Abstract:
Ornamental sunflower is used for cutting and sale in flower shops, for landscaping of cities and towns, and very intensively by amateur gardeners. On the Rus-sian market there were mainly sunflower seeds and plants (in flower shops) produced in Holland or Poland. In the State Register there were 21 domestic varieties of ornamental sunflower, which is obviously not enough for our country. Phenotypic uniformity of 27 ornamental samples from the VIR collection of 62 samples was confirmed as a result of a three-year study. New lines, which do not split by the studied traits during three years, wer

Abstract:
One of the many functions of sunflower (Helianthus annuus L.) is related to the use of its inflorescences in the flower market, which has guaranteed space for this species in floriculture in recent years. Sunflower has been highlighted as an ornamental plant for cutting. Studies have been performed aimed at reducing the size of this species, in order to improve its commercial production, which facilitates the production in field and in protected environments. The use of color shading nets can lead to growth manipulation and to the development of this species. The objective of this study was to

Abstract:
Head rot was found in cultivated sunflower (Helianthus annuus) in eastern New Mexico in Tucumcari in 2007 and Clovis in 2007 and 2009 and in south-central New Mexico near Las Cruces in 2009. The disease was also observed in wild sunflower near Clovis in 2008. Disease incidence was 10 to 40% in cultivated sunflower and ~30% in wild sunflower. Heads were brown to dark brown with discoloration extending down the sepals and peduncles into the stems. The basal parts of the heads were shredded and had grayish, fluffy mycelial mats visible in the lumen, and kernels were mostly seedless. Three to five

Abstract:
Drought stress during the reproductive phase of sunflower can significantly reduce achene yield by affecting inflorescence size, nectar quality, and pollinator activity. This study aimed to analyze the morphological characteristics of the reproductive region, quantify nectar sugar components, and evaluate pollinator presence and pollination success in wild Helianthus species as an important genetic resource for breeding cultivated sunflowers under drought conditions. Morphological investigations were conducted during the flowering and achene development phases with a stereo microscope and cali

Abstract:
Sunflower to be used in ornamental floral arrangements need to be free from damage, and have longer shelf life. The aim of the present study was to evaluate the effect of acetylsalicylic acid (ASA) on the postharvest longevity of ornamental sunflower. Floral stems of the cultivar Vicent’s Choice from Sakata Seed were placed in flasks containing 350 mL of solution containing 0, 200, 400, 600, 800, or 1000 mg of ASA per liter of distilled water. Aspirin® (acetylsalicylic acid) tablets were used as the source of salicylic acid. Grades from 0 to 5 were assigned every day, according to a pre-establ

Abstract:
The hybrid of the ornamental sunflower Sirius was obtained as a result of crossing two parent lines LD10 (variety of the ornamental sunflower Zhemchuzhny) and LD20. The main ornamental features of the hybrid Sirius are the original inflorescence, the light-yellow color of the ray flowers, the purple color of the tubular flowers, and the compact habitus. The hybrid belongs to the middle maturing group. The originator of the ornamental sunflower hybrid Sirius is the V.S. Pustovoit All-Russian Research Institute of Oil Crops (VNIIMK).

Abstract:
The Asteraceae family, also known as the sunflower family or daisy family, is the largest family of flowering plants with over 30,000 species found worldwide. The most distinctive feature is the inflorescence, called a capitulum or head. Many Asteraceae members are good sources of essential vitamins A, B, C, E, and K, folate, potassium, and healthy fats. They are also rich in antioxidants and prebiotics. However, some members also contain oxalates and Sesquiterpene lactones which can cause allergic reactions in some individuals (Song et al., 2020).

Abstract:
The method is proposed and the possibility of instantaneous remote determination of sunflower seed moisture using millimeter – range microwave radiation is experimentally investigated. A laboratory experimental setup was created to measure the reflection coefficient of electromagnetic waves from sunflower inflorescences in the frequency range of 25.86-37.5 GHz. In order to create a mathematical model that takes into account the difference between the reflected signal from the side of the inflorescence with sunflower seeds and the reverse side, experimental studies were conducted on the value o
