In the interest of diversifying global food system, improving human nutrition, and making agriculture more sustainable, there have been many proposals to domesticate wild plants or complete domestication semidomesticated orphan crops. However, very few new crops recently fully domesticated. Many traits limiting their production consumption that could be costly slow change. Others may fortuitous preadaptations make them easier develop feasible as high‐value, albeit low‐yielding, To increase...
Silphium perfoliatum L. (cup plant, silphie) and S. integrifolium Michx. (rosinweed, silflower) are in the same subfamily tribe as sunflower ( Helianthus annuus L.). has been grown many countries a forage or bioenergy crop with quality approaching that of alfalfa Medicago sativa L.) biomass yield close to maize Zea mays some environments. large seeds taste oil similar traditional oilseed sunflower. species all long‐lived, diploid perennials. Crops from this genus could improve stability,...
Specific leaf area (SLA) is a key trait to screen plants for ecological performance and productivity; however, the relationship between SLA photosynthesis not always up-scalable growth when comparing multiple species with different life cycles. We explored anatomy in annual perennial of Physaria, related it water loss. The Physaria gracilis had higher SLA, thinner leaves, lower investment protective tissues, than P. mendocina. angustifolia (annual), pinetorum (perennial) showed intermediate...
Silflower (Silphium integrifolium Michx.) is in the early stages of domestication as a perennial version oilseed sunflower, its close relative. Grain crops with deep root systems will provide farmers new alternatives for managing soil moisture and limiting or remediating erosion, fertilizer leaching, loss biota. Several cycles selection increased seed production potential following initial germplasm evaluation 2002 have provided opportunities to document botany ecology this relatively...
• Background and Aims The use of perennial crops could contribute to increase agricultural sustainability. However, almost all the major grain are herbaceous annuals opportunities replace them with more long-lived perennials have been poorly explored. This follows presumption that life cycle is associated a lower potential yield, due reduced allocation biomass grains. hypothesis was tested perpetuation organs in L. mendocina would not be directly related seeds.
Abstract: While most lupin species possess quinolizidine alkaloids, sweet (low alkaloid) varieties are more palatable but at the same time susceptible to herbivory. Nevertheless, as they not totally devoid of it may be possible that their alkaloid levels increase after damage. The aim this study was compare inductive responses herbivory in and bitter Lupinus albus (L.) angustifolius (L.), assess if these were effective stop subsequent Two experiments carried out; first, Anticarsia gemmatalis...
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 grain domestication. This focus on can cause unintended structural and functional changes. Leaves of selected plants tend be more vulnerable infection, which reduce performance, assimilates, ultimately yield. Our objectives were determine impact rust (caused by Puccinia silphii) leaf function Silphium...
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 plant growth anthesis has potential to benefit seed yield and/or offset loss from native pests, such North American Eucosma giganteana (Lepidopera: Tortricidae). aim of this study was develop cropping technology silflower (A) balance production (B) minimize loss. Silflower...
