"The explanation is that there are two parts of the plant which can be used; the pale seeds and the red florets. The main shoot reaches heights of 30-150 cm (12-59 in). Rain and high humidity after maturity may cause the seeds to sprout on the head. Safflower oil is the richest in polyunsaturated fatty acid (linoleic acid, 77%). (2008). [8] Therefore, many varieties are not suitable in irrigated agriculture especially on soils with danger of waterlogging. [13] Cultivation on fields with heavy infestation of perennial weeds is not recommended. [13] Where lower seeding rates promote branching, a longer flowering period and later maturity and higher rates promote thicker stands with a higher disease incidence. Featured Industry Food and Beverages format neat functional group carboxylic acid ... Use the chromatographic fingerprint of our reference material to check for the presence of safflower oil in your sample. It is commercially cultivated for vegetable oil extracted from the seeds and was used by the early Spanish colonies along the Rio Grande as a substitute for saffron. Do not rotate with cotton, peanuts and other susceptible crops. [8] Therefore cultivation on shallow soils and especially on soils with danger of waterlogging is not suitable. Crossings with Carthamus palaestinus, Carthamus oxyacanthus and Carthamus persicus can produce fertile offspring. Red-brown necrotic spots on leafs. [8] In early stages, safflower tolerates humidity but after bud stage the danger of a Botrytis blight infestation increases[8], Safflower is drought tolerant.

The latter is used in painting in the place of linseed oil, particularly with white paints, as it does not have the yellow tint which linseed oil possesses. Drying can be done similar to sunflower. [13] Close rotation with crops susceptible to Sclerotinia sclerotiorum should be avoided (e.g. Usually, row spacing between 15 and 25 cm are chosen using similar drill settings as recommended for barley.[13]. Germination of safflower is epigeal. Depending on variety, crop management and growing conditions, each plant can develop 3–50 or more flower heads of 1.25–4 cm diameter.
