Genetic resistance to broomrape (Orobanche cumana Wallr.) in sunflower is mainly monogenic and dominant. Massive use of vertical resistance has led to the progressive extension of increasingly virulent races of the parasite. Additional introduction of horizontal resistance genes is crucial to develop more durable resistance. The objective of this research(More)
Sunflower (Helianthus annuus L.) seed oil with high palmitic acid content has enhanced thermo-oxidative stability, which makes it well suited to high-temperature uses. CAS-5 is a sunflower mutant line that accumulates over 25 % palmitic acid in its seed oil, compared to 5–8 % in conventional cultivars. The objective of this study was to investigate the(More)
The objective of this study was to evaluate the dynamics of tocopherols in cotyledons and radicles from sunflower seeds with high and low total tocopherol content, mainly in the α-tocopherol form, and from seeds with increased proportions of β-, γ-, and δ-tocopherol, both under dark and light conditions. Tocopherol content was measured every 24 h from 1 to(More)
Sunflower (Helianthus annuus L.) seeds have a tocopherol profile dominated by alpha-tocopherol. The objective of this research was to study the dynamics of tocopherol accumulation in sunflower lines with altered total tocopherol content or tocopherol profile. Developing seeds were sampled at regular intervals in two lines with reduced and increased total(More)
