The effect of chilling temperatures upon cell cultures of tomato (Lycopersicon esculentum Mill cv ;VF36,' and cv ;VFNT Cherry,' and L. hirsutum Humb. & Bonpl.) was tested. Doubling times for L. esculentum were 2 to 3 days at 28 degrees C, and 3 to 8 days at 12 degrees C. No growth was observed at 8 degrees C, indicating an abrupt limit to growth between 8 and 12 degrees C. Fluorescein diacetate...

Root-knot nematodes ( Meloidogyne spp.) are among the main pathogens of tomato ( Lycopersicon esculentum ) worldwide. Plant resistance is currently the method of choice for controlling these pests and all the commercially available resistant cultivars carry the dominant Mi gene, which confers resistance to the three main species Meloidogyne arenaria , M. incognita and M. javanica . However the ...

Present study aimed for in vitro culture of circinate part of young leaves of D. esculentum which is amongst the leafy vegetables consumed as vegetable by Paniya and Chetti tribes of Western Ghats. The circinate part of young leaves (crosiers), excised before the beginning of foliar expansion, was inoculated on half strength Murashige and Skoog (MS) medium supplemented with auxins indole-3-buty...

The effects of wild germplasm on tomato fruit shelf life have not yet been completely evaluated. Three different genotypes of Lycopersicon esculentum (a cultivated variety, a homozygote for nor and a homozygote for rin), LA1385 of L. esculentum var. cerasiforme, LA722 of L. pimpinellifolium, and 10 diallel hybrids were assayed. Mean values of fruit shelf life, weight, shape, and mean number of ...

The study aimed to evaluate nutraceutical potential of three commercially significant edible jellyfish species (Acromitus hardenbergi, Rhopilema hispidum and Rhopilema esculentum). The bell and oral arms of these jellyfishes were analyzed for their proximate composition, calorific value, collagen content, amino acid profile, chemical score and elemental constituent. In general, all jellyfish po...

F(1) hybrids between the cultivated tomato (Lycopersicon esculentum) and the wild nightshade Solanum lycopersicoides are male sterile and unilaterally incompatible, breeding barriers that impede further crosses to tomato. Meiosis is disrupted in 2x hybrids, with reduced chiasma formation and frequent univalents, but is normal in allotetraploid hybrids, indicating the genomes are homeologous. In...
