اثر متقابل شوري و متيل ژاسمونات بر قند، آنتوسيانين، پراكسيداسيون ليپيد و برخي پارامترهاي رشد در گياه گلرنگ(Carthamus tinctorius)

Interaction of salinity and methyl jasmonate on sugar, protein, antocyanine, lipid proxidation and some growth parameters in Carthamus tinctorius

Jasmonic acid and methyl jasmonate is linolenic acid derived cyclopentanone based compounds which are widely distributed in the plant kingdom. In this study, the effects of salinity stress and methyl jasmonate on shoot fresh weight, sugar, protein, anthocyanine and lipid proxidation in 3 varieties of Carthamus tinctorius were investigated. Plants were irrigated for two weeks with 0, 6, 12ds/m salinity sodium chloride. Plants were also sprayed with 0, 0.1, 0.5 m mol methyl jasmonate for 1 week. After two weeks, plants were harvested. Salinity and MeJA treatment reduced shoot fresh weight, anthocyanine and leaf area, but increased leaf sugar and malondealdehyde content
