In the period 2002-2004 have been studied 131 Jujube types in the experimental orchards of Agricultural Institute in Skopje. They are progeny derived from six varieties of Jujube: Zu tao czao, Da baj czao, Kitajski 2A, Wild midleasiatic jujube type, Ja czao, Vahshski 45-2. The seeds of these varieties were obtained by open pollination. Studies were done on the 7-9 aged plants in full fertility. Characteristics of fruits, fruit dimensions and mass of fruit were determined. It was established that the variety Kitajski 2A has the largest fruits (13.1 g). The progeny of the same variety (Kitajski 2A) is characterized with the largest fruits (8.9 g), and the progeny of the variety with the smallest fruits between varity-mothers - Da baj czao is characterized with the smallest fruits (6.3 g). The type 21/6 has an average the largest fruits (22.2 g), while the smallest are the fruits of the type 16/4 (1.8 g). The fruits from type 21/6 are bigger than fruits of the biggest Jujube variety introduced in R Macedonia -Ta jan czao.

This work evaluated the influence of different biostimulators (IBA and NAA) on rooting softwood and hardwood cuttings from some stone fruit rootstocks (

The morphological characteristics of fruits and leaves of ten Greek Strawberry tree (Arbutus andrachne L.) genotypes located on the middle course, from the left side of Konjska River, in South part of Republic of Macedonia are investigated. Among the investigated characteristics of Greek Strawberry tree genotypes it is noted a large level of polymorphism. The genotype 2 is characterized with twice as big fruit mass (1.87 g) as most of other investigated genotypes. The genotypes 2, 7 and 9 are included in the group with large fruits. According to CIELab color system the fruit skin of genotype 2 is characterized with unusually dark red coloration (L* 21.02; a* 18.8; b* 12.0), while the most attractive are the fruits from the genotype 9 (L* 23.9; a* 28.3; b* 17.4). The investigated genotypes show differences in the fruit anatomy, especially the genotype 7 which is characterized with significantly higher value for lobedness degree, pericarp area and pericarp thickness, percent of pulp and number of seeds in fruit. Large differences in the leaves dimension and form are also determined.

The pomological characteristics of five varieties and one wild form of jujube progenies were examined in the experimental orchard of the Institute of Agriculture in Skopje during [2002][2003][2004]. The seeds from the varieties: Zu tao czao, Da baj czao, Kitajski 2A, Ja czao, Vahshski 45-2, and Wild midleasiatic jujube type were obtained by open pollination. Some characteristics of the fruits such as: mass of the fruits (g), fruit density (g/cm 3 ), mass of the seed (g), and randman (%) were investigated in 7-9 years old jujube seedlings grown from that seed material and planted in the frames of a breeder field. A dominant mother effect in the inheritance was registered in the mass and density of the fruits. For instance: the variety Kitajski 2A and the types from its progeny were characterized by the greatest mass of the fruits, while, the greatest density was found in the fruits of the variety Da bai czao and the types from its progeny. The greatest mass of the seed was recorded in the variety Kitajski 2A, while the biggest average mass of the seeds was characteristic for the progeny of the Ja czao variety.
