تأثير رش Nicotinamide و Brassicasterol في محتوى أوراق الجرجير Eruca sativa Mil. من بعض المواد الكيموحيوية

Abstract EN

A filed experiment was conducted during the growing season of 2010/2011 to examine the effect of spraying with Nicotinamide at concentrations 0, 25 and 50 mg.L-1 and Brassicasterol at concentrations 0, 50 and 100 mg.L-1 and their interactions for two cutting of Eruca sativa Mil.

This is to predict the improved prospects of leaves contents of some biochemical constituents by measuring growth parameters (the number of leaves, total chlorophyll, fresh and dry weights, and leaves yield) and leaves content of biochemical constituents (percentages of carbohydrates, oil, protein, glucosinolate, glutathione, total phenolics, and total flavonoids).

Results showed that Nicotinamide at (50 mg.L-1) affected significantly all parameters for both cuttings, and Brassicasterol at (100 mg.L-1) affected significantly growth parameters and leaves contents of carbohydrates, oil and glucosinolate.

Brassicasterol (50 mg.L-1) treatment showed superiority in leaves content of biochemical constituents except for glucosinolate at both cuttings.

The results also indicated that interaction of Nicotinamide at concentration of (50 mg.L-1) with Brassicasterol at concentration (100 mg.L-1) produced the highest means for growth parameters, carbohydrates, oil and glucosinolate.

Nicotinamide at concentration of (50 mg.L-1) with Brassicasterol at concentration of (50 mg.L-1) gave the highest increased in protein, glutathione, total phenolics and total flavonoids, The 1st cut demonstrated the superiority in growth parameters, carbohydrates, oil and glucosinolate, and the 2nd cut superscript in protein, glutathione, total phenolics, and total flavonoids.
