Development of Bemisia tabaci (Gennadius,1889) biotype B on Lycopersicon spp. genotypes

Scientia Agricola, 2002
Whiteflies are phytophagous insects, whose nymphs and adults suck the phloem sap, causing direct damage due to host plant weakness. In tomato (Lycopersicon spp.) crops, they are important vectors of limiting fitoviruses.

288 STUDY OF THE ALLELOPATHIC PROPERTIES OF LYCOPERSICON HIRSUTUM [PDF]

HortScience, 1994
Laboratory experiments were conducted to evaluate the relationship between leaf area, leaf number, dry weight, and mg extract of Lycopersicon hirsutum (LA 1777) leaf washes and germination or root growth of common purslane (Portulaca oleracea) seeds. Additional experiments were conducted to determine the relationship between L.

Physical Properties of Mitochondrial Lipids from Lycopersicon hirsutum [PDF]

Plant Physiology, 1982
Mitochondrial lipids from Lycopersicon hirsutum undergo a broad thermal transition beginning well below 0 degrees C and ending at approximately 25 degrees C. Differential thermal analysis of mitochondrial lipids isolated from ecotypes of L. hirsutum that differ in chilling sensitivity indicates that these lipid preparations have physically similar ...

Genetics of Hybrid Incompatibility Between Lycopersicon esculentum and L. hirsutum [PDF]

Genetics, 2005
Abstract We examined the genetics of hybrid incompatibility between two closely related diploid hermaphroditic plant species. Using a set of near-isogenic lines (NILs) representing 85% of the genome of the wild species Lycopersicon hirsutum (Solanum habrochaites) in the genetic background of the cultivated tomato L.

Mapping and characterization of novel parthenocarpy QTLs in tomato [PDF]

, 2008
Parthenocarpy is the development of the fruit in absence of pollination and/or fertilization. In tomato, parthenocarpy is considered as an attractive trait to solve the problems of fruit setting under unfavorable conditions.

Temperature and Photoperiod Influence Trichome Density and Sesquiterpene Content of Lycopersicon hirsutum f. hirsutum [PDF]

Plant Physiology, 1992
Resistance to Colorado potato beetle in a clone of Lycopersicon hirsutum f. hirsutum L. is attributed to the presence of the sesquiterpene zingiberene in the type VI leaf trichomes; however, both day/night temperature regimen and photoperiod affect zingiberene content and trichome density.
