Mayelana nalolu hlelo lokusebenza

Izikhulu eMnyangweni United States of Agriculture (USDA) usutholile ukuthi ezithile zinhlobo zimila US basengozini yokuba koda kufanele bangene kuleli zwe. Njengengxenye yemizamo ukuvimbela ukwethulwa ukhula koda noma engase koda, lo USDA igcina uhlu olusemthethweni "ukhula federal kumoya" (FNW) (7 CFR 360,200 kanye 361.6). Abaningi taxa hlu njengamanje ukhula sína kwenye indawo emhlabeni, futhi cishe izingxenye ezimbili kwezintathu the taxa njengamanje ezitholakala US Iningi labantu taxa FNW kuthiwa angiosperms, kodwa bambalwa Izinhlobo futhi enye alga green. QAPHELA ukuthi Izinhlobo futhi alga abafakiwe kulolu hlelo lokusebenza.

Izithelo kanye imbewu simila disseminules obhekene kakhulu ukusabalala ukhula ezindaweni ezintsha. Federal kumoya Weed Disseminules of the US Keys yasungulwa ukuze sikwazi ukuhlonza olunembile FNW angiosperm disseminules. Amakhi ezintathu (zotshani = Poaceae; Legumes = Fabaceae; futhi Umphumela Angiosperm Plant Imindeni) badalwa ukuba esetshenziswa izikhulu US emachwebeni obhekene ukuhlonza plant izinambuzane. Kungase kube indlela ewusizo for inzalo ochwepheshe kanye ubani omunye nge isithakazelo, noma okudingeka ukwazi, kumoya ukhula disseminules.

Imindeni Abangamaphesenti-njengamanje amelwe ohlwini FNW njengoba of 2013. Iningi the taxa ezingaba ngabanye, kodwa ezimbili ezingaba izakhiwo, Rubus fruticosus L. agg. futhi Salvinia auriculata eziyinkimbinkimbi (hhayi kufakwe isihluthulelo lokusebenza kusukela an Ferm yasemanzini), futhi enye kuyinto taxon infraspecific ( Setaria pumila (Poir) Roem & amp;.. Schult. ssp. pallidefusca (Schumach) BK Simon). Qaphela ukuthi amashidi qiniso ngoba kwezinhlobo FNW of izizukulwane eziyisithupha Aeginetia , Alectra , Cuscuta , Moraea , Orobanche , Striga abaye baphathwa ndawonye zabo siqu "bohlobo-level" Empeleni amashidi.

Amakhi omkhaya amathathu interactive zihlanganisa lezo kuphela FNW taxa ukuthi lokuveza inzalo futhi izithelo disseminules (ie, angiosperms). Taxa Eight abafakiwe amakhi interactive noma ngoba bengafuni ukuzala angiosperm nasele awoke noma kuzala inzalo kuyaqabukela kuphela. Elinye iqembu izithelo entula futhi imbewu kuyizinto Izinhlobo, lapho nokuzala via ezinhlamvu kanye esebenzisa vegetative. Ukuveza nge disseminules vegetative iyindlela eyinhloko zisakaza for abanye non-Izinhlobo (angiosperms emithathu alga) kanye. The taxa eziyisishiyagalombili hhayi amakhi kukhona Izinhlobo terrestial Lygodium flexuosum (L.) SW. futhi Lygodium microphyllum (Cav.) R. Br., i Izinhlobo emanzini Azolla pinnata R.Br. kanye Salvinia auriculata eziyinkimbinkimbi, lezi angiosperms emanzini Hydrilla verticillata (LF) Royle futhi Lagarosiphon ezinkulu (Ridley) Moss, lo oyinyumba angiosperm hybrid Opuntia aurantiaca Lindl., futhi alga Caulerpa taxifolia (Vahl) Agardh.

Zonke izithombe ezithwetshuliwe zakhiqizwa abalobi ngaphandle lapho lavuma imibhalotihumusho image. Bheka FNW ithuluzi Imihlahlandlela efanele ukusetshenziswa futhi ukulandisa kwezithombe. Iningi imifanekiso original wakudonsela Lesley Randall. Okusele abadonsekela by Ingrid Hogle futhi Julia Scher. Imidwebo by Lynda E. Chandler kukhona kusukela Gunn futhi Ritchie (1988). Imidwebo by Regina O. Hughes kukhona kusukela uTerrell Peterson (1993) kanye Reed (1977).
