Nicotiana(/ˌnɪkʃiˈnə,nɪˌk-,-kɒti-,-ˈɑːnə,-ˈænə/[2][3][4]) is agenusofherbaceous plantsandshrubsin thefamilySolanaceae,that isindigenousto the Americas, Australia, Southwestern Africa and the South Pacific. VariousNicotianaspecies,commonly referred to astobacco plants,are cultivated as ornamental garden plants.N. tabacumis grown worldwide for the cultivation oftobacco leavesused for manufacturing and producingtobacco products,includingcigars,cigarillos,cigarettes,chewing tobacco,dipping tobacco,snuff,andsnus.

Etymology

[edit]

The genusNicotiana(from which the wordnicotineis derived) was named in honor ofJean Nicot,French ambassador to Portugal, who in 1559 sent samples as a medicine to the court ofCatherine de' Medici.[11]

Ecology

Despite containing enoughnicotineand/or other compounds such asgermacreneandanabasineand otherpiperidine alkaloids(varying between species) todetermostherbivores,[12]a number of such animals haveevolvedthe ability to feed onNicotianaspecies without being harmed. Nonetheless, tobacco is unpalatable to many species and therefore some tobacco plants (chiefly tree tobacco (N. glauca)) have become established asinvasive speciesin some places.[13]

In the 19th century, young tobacco plantings came under increasing attack fromflea beetles(the potato flea beetle (Epitrix cucumeris) and/orEpitrix pubescens), causing the destruction of half the United States tobacco crop in 1876. In the years afterward, many experiments were attempted and discussed to control the potato flea beetle. By 1880, it was discovered that covering young plants with a frame covered with thin fabric (instead of with branches, as had previously been used for frost control) would effectively protect the plants from the beetle. This practice spread until it became ubiquitous in the 1890s.[citation needed]

Tobacco, alongside itsrelated products,can be infested byparasitessuch as the tobacco beetle (Lasioderma serricorne) and the tobacco moth (Ephestia elutella), which are the most widespread and damagingpestsin thetobacco industry.[14]Infestation can range from the tobacco cultivated in the fields to theleavesused for manufacturingcigars,cigarillos,cigarettes,chewing tobacco,dipping tobacco,etc.[14]Both thegrubsofLasioderma serricorneand thecaterpillarsofEphestia elutellaare considered major pests.[14]

Cultivation

[edit]

Several species ofNicotiana,such asN. sylvestris,[17]N. alata'Lime Green'[18][19]andN. langsdorffiiare grown asornamental plants,often under the name of flowering tobacco.[5][20]They are popularvespertines(evening bloomers); their sweet-smelling flowers opening in the evening to be visited byhawkmothsand otherpollinators.In temperate climates, they behave asannuals(hardiness9a-11).[21] Thehybridcultivar'Lime Green'[19]has gained theRoyal Horticultural Society'sAward of Garden Merit.[22]

Garden varieties are derived fromN. alata(e.g., the 'Niki' and 'Saratoga' series) and more recently fromNicotiana×sanderae(e.g., the 'Perfume' and 'Domino' series).[20]

The tobacco budworm (Chloridea virescens) has proved to be a massive "pest" of many species in the genus, and has resisted many attempts at management.[23]
