High interspecific competitiveness of the invasive plant Xanthium italicum Moretti severely reduces the yield and quality of Carthamus tinctorius L.

Abstract: Safflower is an annual herb of Compositae, which has great economic value. To explore the impact of invasive weed Xanthium italicum Moretti on the economic crop safflower, field experiments were conducted, the growth-related characters and the relative intensity of competition between the two species was explored. The results showed that under monoculture conditions, the stem height, crown width, stem diameter and the biomass of X. italicum root, stem and leaves were 1.14, 1.96, 1.82, 4.42, 4.21 and 3.99 times… Show more

“…In every 1 m 2 of farmland, when the number of alien invasive Xanthium strumarium L. reaches 1–2 plants, the yield of sunflower decreases by 30–40% and the yield of maize decreases by 80% [ 7 ]. When X. strumarium coexists with Carthamus tinctorius L., the biomass and seed yield of the latter decrease by more than 90% and 40%, respectively [ 8 ]. These exotic herbaceous plants in the aforementioned studies often have developed roots, large crowns, and rapid growth abilities and can compete with farmland crops for limited resources in a short period, realizing significant advantages [ 8 ].…”

These exotic herbaceous plants in the aforementioned studies often have developed roots, large crowns, and rapid growth abilities and can compete with farmland crops for limited resources in a short period, realizing significant advantages [ 8 ]. Notably, most of the literature on the growth and development characteristics and potential hazards of invasive plants has focused on herbaceous plants that are not invasive vines.…”
