Aucuparia is an important slow growth forest tree with medicinal, industrial and ornamental uses which is applied for reforestation in high altitude of mountain lands. This species has been endangered at northern forests of Iran; therefore micropropagation of adult trees by bud culture may help to reforestation. The best sterilizing treatment was the buds washing with HgCl2% 0.1 solution for 7 ...

the purpose of this paper is to investigate causality relationship between emission of carbon dioxide, the level of national income and energy consumption in iran consumption of fuel fossil as an input of production or as a final consumption which produces significant amount of pollution such as green house gases in the world. c02 emission is the most important green – house gases which has the...

abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

chlorophyll fluorescence induction is a rapid and noninvasive technique for measuring photosynthetic electron transport in plants. chlorophyll fluorescence measurements were performed under greenhouse condition to characterize how the fluorescence induction curves (kautsky curve) and its parameters were affected by metribuzin in susceptible and resistant junglerice (echinochloa colona (l.) link...
