This study investigated the influence of plant density on several agronomic traits of four sunflower (Helianthus annuus L.) cultivars grown at Indian Head and Saskatoon, Saskatchewan in the semiarid prairies. At populations of 40 000–85 000 plants∙ha−1, plant density had no significant effect on seed yield. The increase in percentage oil content with increase in plant density (44.3–45.6%) was small but significant. As plant density was increased, days to flower, height and test weight increased while days to maturity, head diameter and average seed weight decreased. Cultivars × density interactions were generally not significant. Environment (five location-years) had a significant effect on all variables, and environments × cultivar interactions were significant for most of these. Results of this experiment indicated that testing of sunflower lines at several locations in the growing area would be necessary for best assessment but one plant density, suitable to that area, could be used.Key words: Sunflower, plant density, seed, oil, seed size, Helianthus annuus L.

This article reviews past successes and future potential of the use of interspecific hybrids in the breeding of cultivated Helianthus annuus, with emphasis on the necessity for conservation of non-cultivated germplasm. The topics discussed include resistance to diseases and other pests; the development of male-sterile lines for hybrid seed production; introduction of genes for various agronomic traits, such as drought resistance and cold tolerance; and attempts to change the chemical composition of the harvested crop.

Согласно литературным данным, подсолнечное масло богато полезными веществами, однако, в зависимости от степени очистки масла, количество этих компонентов варьируется. В данном исследовании был изучен дистиллят жирных кислот подсолнечного масла. Согласно полученным данным, более 40% состава кислот приходится на линолевую кислоту с F-витаминной активностью. В большом количестве содержатся стерины, составляющие 44% неомыляемого остатка. Токоферолы составляют 9% неомыляемого остатка, 93% из них приходится на a-токоферол. Helianthus annuus L необходим для приготовления натурального мыла, сочетает в себе способ приготовления медицинского мыла с технологией производства. Экстракт из стебля растения. Это свежее натуральное мыло содержит много полезных микро-и макроэлементов, биологически активные соединения и макро - и микроэлементы растения Helianthus annuus L были определены атомно-эмиссионным методом. Основными из них были K (44,9 мг/г), (377,745 мг/г), Na (3,91 мг/г), (7,56 мг/г) и Mg (3,06 мг/г), (1,495 мг/г). Эти элементы полезны для нашего организма и обладают целебными свойствами. Кроме того, в составе растения H. Annuus L. были определены биологически активные вещества, такие как флавоноиды, алкалоиды, органические кислоты, кумарины и витамины. Эти выявленные данные позволяют получать мыло с высоким качеством, а также целебными свойствами. Helianthus annuus L salt, which is necessary for the preparation of natural soap, combines the method of preparation of medical soap production technology. The extract from the stem of the plant. This fresh natural soap contains many useful micro and macronutrients, biologically active compounds and macro - and microelements of the plant Helianthus annuus L were determined by atomicemission method. Main of them were K (44.9 mg/g), (377.745 mg/g), Na (3.91 mg/g), (7.56 mg/g) and Mg (3.06 mg/g), (1.495 mg/g). These elements are useful for our body and have healing properties. In addition, biologically active substances such as fiavonoids, alkaloids, organic acids, coumarins, and vitamins were found in the composition of the plant H. annuus L. These identied data allow us to obtain soap with a high composition and quality and healing properties
