چکیده
Asclepias syriaca L. (ASCSY, fam. Apocynaceae) is a weed originating from the northern parts of central, northeastern and southeastern America, as well vicinal areas Canada. The common milkweed was introduced to Europe at beginning 19th century honey, ornamental fiber/silk plant. Today, it occurs in many countries western Central (France, Austria, Czech Republic, Belgium, Germany, Lithuania, Slovakia, Hungary, Poland, Italy, Slovenia, Croatia, Serbia, Bosnia, Romania, Bulgaria Russia). first cases A. Serbia were noted 1920s. most on non-agricultural areas, where spreads surrounding cultivated areas. This perennial species can grow up 1.2 m has plenty underground adventitious buds which reproduces vegetatively. spherical umbels are axis upper leaves, flowers have pleasant smell purple deep purplish pink color. It diploid (2n = 22), self-pollinating plant, with hybridization between genus being very rare. One plant produce 1-6 fruits, every fruit containing 150-425 seeds. prefers fertile, well-drained soils, but also thrives dry soils. optimal development achieved moderately light warm, neutral slightly alkaline habitats, tolerating soil pH values 4-5. seeds germinate temperature 20-30ºC. Late frosts -1 -2ºC destroy young seedlings, while adult plants survive that temperature. allelopathic properties negative impact towards number plants, both crops (maize, soybean, sunflower Sorghum) weeds (Amaranthus retroflexus, Chenopodium album, Lepidium sativum Ambrosia artemisiifolia). affect seed germination crop leading significant yield reduction when its occurrence massive. control measures include: rotation, cultivation competitive crops, mechanical removal along roots, chemical recommended preventive method, using glyphosate triclopyr prevent entering fields.

Coexistence of three specialist aphids on common milkweed, Asclepias syriaca.
Coexistence of host-specific herbivores on plants is believed to be governed by interspecific interactions, but few empirical studies have systematically unraveled these dynamics. We investigated the role of several factors in promoting coexistence among the aphids Aphis nerii, Aphis asclepiadis, and Myzocallis asclepiadis that all specialize on common milkweed (Asclepias syriaca). Competitive ...

Natural selection on common milkweed (Asclepias syriaca) by a community of specialized insect herbivores
Hypothesis: Genetic variation in plant defence structures a community of herbivores and ultimately mediates co-evolution. Organisms: Common milkweed (Asclepias syriaca) and five natural insect herbivores (seed bug, leaf mining fly, monarch caterpillar and two beetles). Methods: Quantitative genetic field experiment over 2 years, genetic selection analyses, and measurement of five defensive trai...
متن کاملGrowth–defense tradeoffs for two major anti-herbivore traits of the common milkweed Asclepias syriaca
Costs of plant defense are a key assumption in evolutionary ecology, yet their detection has remained challenging. Here we introduce a novel method for quantifying plant growth using the common milkweed Asclepias syriaca and repeated non-destructive size measurements to experimentally test for costs of defensive traits. We estimated mechanistic components of plant growth (relative growth rate, ...
متن کاملIsolation and characterization of microsatellite loci in the common milkweed, Asclepias syriaca (Apocynaceae).
PREMISE OF THE STUDY Microsatellite primers were developed for the common milkweed, Asclepias syriaca L., to assist in genet identification and the analysis of spatial genetic structure. METHODS AND RESULTS Using an enrichment cloning protocol, eight microsatellite loci were isolated and characterized in a Michigan population of A. syriaca. The primers amplified di- and trinucleotide repeats ...
