Effect of aqueous extracts of Eucalyptus, Myrtus and Nerium leaves on vegetative parameter and yield and quality of wheat Triticum aestivum L.

Abstract

An experiment was conducted at Al-Mishkhab Experimental Research Station, to study the effects of water extracts (cold and boiled) of Eucalyptus, Myrtus and Nerium plant leaves on flowering parameters and yield of wheat. Extraction was done by cold water (at room temperature) and boiled water to prepare concentrations of 25% , 50%, 75% and 100% as well as the control treatment (distilled water) on some vegetative growth parameters, productivity and protein content of wheat .Results showed that boiled water extracts of Eucalyptus, Myrtus and Nerium plant leaves were superior on plant height and its leaves number, productivity and its protein content. Myrtus boiled water leaf extract gave the highest values for the above parameters compared to the other leaf extracts.It was noticed that growth parameters were inhibited with the increase in the concentration of all leaf extracts except for 25% of Myrtus leaf extract by boiled water which increase the vegetative parameters which in turn reflected in an increase in the productivity by 14.6% compared to control, with protein percentage of 12.06% .
