Species from Cucurbitaceae family are not widely present in Serbia, although because of their morphological and decorative features deserve more attention. The aim this paper was to study the variability usage ten species Cucurbiataceae family. Based on genetic variability, were grouped into 8 clusters. Fruit characteristics most investigated showed great similarity greatest differences attained for flower fruit characteristics. longest Trichosanthes cucumerina (46.2 cm), while shortest...

Summary This study tested the hypothesis that a third dimension of urban gardening, in form green terraces and balconies, is immense importance to public well-being, mitigating climate changes contributing more pleasant life highly urbanized zones. By means concise questionnaire, total 82 respondents different age groups (20-70 years age) were surveyed about their opinion on terraces, roofs, i.e. plants flowers they incorporate. The fieldwork survey responses facilitated design ten spaces...

Pansy (Viola tricolor var. hortensis DC.) is a biennial large-flowered hybrid plant cultivated as popular ornamental in urban green areas. The plants prefers sun and well-drained soil, but also tolerate low temperatures. optimal time for transplanting pansy seedlings outdoors beds autumn, although early autumn frosts can affect the insufficient nutrient uptake, which be limiting factor seedling survival. To avoid these effects, treated with different growth stimulants such biostimulant...

Adaptability and allometric relations of Acer pseudoplatanus A. "Atropurpureum" at different urban sites are investigated in this work via the diameter breast height (dbh), tree height, crown width measurements, which served as ordinary least-squares regression model inputs. Differences between "Atropurpureum," well intraurban variations trees growing site categories (park street) location same category with morphology characteristics, were noted. The strongest noted for width/tree...

Sunflower (Helianthus annuus L.) is grown commercially and as an ornamental plant. Floral colour inflorescence type are important traits in the breeding of sunflower. Sunflowers consist ray florets, which arranged around perimeter with disc florets centre. The can vary from various shades red to lemon-yellow. inheritance floret was studied through diallel crossing inbred lines red, yellow, or lemon-yellow coloured florets. In F1 generations, partially dominant over yellow forming a...

The aim of this research was to determine the optimum planting density for production high-quality cut flowers with desirable characteristics. 25 single-stem ornamental sunflower genotypes were planted at different densities and evaluated flowering time, flower diameter, stem circumference length over a two-year cycle. Three spacing patterns used: × cm, 30 70 which led 160 000, 90 60 000 plants/ha, respectively. plant had most important effect on circumference, (total variation 52, 60, 58%,...

This study presents research on the chemical composition of 15 horse chestnut seed genotypes (Aesculus hippocastanum L.) conducted three different sites. The seeds were picked from selected trees in Backa Palanka, Novi Sad and Sremski Karlovci at end September 2010. statistical parameters point out variables examined features seed. On basis moisture, starch, fat protein contents seeds, genotypes, reproductive material which would be used for intensive production high grade seedlings greening...

The research describes the field comparison of 81 decorative sunflower genotypes. In order to assess genetic diversity genotypes studies were conducted in conditions during 2010-2015 at Institute Field and Crops, Novi Sad, Serbia. species Helianthus annuus L. has enabled breeding work direction decorating plant landscaping. Depending on qualitative quantitative characteristics, production sunflowers can be divided into three directions. first line is for cut flowers, second one garden third...

Summary Ecosystem services have been the focus of recent research on ecology, biodiversity and human health. As most this has placed emphasis natural ecosystems, there is a lack data effect indoor urban ecosystems both health quality life. One common issues associated with spaces air. Considering that humans spend their time indoors, accompanied by fresh air due to industry growth environmental degradation, an obvious need for non-invasive non-obtrusive purification system. This paper...

As an esthetic trait, ray floret color has a high importance in the development of new sunflower genotypes and their market value. Standard methodology for evaluation florets is based on International Union Protection New Varieties Plants (UPOV) guidelines sunflower. The major deficiency this necessity expertise from evaluators its subjectivity. To test hypothesis that humans cannot distinguish colors equally, six commercial were evaluated by 100 agriculture experts, using UPOV guidelines....

Bottle gourd [Lagenaria siceraria (Molina) Standl.] is one of the most interesting species in plant kingdom, due to diversity fruit shapes, sizes and ways use. Warty genotypes are rare compared non warty genotypes. Considering unusual external appearance fruits, we focused our research on investigation its inheritance patterns. By crossing different bottle phenotypes, studied mode identified verified genes responsible for skin color phenotype segregation. Two parental lines, LAG 70 (with...
