Temperature, humidity and precipitation in an area, are parameters proved influential in the climate of that area, and one should recognize them so that he can determine the climate of that area. Climate changes are of primary importance in climatology, and in recent years, have been of great concern to researchers and even politicians and organizations, for they can play an important role in s...

Objective: In this study, the levels and antioxidant activities of some secondary metabolites isolated from five pistachio (Pistacia vera)cultivars collected from four different geographical regions of Iran, were studied. Materials and Methods: Total phenolic compounds levels were determined by Folin-Ciocalteu method. Total flavonoid content was determined as AlCl3 complex and expressed as mg o...

to produce embryogenic callus and somatic embryos, tendril explants were collected and cultured in ms medium supplemented with various concentrations of hormones. after one month most of explants produced callus. the highest percent of embryogenic callus obtained in ms medium supplemented with 4.5 µm bap and 1µm 2,4-d. production of somatic embryos was depended on genotype and medium. yaghouti ...

in this research, we studied physical, chemical and biochemical characteristics of pistachio entitled pistacia vera cv. daneshmandi and was compared to three pistachio including of badami sefid, kalle ghoochi and akbari. the examined characteristics were fresh and dry weight of seed, green shell and also kernel, weight of hard shell, seedless and early opening nut, comparing the seed and kernel...

a number of grapevine cultivars have female flowers and for better fruit set, they need pollinizer. single planting of these cultivars leads to severe decrease in fruit set. this research was carried out to investigate the effect of cross pollination with four grape cultivars (askari, rish baba, bidane sefid and tabarze sefid) on fruit set, bunch weight, berry per cluster, average weight of 20 ...

Expression patterns of four candidate AREB/ABF genes and four DREB/CBF genes were evaluated in leaf and root tissues of five grape varieties ('Qalati', 'Kaj Angoor', 'Sabz Angoor', 'Siahe Zarghan', 'Bidane Safid') with differential response to drought stress. Among the AREB/ABF genes, AREB1 and ABF2 showed up-regulation in response to drought stress in leaf and root tissues of all varieties whi...

abstract to produce embryogenic callus and somatic embryo, whole flower explants were collected at two sampling stages of i, iii. to produce embryogenic callus and somatic embryo, ms medium supplemented with 5 and 10µm 2,4-d and 2µm bap were used. for embryo differentiation, ms medium with 0.5mg/l iba, ms medium without any plant growth regulators, ms medium with 2mg/l iba and 0.2mg/l bap, ms m...

sweet cherry (prunus avium l.) is considered as one of the most important temperate zone fruits worldwide. it is an economical fruit with high demand because of its early ripening fruits that enter the market early in the season. most sweet cherry cultivars are self-incompatible, not able to produce commercial fruit without being pollinated with a compatible pollinizer. in the present study, fl...
