Balancing forage production, seed yield, and pest management in the perennial sunflower silphium integrifolium (Asteraceae)
(Multidisciplinary Digital Publishing Institute, 2020-10)
The perennial sunflower Silphium integrifolium Michx. (Asteraceae), also known as silflower, is a prospective dual-purpose forage plus grain crop. Pre-flowering biomass harvest for animal feed and the subsequent delay in ...
Effect of Puccinia silphii on yield components and leaf physiology in Silphium integrifolium: Lessons for the domestication of a perennial oilseed crop
(MDPI AG, 2018-03)
New crops with greater capacity for delivering ecosystem services are needed to increase agricultural sustainability. However, even in these crops, seed yield is usually the main criteria for grain domestication. This focus ...
Progress and bottlenecks in the early domestication of the perennial oilseed Silphium integrifolium, a sunflower substitute
(MDPI, 2018-02)
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version of oilseed sunflower, its close relative. Grain crops with deep perennial root systems will provide farmers with new ...
From leaf traits to agroecosystem functioning: effects of changing resource use strategy during silphium domestication on litter quality and decomposition rate
(Springer, 2022-02)
Aims: We asked if structural and chemical changes in leaf traits, brought about by early domestication in perennial Silphium integrifolium Michx. (Asteraceae), have influenced litter quantity and quality, and decomposition ...
Accelerating silphium domestication: An opportunity to develop new crop ideotypes and breeding strategies informed by multiple disciplines
(Crop Science Society of America, 2017-06)
Silphium perfoliatum L. (cup plant, silphie) and S. integrifolium Michx. (rosinweed, silflower) are in the same subfamily and tribe as sunflower (Helianthus annuus L.). Silphium perfoliatum has been grown in many countries ...
