enzyme myrosinase, resulting in the production of compounds including isothiocynates, thiocyanates and nitriles. Derivative compounds of glucosinolates have a wide r...

first of all, in order to determine the high yielding rapeseed varieties, two field experiments were performed in 2006-2008 cropping seasons in agricultural and natural resources research center of markazi province, arak (34º 5´ n; 49º 42´ e, and 1775 m above sea level), iran. in this research, 15 winter rapeseed varieties were compared in a randomized complete block design with three replicati...

Influences on viability and germination of seeds have been studied intensively for many years, particularly for the numer-ous commercially important agricultural, ornamental, and timber species. High germinating seed lots may differ substantially in field emergence when sown at the same time in the same field, and/or may differ in performance after storage in the same environment or transport t...

We have carried out a series of calculations involving bacteria and viruses embedded in dust grains, which are ejected from our solar system by radiation pressure and travel through space to other star systems. Under many conditions this type of panspermia is impractical, primarily because the ultraviolet (UV) radiation of the present Sun inactivates the micro-organisms. However, if the organ...

This research was carried out as pod cultivation to evaluate effect of different level of zinc and cadmium on agro physiological traits of Maize via factorial experiment based on completelly randomized design with three replications along 2012-2013. The factors included different level of Zinc (Zn1=0 or Control, Zn2=15 and Zn3=30 mg.kg-1) and Cadmium (Cd1=0 or control, Cd2=10, Cd3=20 and Cd4=30...

in order to compare yield and agronomic characteristics of 38 new winter rapessed (brassica napus l.) cultivars along with okapi as check, a field experiment was carried out based on randomized complete block design during 2009-10 cropping season with three. rapeseed cultivars showed significant differences for all traits at 1 percent probability level. in this research, es betty, nk karibik, n...
