Productivity of the maternal forms of sunflower hybrids depending on plant populations

Abstract: Ключевые слова: подсолнечник, материнская форма гибрида, густота стояния растений, продуктивность, структура урожая. В условиях 2017-2018 гг. на чернозёме выщелоченном Краснодарского края на примере константных самоопылённых линий -материнских форм гибридов подсолнечника ВК 101, ВК 678, ВК 905, ВА 760 и ЭД 765 селекции ФГБНУ ФНЦ ВНИИМК, изучали закономерности формирования урожая, его качество и структуру при выращивании их с густотой стояния растений 40, 50, 60 и 70 тыс. шт./га, со средней площадью питания одн… Show more

“…The sunflower root system in such sowings does not use water and nutrients fully enough, the plants use solar energy incompletely, and with an increase in the number of plants in a row, the competition for growth factors increases, which can manifest itself from the initial phases of development and hinder the realization of the productivity potential. As a result, researchers often fail to raise the sunflower yield by increasing the plant density (Ludanova et al, 2015;Vladimirov and Chugunov, 2018;Kurbanov et al, 2018;Lukomets and Tishkov, 2019;Tishkov and Shkarupa, 2020). In addition, this method of sowing does not consider the biological characteristics of individual genotypes, in particular, the height, number and size of leaves, the shape of the leaf blade and the general habitus of plants.…”

“…On the other hand, excessive consumption of animal fats is the main reason for the development of cardiovascular diseases (heart attack and stroke), which significantly reduce the life expectancy of the population of the Russian Federation. Therefore, due to changes in the diet of people over the past 10 years, the gross harvest of oilseeds in our country has a steady growth trend, which is also characteristic of the Republic of Tatarstan [4][5][6].…”

“…Было установлено, что растения декоративного подсолнечника реагирует на загущение посевов изменением габитуса, при этом снижается высота растения, сокращается площадь листьев и уменьшается диаметр куста, но это не приводит к дефектам морфотипа [2]. Выявлена отрицательная зависимость между диаметром соцветия подсолнечника и густотой стояния растений [3].…”
