Analysis and evaluation of the epicuticular waxe of two breed wheat cultivar

الملخص EN

The evaluation of the epicuticular waxes and the molecular arrangement within the crystals were studied on biological and non-biological surfaces from wax platelets of leaves blades of two wheat (Triticum aestivum L.) cultivars: Inia- 66 and Uruq where collected from these two cultivars and which extracted from the oil obtained from soxhlet device extraction.

The results revealed that the concentration of wax extracted from cv.

Uruq leaves have a higher concentration of wax than Inia-66 cultivar, which means that Uruq cultivar has the superiority in protection and water lose by transpiration.

The results also revealed that the wheat leaves of cv.

Inia-66 wax contain 8 compounds and the cv.

Uruq wax was different in quality and quantity content (mixture 11 compounds) and the absence of the alkane and ester compounds group in cv.Inia-66.

These differences between two cultivars may appear in biological and physical activity mechanisms in these cultivars.
