Notes on Taxonomy and Nomenclature

Top of page

Solanum nigrum L. (Family Solanaceae; English name: Black night shade) is one of the largest and most variable species groups of the genus. Though this species group is often referred to as Solanum nigrum complex, the section is composed of a large number of morpho-genetically distinct taxa, which show their greatest diversity and concentration in the New World tropics, particularly in South America (Jagatheeswari et al., 2013). 

Description

Top of page

S. nigrum is a very variable ephemeral, annual or sometimes biennial herb, 0.2–1.0 m tall, reproducing only by seed. It has a strong white taproot, with many lateral roots being produced in moist and fertile surface soils.

Stems vary from prostrate to ascending or erect, and from herbaceous in ephemeral plants to rather woody or even shrubby in those that survive long enough to be biennial. Stems are round or angular, smooth or sparsely hairy, and green to purplish.

Leaves are alternate, ovate and are carried on short stalks, 2–8 cm long, and vary between plants from smooth-edged to shallowly lobed. They are opaque, matt and dark green both above and below, and either smooth or finely hairy.

The small, white, star-shaped flowers are carried in umbels on slender stalks developing directly from the stems between the leaves. Each cluster usually carries from 5–10 flowers, which open sequentially over several days. The flowers are 5-8 mm across, and have prominent yellow centres.

Fruits are globular, dark green, matt berries 5–13 mm across, matt black when ripe, which contain many flattened, finely pitted, yellow to dark brown woody seeds approximately 1.5 mm long.

Seedlings of S. nigrum agg. all exhibit epigeal germination. The hypocotyl is commonly slender, about 1 cm long, green or purplish and distinctly hairy. The spreading cotyledons are slender, about 5 mm long, and taper towards the tips. The epicotyl is slender, smooth to finely hairy, and carries small, ovate, juvenile leaves that gradually assume the adult shape and size.

Distribution

Top of page

Species are distributed from temperate to tropical regions, and from sea level to altitudes over 3500 metres. S. nigrum agg. appears to be distributed throughout the world, and one or more members of the complex probably occur in every nation from Finland in the northern hemisphere to New Zealand in the southern hemisphere. Solanum nigrum itself is a predominantly Eurasian species, which does not occur naturally in South America (Jagatheeswari et al., 2013).

Habitat

Top of page

Members of the S. nigrum complex are largely confined to disturbed situations such as cultivated land, roadsides, wasteland, uncompetitive pastures, and exposed river beds and banks. They occur in such places throughout the temperate zones and in subtropical and tropical countries from sea level to 3000 m. In cold and cooler temperate areas they usually grow as summer annuals, but in subtropical and tropical areas either during the moister seasons or throughout the year.

S. nigrum agg. thrive under disturbed moist warm fertile conditions with full or partial sunlight, becoming less competitive where soils are drier, cooler and less fertile or where there is heavy shade from taller crops. It is best adapted to fertile soils, especially those high in nitrogen and phosphorus.

Biology and Ecology

Top of page

Despite the almost global range of S. nigrum agg., little has been written on the biology of this group of weeds. It is likely that scientific literature may only apply to the genotype of the taxon under discussion, due to the considerable genetic variation of the compex, its wide climatic range and apparent phenotypic plasticity.

As many as 178,000 seeds may be produced per year. Seeds germinate best at alternating temperatures of 20-30°C, and there is little initial dormancy (99% of seeds germinate in the spring after collection and stratification). Seeds stored indoors at room temperature retained 27% germination after 2 years, but only 2% and 0% after 8 and 9 years, respectively (Andersen, 1968). In Israel, Givelberg et al. (1984) found a very similar situation, but showed that light improved germination and seed longevity in storage was 2-3 years.

As may be expected, S. nigrum agg. seeds from Europe germinate best in the spring (May–June), cease germination in the autumn (September–October), and remain dormant over the winter (November-March) (Roberts and Lockett, 1978). The same seasonality was observed in local genotypes in New Zealand by Popay et al. (1995). Roberts and Lockett (1978) showed that there was a strict requirement for diurnal temperature fluctuations in their genotype, a view supported by Kazinczi and Hunyadi (1990) who also showed differential germination between seeds from fruits of various colours.

Seeds of the S. nigrum complex appear to be presented for distribution by birds, and Barnea et al. (1990) showed that whereas germination of S. nigrum was unaffected by bird ingestion, that of S. luteum was significantly improved. Seeds in pig manure were killed by heating to 75°C for 3 minutes (Bloemhard et al., 1991).

Sattin et al. (1992) have shown that S. nigrum is a C3 plant.

Notes on Natural Enemies

Top of page No natural enemies have been recorded for S. nigrum, although it has been shown to be a host for many nematode and virus pests, and the thrip pest Frankliniella occidentalis (Lacasa et al., 1996).

Impact

Top of page

S. nigrum is a serious competitor with the seedling stages of many horticultural and agricultural crops for water, light and nutrients, especially with widely spaced and low-growing horticultural crops such as tomatoes (Burgert et al., 1973, McGiffen et al., 1992) and peppers (Torner et al., 1993), and in nurseries (Gilchrist, 1988).

Seeds of S. nigrum agg. can contaminate similarly-sized crop seeds, for example, those of phlox (Phlox spp.) (Koppenhol, 1986). The purplish juice of the fruits can stain beans during harvest (Burgert et al., 1973).

