“…Bulbs are borne at the tip of vertical rhizomes and form contractile roots annually that pull bulbs deeper each year, and bulbils are formed in axillary buds of vertical rhizomes [134,135]. Bulbs and bulbils can be buried in the soil at a depth of 2-50 cm or even deeper [22]. Plants grow up to 40 cm tall, and their aerial parts are bright green in color; leaves are trifoliate, arise from an enlarged basal petiole apex, and are arranged in a loose basal rosette [136].…”

“…Bermuda buttercup bulbs sprout around mid-October before the first autumn rains, when soil temperatures are low enough to overcome bulb dormancy [141]. This usually coincides with the formation of contractile roots [22]. Flowering begins in early February and lasts until April.…”

“…At the end of flowering, in late spring, the aboveground part of the bulb disappears to reappear in autumn [132]. Paspatis [22] found that each plant produces 1-40 bulbs during a single growing season. Verdaguer et al [142] recorded a total production of more than 35 bulbs per plant, of which more than 20 were hypogeous, larger bulbs, and the rest were epigeous, smaller bulbs.…”

“…The spread of the bulbs can be localized due to the action of the contractile roots, which pull the bulbs away from the mother plant at distance of 40 cm; in just a few years, the soil is completely covered with a dense carpet of Bermuda buttercup [22]. In three years, plant density will exceed 100 plants m −2 [141].…”

“…Vegetative propagation allows for the rapid establishment of dense, monospecific, clonal populations in invaded habitats, which makes eradication a very challenging goal because it requires sufficient control of the belowground vegetative organs that give rise to new clonal plants. If only the aboveground vegetative parts are removed, plants regrow from their belowground vegetative organs [20][21][22][23][24]. In addition, seed production and dispersal facilitate effective colonization of new areas for species that can reproduce both by seed and vegetatively [15,21,25].…”

Invasive Alien Plant Species—Raising Awareness of a Threat to Biodiversity and Ecological Connectivity (EC) in the Adriatic-Ionian Region

Improving ecological connectivity (EC) within landscapes by establishing corridors and ecological networks has been proposed to counteract the negative effects of habitat fragmentation and climate change on biodiversity. To be functional, ecological networks should be kept free of opportunistic invasive species that can disrupt EC between protected areas and cause biodiversity loss. The present study focused on perennial herbaceous species whose occurrence in the Adriatic-Ionian region has increased in the last two decades, namely common milkweed (Asclepias syriaca), Jerusalem artichoke (Helianthus tuberosus), Japanese knotweed (Reynoutria japonica), Bohemian knotweed (Reynoutria × bohemica), giant hogweed (Heracleum mantegazzianum), giant goldenrod (Solidago gigantea), Canadian goldenrod (Solidago canadensis), and Bermuda buttercup (Oxalis pes-caprae). All species have a high potential to spread in grasslands, abandoned agricultural fields, forest edges, and riparian areas and pose a significant threat to native plant communities and biodiversity. Restoring heavily infested sites is a major challenge because these perennial invaders are very persistent and tend to alter the soil environment in invaded habitats and prevent the recolonization of native plant communities. Therefore, early action should be taken to prevent the spread of these environmental weeds in ecological networks and protected areas with high conservation value.

The competitive effect of Oxalis lali/olia H.B.K. (red garden sorrel) in maize has been investigated in the past four seasons at Cedara. The site chosen had a heavy o. lali/olia infestation. In each of the four seasons initial weed control was achieved on all plots using a mixture of atrazine, terbuthylazine and metolachlor. This treatment controlled a wide spectrum of weeds except o. lali/olia which became the dominant species present. On ten plots this weed was allowed to compete with maize throughout the season. This was compared with another ten maize plots where most of the o. lali/olia was selectively controlled. Maize grain yields, plant lodging counts and the incidence of Diflodia and Fusarium cob rots were not significantly altered by up to 329 well-developed o. lali/olia plants m-compared with up to 55 insignificant plants m-2 in the control plots. Die kompeterende effek van Oxalis lali/olia H.B.K. (rooituinsuring) is die afgelope vier seisone op mielies te Cedara ondersoek. Die perseel wat vir die proef gebruik is, is swaar met o. lali/olia besmet. In al vier seisoene is onkruide aanvanklik met 'n mengsel van atrasien, terbutielasien en metolachlor beheer. Hierdie behandeling het 'n wye spektrum van onkruide behalwe O./ali/olia, wat die dominante onkruid geword het, beheer. Hierdie onkruid is toegelaat om vir die he Ie seisoen Op tien persele met mielies mee te ding. Hierdie persele is met nog tien persele, waarop meeste van die o. lali/olia selektief beheer is, vergelyk. Mieliegraanopbrengs, die aantal staande en omgevalde plante en die voorkoms van Diplodia of Fusarium kopvrot is nie betekenisvol deur tot 329 sterk ontwikkelde o. lali/olia plante m-2 , in vergelyking met 55 swak ontwikkelde plante m-2 van die kontrole persele, be·invloed nie.
