MetadataShow full item record
Morphological growth abnormalities were pursued and studied in field-grown alfalfa (Medicago sativa L.) in Al-Kharj agricultural area, south east of Riyadh. Significant differences between normal and abnormal plants were observed in branch length, number, leaf area, plant dry weight, and protein as well as chlorophyll content. Diseased plants showed significant decrease in chlorophyll a, and changes in protein profiles, which indicates the involvement of viral etiology.
