Genetic variability of some cultivars of pistachio tree based in composition of vitamins
Abstract
The identification and the characterisation of some cultivars of pistachio trees of the south of Tunisia were shown to have a remarkable diversity between different cultivars by using molecular markers (ISSR) supported by morphological markers [leaf length, leaf area, fruit length, terminal leaflet shape, length leaflet and chemical composition (content of vitamins)]. The content of vitamin B1 varied from zero in Kermizi, Meknessy 1, Mumtez, Mateur 2 and Mateur 3 varieties to 1.9 mg/100 g in Lybie rouge. For the vitamin B2 content, the value ranged from 0.1 mg/100 g in Mateur 3 variety to 7 mg/100 g in Lybie rouge. Vitamin B6 content varied from 0. 16 mg/100 g in Mateur 3 variety to 1.643 mg/100 g in Red Aleppo. Vitamin C vitamin content can reach 9 mg/100 g in Lybie blanc variety.
