Uticaj dužine rezidbe na masu grozda stonih sorti vinove loze

Each grapevine variety has specific pruning requirements to ensure optimal grape yield and quality. The main objective of this paper is to examine the impact of pruning severity on cluster size in table grapevine varieties under conditions of the Kozara wine-growing region. The research was conducted on the grapevine varieties ’Lasta’, ’Karmen’, ’Palatine’, ’Esther’,’Muscat Saint Vallier’ and ’Chasselas rose’. Cluster position on the fruiting shoot developing from both the spur and the cane,cluster weight and number of clusters per node were analyzed. Moving node position away from the base of the fruiting shoot results in reduced cluster size in ’Lasta’, ’Karmen’, ’Palatine’, ’Esther’ and ’Chasselas rose’, and in increased cluster weight in ’Muscat Saint Vallier’. A significant correlation was observed betweencluster weightandcluster position onthe fruiting shootin ’Lasta’, ’MuscatSaintVallier’and ’Palatine’.Svaka sorta vinove loze zahteva određen način rezidbe kako bi se dobio odgovarajući prinos i kvalitet grožđa. Osnovni cilj rada predstavlja ispitivanje uticaja dužine rezidbe na veličinu grozda stonih sorti vinove loze u uslovima Kozaračkog vinogorja. Istraživanje je obavljeno na sortama Lasta, Karmen, Palatina, Esther, Muscat St. Vallier i Chaselas rose. Kod ispitivanih sorti analizirana je pozicija pojave grozda na rodnim lastarima kondira i luka, njihova masa i učestalost pojave grozda na nodusima. Udaljavanjem pozicije nodusa od baze rodnog lastara, dolazi do smanjenja krupnoće grozda kod sorti Lasta, Karmen, Palatina, Esther i sorte Chasselas rose, a kod sorte Muscat St. Vallier do povećanja mase grozda.Utvrđena je značajna zavisnost mase grozda i pozicije pojave grozda na rodnom lastaru kod sorti Lasta, Muscat St. Vallier i Palatina

THE CHARACTERISTICS OF FRUITFULNESS OF SOME INTERSPECIES GRAPEVINE CULTIVARS

The results of important agro-biological and technological characteristics of three grapevine interspecies cultivars (Medina, Gecej Zamatos, and Kristala) are presented in this study. The following parameters were monitored: the total number of developed shoots, the number of fertile shoots, the number of bunch per vine, grape yield, fertility coefficient, the average bunch weight, yield per hectare, bunch and berry structural indicators and grape quality expressed through the content of sugar in must. Statistically significant differences were determined between the examined varieties regarding following characteristics: the number and yield of bunches per vine, structural indicators of berries and sugar content in must. The analysis of the obtained results related with the analyzed grape varieties in the agro-ecological conditions of Northern Bosnia showed that those varieties can successfully be cultivated in similar or identical agro-ecological conditions

Some new models for multiprocessor interconnection networks

A multiprocessor system can be modeled by a graph G. The vertices of G correspond to processors while edges represent links between processors. To find suitable models for multiprocessor interconnection networks (briefly MINs), one can apply tools and techniques of spectral graph theory. In this paper, we extend some of the existing results and present several graphs which could serve as models for e cient MINs based on the small values of the previously introduced graph tightness. These examples of possible MINs arise as a result of some well-known and widely used graph operations. We also examine the suitability of strongly regular graphs (briefly SRGs) to model MINs, and prove the uniqueness of some of them

EFFECT OF CLIMATIC PARAMETERS ON UVOLOGICAL CHARACTERISTICS OF VARIETY ’BLATINA’

The winegrowing hills of Mostar as part of the Herzegovinian winegrowing region have always been considered suitable for grapevine cultivation, mostly as a result of favorable soil and climatic conditions. Herzegovina is home to a range of ancient grapevine varieties assumed to be indigenous to Bosnia and Herzegovina, with only few of them being commercial. 'Blatina' is the most important indigenous variety in Bosnia and Herzegovina intended for red wine production. It develops functionally female flowers, and the success of its fertilization is largely dependent on climatic conditions. This paper provides the results of an analysis of major bunch and berry characteristics conducted over a three-year period. Research findings indicate a significant effect of environmental conditions on some uvological traits of the bunch and berry

C - reactive protein and chitinase 3-like protein 1 as biomarkers of spatial redistribution of retinal blood vessels on digital retinal photography in patients with diabetic retinopathy

The aim of the study was to investegate the correlation between the levels of CRP and YKL-40 in blood samples with morphometric parameters of retinal blood vessels in patients with diabetic retinopathy. Blood laboratory examination of 90 patients included the measurement of glycemia, HbA1C, total cholesterol, LDL-C, HDL-C, triglycerides and CRP. Levels of YKL-40 were detected and measured in serum by ELISA (Micro VueYKL-40 EIA Kit, Quidel Corporation, San Diego, USA). Morphmetric analysis was performed with ImageJ software (http://rsbweb.nih.gov/ij/) for digital retinal photography. We measured the number, diameter of retinal blood vessels in five different parts concentric to the optic disc. Differences between the morphometric parameters and the blood test analysis results were evaluated using the Student’s t – test. One Way ANOVA was used to establish the significance of differences. CRP and YKL-40 levels were moderately higher in the group of patients with severe diabetic retinopathy. Levels of YKL-40 correlated positively with diameter and negatively with number of retinal blood vessels. The average number of the blood vessels per retinal zone was significantly higher in the group of patients with mild non-proliferative diabetic retinopathy than in the group with severe form in the optic disc and all five retinal zones. The average outer diameter of the evaluated retinal zones and optic disc vessels was significantly higher in the group with severe compared to the group with mild diabetic retinopathy. Morphological analysis of the retinal vessels on digital fundus photography and correlation with YKL-40 may be valuable for the follow-up of diabetic retinopathy
