Diffusible gibberellins and phototropism in Helianthus annuus [PDF]
Planta, 1972 Endogenous gibberellins were obtained in agar from the lower cut surface of upright sunflower shoot-tips. Exposure to unilateral light of the tips standing on agar, with the lower cut ends bisected by a vertical glass barrier at right angles to incident light, resulted in approximately 8 times the quantity of gibberellins moving into the agar below the

A microsatellite marker in Helianthus annuus L.
Plant Molecular Biology, 1994The importance of genetic polymorphism detected by 'microsatellites' is now well established in mammalian genomes. Sequences with a CA repeat, specific to sunflower, Helianthus annuus L., were found by screening a genomic library in M13. After amplification, some polymorphism was detected on these sequences within a sample of cultivars and populations.

The Optimal Growth of Helianthus Annuus
Journal of Theoretical Biology, 1993Abstract The history of optimality theory and its application to plant growth is reviewed. The theory is developed for Helianthus Annuus and compared to the actual growth data for this plant, assuming that the objective of the plant is to maximize the amount of its reproductive portion within one growing season.

Micropropagation of Sunflower (Helianthus annuus L.)
1992The common sunflower (Helianthus annuus L.) is a member of the Compositae (Asteraceae) family. Its name (from the Greek helios, sun, and anthos, flower) is derived from the heliotropic movement of the sunflower’s head (nutation). Grown for its seed, this species is one of the most important suppliers of vegetable oil, and is now fairly widely ...

Suncokret Helianthus annuus L.
2004Kulturni suncokret Helianthus annuus L. u svjetskom uljnom kompleksu rangira se kao jedna od četiri najvažnije jednogodišnje kulture za proizvodnju kvalitetnog jestivog ulja. Suncokret u R. Hrvatskoj relativno je nova kultura, u odnosu na glavne ratarske kulture, jer se sije u kontinuitetu zadnjih pedesetak godina.

Characterization of Helianthus annuus L. storage proteins
Journal of Agricultural and Food Chemistry, 1989A rapid method is described for isolating the globulin fraction (helianthinin) of sunflower seeds (Helianthus annum L.). The protein was characterized by chromatography and electrophoresis and compared with the globulin extracted from protein bodies.

Characteristics of action potentials in Helianthus annuus
Physiologia Plantarum, 1991The action potentials induced by nondamaging electrical stimuli in 16‐ to 22‐day‐old plants of Helianthus annuus were examined. Typical recordings are presented. Mean values of their amplitudes and conduction velocities in the stem, the strength‐duration relation, the ‘all‐or‐none’ law and the refractory periods have been determined.

Genomic alterations in the interspecific hybrid Helianthus annuus×Helianthus tuberosus
Theoretical and Applied Genetics, 1998The genome of a Helianthus annuus (2n=34) ×Helianthus tuberosus (2n=102) hybrid was studied at cytological, biochemical and molecular levels and compared to those of the parental species. Cytophotometric analyses showed that the hybrid has a 4C DNA content higher than expected and with a larger variability than in the parents.

DEVELOPMENT OF OIL IN THE SEED OF HELIANTHUS ANNUUS L.
Canadian Journal of Biochemistry and Physiology, 1961Sunflower seed (Helianthus annuus L.) was collected from growing plants at weekly intervals. Analyses of the seed, the oil, and the fatty acids were made, the latter by gas chromatography. Oil formation began about 10 days after flowering and continued at a steady rate for 7 weeks.
