Quantifying seed germination responses to low temperatures: Variation among Lycopersicon spp.

Environmental and Experimental Botany, 1985
Abstract Seed germination response to a range of low temperatures (6–20°C) was quantified for six accessions of Lycopersicon spp. representing the cultivated tomato L. esculentum (Mill.) and wild relatives L. peruvianum (Mill.) and L. chilense (Dun.).

Cold tolerance in tomato. II. Early seedling growth of Lycopersicon spp.

Physiologia Plantarum, 1986
Hypocotyl and root growth elongation of etiolated seedlings was measured non‐destructively for the wild tomato accessions LA 460 (Lycopersicon chilense Dun.), PI 126435, PI 127831 and PI 127832 (L. peruvianum Mill.) and controls PI 120256 and T3 (L. esculentum Mill.) on slant boards at 10, 15 and 20°C.

Survival and Development of Fruit Borer, Heliothis Armigera (Hübner), (Lepidoptera: Noctuidae) on Lycopersicon Spp.

International Journal of Tropical Insect Science, 1990
Nineteen accessions from seven Lycopersicon species were bioassayed for their resistance to Heliothis armigera (Hubner) (Lepidoptera: Noctuidae) in laboratory tests at 29 ± 1°C and 65 ± 2% r.h. Data on larval developmental duration (days), survival (%) and pupal weights (mg) revealed that maximum resistance to H.

Identification of DNA markers linked to fusarium wilt resistance in tomato (Lycopersicon spp.)

2023
Fusarium wilt caused by the fungus Fusarium oxysporum f sp. lycopersici is a disease of tomato (Lycopersicon esculentum Mill.) with major economic importance. The most practical form of controlling this disease is through genetic resistance from related germplasm.

Screening of Lycopersicon spp. for glyphosate and/or Orobanche aegyptiaca Pers. resistance

Weed Research, 1988
SummaryA major screening programme was conducted to determine which Lycopersicon spp. (if any) have practical levels of resistance to glyphosate; the same lines were also tested for resistance to Orobanche aegyptiaca. A majority of the lines investigated showed high susceptibility to glyphosate applied at 37⋅5 g a.i.

Competitive interactions of tomato (Lycopersicon esculentum) and nutsedges (Cyperusspp.)

Weed Science, 1997
Replacement series experiments were conducted under greenhouse conditions to evaluate effects of population densities and proportions on the intraspecific and interspecific interference of either purple nutsedge or yellow nutsedge with tomato cv. Sunny, under nonlimiting conditions of water and nutrients.

Biochemical aspects of reactive oxygen species formation in the interaction between Lycopersicon spp. and Oidium neolycopersici

Physiological and Molecular Plant Pathology, 2006
Abstract Three Lycopersicon spp. accessions differing in the level of resistance to Oidium neolycopersici L. Kiss (tomato powdery mildew) were studied. Defence reactions occurring in tissue of Lycopersicon esculentum cv. Amateur (susceptible control), Lycopersicon hirsutum f.

Salt tolerance in Lycopersicon spp. VII. Pleiotropic action of genes controlling earliness on fruit yield

Theoretical and Applied Genetics, 1999
The change from vegetative to reproductive development (earliness) in Lycopersicon chesmannii line L2 was delayed for 20 weeks when compared to other Lycopersicon species under greenhouse conditions. The interspecific hybrid of L. chesmannii L2 and L. esculentum E9, a cherry tomato cultivar, also showed this delay in reproductive development.

Pigweed (Amaranthus spp.) interference in transplanted tomato (Lycopersicon esculentum)

Journal of Horticultural Science, 1992
Interference of redroot pigweed (Amaranthus retroflexus L.) and prostrate pigweed (Amaranthus blitoides L.) in transplanted tomato (Lycopersicon esculentum Mill ‘GS12’) was studied in two field experiments in 1990 and 1991. Final yield was unaffected when the naturally occurring Amaranthus spp (mostly A. blitoides) were allowed to interfere with tomato
