A method and apparatus for electronic image processing are described. The light scanning unit includes a composite light source in which a plurality of light sources for emitting coherent light having different wavelengths are arranged adjacent to one another and an optical axis of each light source is arranged almost parallel and which emits light at a divergence angle centering on each optical axis. During the crop processing, the wheels bear on the ground, the supporting device further being provided with an element for moving, for transport of the haymaking machine, the balance arm about its pivot axis to an oblique position in which the wheel at one of the ends of the balance arm is located at some distance from the ground. The core includes a bore axially disposed within the first optical cladding layer. A tensioning member is operable to bias a movable roof member into contact with a wheel which is operable to engage with and selectively drive the roof member between positions. \u2018Sahara\u2019 is characterized by an early time of flowering, an early time of ripening, an RHS red group fruit flesh color, a terminal leaflet length to width ratio that is longer than broad, and a terminal leaflet base shape that is acute.
