التنوع الجغرافي و الشكلي عند طرز برية شكلية من الزيتون Olea europea var. sylvesris الموجودة في ثلاث موائل طبيعية في محافظة حماة- سورية

Abstract EN

An eco-eographical survey was conducted for a number of wild olive trees (Olea europea subsp.

europea var.

sylvestris growing naturally in three different habitats (Berket el- Jarras, Seghata and Fakro) at Hama province, during the 2008 and 2009 seasons.

The objective of this work was to study the geographical distribution, and the degree of convergence between the genotypes based on morphological traits of leaves, seeds and fruits.

The plant material is consisted of a random collection of 26 trees, from which 50 leaves, 50 fruits and 50 seeds were collected per tree.

The morphological characteristics were studied according to the International Olive Council methods, and a cluster analysis was carried to assess the relatedness among genotypes.

Results showed that studied trees are found in different environments reflecting the flexibility and adaptation of olive tree to the Mediterranean type of climate including at the altitude of 846 m above sea level.

These trees could be clustered into three major groups, where a significant variation existed among some of the studied characteristics.

The percentage of similarity within the first group was (95.5%), 89.5% for the second cluster and 90.5% for the the third, where fruit and seed, shape and weight, have played a major role in groups distribution.
