Factors Affecting Seed Germination of Heliopsis Helianthoides L. Sweet
Zlesak, D. C. Seed Science and Technology 35:577-594. 2007.
Low and erratic seed germination of Heliopsis helianthoides (L.) Sweet have hindered breeding efforts. The objectives of this study were to characterize seed dormancy and to investigate factors (cold stratification, ethylene, gibberellic acid, priming, and red light) as potential germination enhancers. Physiological, but not physical nor morphological seed dormancy was found.
