دراسة توصيفيه لبعض طرز المحلب البري (Prunus mahaleb L)‎ المنتشرة في سورية

الملخص EN

This research was carried out during 2009-2010 in some Syrian governorates, Lattakia (Slenfeh), Damasccus countryside (Assal alward) Al-Sweda (Dahr elgabal), and Aleppo (Kafer genneh).

Some phenotypes of wild Mahlab (Prunus mahaleb L.) were naturally grown in the forest of those regions.

These trees are more than 50 years old, adapted with the environment of those regions, highly variable, have a strong vegetative growth and good fruit production.

In this study, 22 phenotypes were described, and later six of them which are superior in the morphological characterization were selected; their locations were determined using GPS and they were described according to International Plant Genetic Resources Institute (IPGRI) descriptor of cherry (because there is no descriptor for mahlab) with photo graphics for their trees, leaves, flowers and fruits for every type.

The statistical analysis of fruit’s weight and core/ fruit percentage was done using GenStat proggram in order to determine the least significant difference between data and the relationship among studied phenotypes.

Finally, these phenotypes classified in two groups: The First contains: (REw11, LSr7) and corrrelated with (REs1) by ratio 86%.

The second contains: (AK3, SD4) and correlated with (LSe1) by ratio 89%.

The wild phenotype (SD4) was the best in all characters.

This clearly shows that there is a correlation among studied phenotypes even though they belonged to different natural spreading sites (locations).

The correlation among the morphological traits was further proved using the statistical program SPSS.

In addition, the quanttitative results related to the morphological description exposed using the box plot of the same program.