S. nigrum is an alternate host of the fungus Cercospora albo-marginalis, nematodes (species of Meloidogyne, Rotylenchus reniformis and an unnamed sugarbeet nematode) and of many viral diseases including cucumber mosaic cucumovirus, tobacco mosaic tobamovirus, tomato spotted wilt tospovirus, aster yellows, atropa belladonna mosaic rhabdovirus, beet curly top hybrigeminivirus, cucumber green mottle mosaic tobamovirus, alfalfa mosaic alfamovirus, mosaic, potato A potyvirus, potato leafroll luteovirus, potato T trichovirus, raspberry ringspot nepovirus, tobacco leaf curl bigeminivirus, tobacco ringspot nepovirus, tobacco streak ilarvirus, tobacco yellow dwarf monogeminivirus and potato X potexvirus (Holm et al., 1991).

S. nigrum agg. is a particularly serious weed in mechanically harvested peas, since the (poisonous) green berries which are also harvested are inseparable from the green peas.

The green fruits, and to a lesser extent, the plant itself are toxic to cattle, horses and pigs, as well as humans (Vogel and Gutzwiller, 1993).

S. nigrum has been shown to be highly allelopathic to a number of test plants in bioassays (Souto et al., 1990).

Uses

Top of page

Genotypes of the S. nigrum complex with large fruits are sometimes cultivated, the fruit being used in pies, and young shoots are also sometimes eaten as pot herbs (Edmonds and Chweya, 1997; Mabberley, 1997). The taxon is very variable, and edible cultivars could undoubtedly be selected and improved by standard plant breeding methods.

In most parts of the world, particularly in Europe and North America, these species are considered to be troublesome weeds of agriculture, but in many developing countries they constitute a minor food crop, with the shoots and berries not only being used as vegetables and fruits, but also for various medicinal and local uses (Jagatheeswari et al., 2013).

Similarities to Other Species/Conditions

Top of page

S. nigrum is one of a group of similar species (S. nigrum agg.), all of which occur as weeds in similar situations and which sometimes occur together. They are numerous in different parts of the world:

- S. americanum, which has translucent, paler green leaves, glossy immature and mature fruits and is a very widespread weed

- S. luteum, which has yellow berries and occurs in the Middle East

- S. retroflexum, a common weed that is very similar in appearance to S. nigrum, but has shallowly to deeply lobed leaves, paler below than above, and occurs widely as a weed

- S. sarrachoides, which occurs worldwide and can be distinguished by having the greenish fruit enclosed in an enlarged persistent calyx and fine hairs on the stems and leaves

- S. triflorum, another similar weed to S. nigrum, but the flowers are in groups of 1-3 and the mature fruits are marbled white and green (Symon, 1981).

Prevention and Control

Top of page

Cultural Control

Plants should be hand pulled or mechanically controlled before flowering, and for some crops grown in rows this has been shown to be quite effective (Dastghieb et al., 1995).

Chemical Control

S. nigrum is susceptible to a wide range of herbicides, including:

- acetochlor (preplanting; Lorenzi, 1986)
- aciflourfen (post-emergence; Lorenzi, 1986)
- ametryn (pre- and post-emergence; Lorenzi, 1986)
- atrazine (pre-emergence; Lorenzi, 1986)
- bromacil (post-emergence; Lorenzi, 1986)
- chlorimuron (pre- and post-emergence; Lorenzi, 1986)
- cycloate (pre-plant; Burgert et al., 1973)
- cyanazine (pre-emergence; Lorenzi, 1986; Dastghieb et al., 1995)
- dicamba (post-emergence; Lorenzi, 1986)
- diuron (presowing; Ivens, 1968)
- 2,4-D (seedlings only; Ivens, 1968)
- EPTC (pre-plant; Burgert et al., 1973)
-ethofumesate (post-emergence; Bouverat-Bernier and Gallotte, 1989)
- imazaquin (seedlings; Lorenzi, 1986)
- ioxynil (seedlings; Lorenzi, 1986)
- lactofen (seedlings; Lorenzi, 1986)
- linuron (pre-emergence; Lorenzi, 1986)
- MCPA (seedlings only; Ivens, 1968)
- metobromuron (pre-emergence; Laureti, 1988)
- metribuzin (pre-emergence; Dastghieb et al., 1995)
- paraquat (post-emergence; Ivens, 1968)
- prometryne (post-emergence; Bouverat-Bernier and Gallotte, 1989)
- simazine (pre-sowing; Ivens, 1968; nurseries; Gilchrist, 1988)
- terbacil (seedlings; Lorenzi, 1986)
- terbuthylazine (pre-emergence; Dastghieb et al., 1995)
- trifluralin (pre-sowing; Bouverat-Bernier and Gallotte, 1989)

Hamilton (1997) lists 25 herbicides registered for use against S. nigrum in Australia.

The bacterial-based herbicide pyrithiobac sodium has also been shown to be effective against S. nigrum at the 2-3 leaf stage in cotton by Vargas et al. (1996).

Herbicide resistance

Resistance to regularly-applied herbicides has developed in Solanum nigrum agg. in many locations worldwide, including:

-in China to atrazine (Zhu et al., 1986)
- in Malaysia to paraquat (Itoh et al., 1992)
- in Spain to triazines (Prado et al., 1993)
- in Denmark to atrazine (Andreason and Jensen, 1994)
- in South-East Asia to paraquat (Itoh and Ito, 1994)
- in Poland to triazine herbicides (Ciarka and Gawronski, 1996)
