Morphological Diversity For Two Mulberry Species (Morus Alba L.) And (Morus Nigra L.) In Some Locations In Tartous

This research was conducted during the period of 2014 - 2015 in six locations ranging from a height of between (0-500 m) in Syria, Tartous Governate in order to survey and evaluate some mulberry types belong to (Morus alba and Morus nigra). 33 types (22 of white mulberry and 11 of black mulberry) were determined for the purpose of morphological and phenological characterization and for the determination of the degree of morphological relationship between those types in addition to setting their own taxonomic keys. Morphological analysis was done based on 14 morphology characteristics (leaves, catkins, fruits) in addition to a cluster analysis for all types belongs to white and black species and for each species alone. The morphological tree for all types showed two main groups with a contrast ratio of (48%), the first group included three types belong to black mulberry, and the second group included 30 types belong to both species with a contrast ratio of (0-38%), while the morphological tree for the black species types showed a contrast ratio of (47%) and (33%) for the white specie types. The degree of morphological similarity is variable between the studied types regardless of fruits color, and the percentage of contrast among the black mulberry types is higher than white mulberry types.

The Effect of IBA (Indol-3-Butyric Acid) Dose Applications on Rooting of Hardwood and Softwood Top Cuttings of White Mulberry (Morus alba L.) and Black Mulberry (Morus nigra L.)

This study was conducted at glasshouse of Citrus and Tropical Research Department in Tartus governorate, and Olive Nursery in Latakia governorate, during 2015 to determine the influence of Indol-3-Butyric Acid (IBA) doses on hardwood and softwood top cuttings of three types of M. alba L. (B-1, B-5, KH-8) and three types of M. nigra L. (M-4, KH-9, KH-1) and one fruitless type (B-3), which spreads in different locations in Tartus, Syria. Hardwood cuttings were prepared during February from one-year-old shoots, and the softwood top cuttings were prepared during August in 2015. The cuttings were treated with different doses of IBA (1000, 2000 and 4000 ppm) in addition to the control application 0 ppm. The cuttings were planted in the glasshouses in order to root.
