“…Sunflower is an annual crop produced for its seed and is the fourth most important oilseed crop responsible for 10% of the world's edible plant-derived oil (Dantas et al, 2017). The leaves and stems are usually not harvested and left on the field as organic compost.…”

A survey of plant-based wastes identified sunflower (Helianthus annuus) bark extract (SBE), produced via twin-screw extrusion, as a potential biostimulant. The addition of SBE to Arabidopsis (Arabidopsis thaliana) seedlings cultured in vitro showed a dose-dependent response, with high concentrations causing severe growth inhibition. However, when priming seeds with SBE, a small but significant increase in leaf area was observed at a dose of 0.5 g of lyophilized powder per liter. This optimal concentration of SBE in the culturing medium alleviated the growth inhibition caused by 100 mM NaCl. The recovery in shoot growth was accompanied by a pronounced increase in photosynthetic pigment levels and a stabilization of osmotic homeostasis. SBE-primed leaf discs also showed a similar protective effect. SBE mitigated salt stress by reducing the production of reactive oxygen species (ROS) (e.g., hydrogen peroxide) by about 30% and developing more expanded true leaves. This reduction in ROS levels was due to the presence of antioxidative agents in SBE and by activating ROS-eliminating enzymes. Polyphenols, carbohydrates, proteins, and other bioactive compounds detected in SBE may have contributed to the cellular redox homeostasis in salt-stressed plants, thus promoting early leaf development by relieving shoot apical meristem arrest. Sunflower stalks from which SBE is prepared can therefore potentially be valorized as a source to produce biostimulants for improving salt stress tolerance in crops.

“…Sunflower seed contains ∼15 g protein, ∼58 g total lipid (fat), ∼3 g ash, and ∼24 g carbohydrate with 675 kcal total energy per 100 g (Prado et al., 2020). Sunflower cultivation is mainly carried out to obtain oil for human consumption and biofuel production (Dantas et al., 2017). Figure 1 shows a flowchart of sunflower seed processing for oil production that results in sunflower seed byproducts (whole and defatted sunflower meals) (Figure 2).…”

“…In terms of production, it is the third‐most oilseed produced in the world, the fourth‐most important culture in vegetable oil production and the third‐most important culture in oilseed meal production; among other protein sources (Dantas et al., 2017; Pilorgé, 2020). Sunflower is a globally important oilseed, food, and ornamental crop and the seed accounts for approximately 10% of the world's edible plant‐derived oil (Dantas et al., 2017; Del Gatto et al., 2015; Seiler et al., 2017). The USA, Ukraine, and Argentina are the main world producers of sunflower (Dantas et al., 2017).…”

The sunflower (Helianthus annus L.) is one of the main oil crops in the world grown for the production of edible and biodiesel oil. Byproducts of the extraction of sunflower oil constitute a raw material with potential for several applications in the food area due to its chemical composition, including the high content of proteins and phenolic compounds. Thoughtful of a consumer increasingly concerned with the environmental impact, we try to clarify in this review the potential of using sunflower seed byproducts and their fractions to enhance the production of potentially functional foods. The applications of sunflower seed byproduct include its transformation into flours/ingredients that are capable of improving the nutritional and functional value of foods. In addition, the protein isolates obtained from sunflower seed byproduct have good technological properties and improve the nutritional value of food products. These protein isolates can be used to obtain protein hydrolysates with technological and bioactive properties and as matrices for the development of edible, biodegradable, and active films for food. The sunflower seed byproduct is also a source of phenolic compounds with bioactive properties, mainly chlorogenic acid, which can be extracted by different methods and applied in the development of functional foods and active and bioactive food packaging. The use of sunflower seed byproduct and its fractions are promising ingredients for the development of healthier and less expensive foods as well as the alternative to decrease the environmental problems caused by the sunflower oil industry.

“…The sunflower (Helianthus annuus L.) is one of the most important oleaginous species worldwide, being cultivated in all continents (CASTRO;LEITE, 2018). Sunflower crops are mainly used to produce seed oil for human consumption and to produce biofuels (DANTAS et al, 2017). The average Brazilian yield of sunflower (average grain yield) is 1319.3 kg ha -1 , which is considered low when compared to other countries, such as the Ukraine with 2238.8 kg ha -1 (FAO, 2016).…”

Effects of Competition and Water Deficiency on Sunflower and Weed Growth

et al. 2019

In the agricultural environment, the occurrence of biotic and abiotic stresses, such as weed interference and soil water deficit is common. However, little is known about the effects of the interaction of these stresses on the growth of cultivated crops and weed species. Thus, the objective of this study was to evaluate the effects of competition and water deficiency on the growth of sunflowers and weeds. The experiment was performed in a randomized block design with four replications. The treatments were arranged in a 5 × 2 factorial design, with the first factor corresponding to the competition arrangements between the species (sunflower + Waltheria indica; sunflower + Amaranthus spinosus; and sunflower, W. indica, and A. spinosus in monoculture without competition) and the second factor corresponding to water regimes (irrigated and water deficit). The water deficit regime was established when the sunflower plants had six expanded leaves (V6 stage) and was maintained until the rate of CO2 assimilation of the plants reached values close to zero (6 days), after which irrigation was resumed and maintained until 40 days after emergence, when the plants were collected and evaluated. The growth components evaluated were plant height, leaf area, dry leaf mass, dry stem mass, dry root mass, and total dry mass. Competition between plants decreased sunflower, W. indica, and A. spinosus growth. W. indica and A. spinosus aggravated the negative effects of water deficiency on sunflower growth. The water deficit regime did not affect the growth of W. indica. A. spinosus was more competitive with the sunflower than was W. indica.
