“…The second non-glandular trichome producing Solanaceous species was silver leaf nightshade ( S. eleaegnifolium ) [14], a herbaceous perennial native to southwestern United States [22], which has become highly invasive in countries including Morocco, Australia, and Greece [23,24]. Plants used in this study were derived from populations in mainland Thessaloniki and the island of Lesvos, Greece.…”

Leaf trichomes play well-established roles in defense against insect herbivores, both as a physical barrier that impedes herbivore movement and by mediating chemical defenses. However, little work has examined how different trichome types influence herbivory by herbivores at different stages of development. We examined whether caterpillar instar and trichome type (glandular or non-glandular) affected the ability of the specialist herbivore caterpillar Manduca sexta to initiate feeding on 11 Solanaceous species exhibiting variation in the density and type of leaf trichomes. Our results suggest that non-glandular trichomes are far more effective than glandular trichomes in deterring the initiation of feeding by first- and second-instar caterpillars. Meanwhile, neither glandular nor non-glandular trichomes significantly affected the ability of third-instar caterpillars to commence feeding. These findings suggest that while non-glandular trichomes deter feeding initiation by early instar caterpillars, the contribution of both trichomes on later instars may depend on effects after feeding initiation.

“…One single plant produces during the summer 40-60 spherical fruits. The immature berries are green and fleshy, but get dry when ripe and turn a yellow or black colour (Boyd, Murray, & Tyrl, 1984;OEPP, 2007). The use of trompillo berries by Pima Indians for the manufacture of cheese was first described in 1916 (Bodansky, 1916).…”

The berries of Solanum elaeagnifolium (trompillo) have been used since ancient time in Chihuahua, Mexico, as a milk coagulant in cheese making. This article describes an approach to the characterization of the plant coagulant from trompillo. From the main results, it was noticed that only the yellow berries of trompillo have proteolytic and milk-clotting activity. These activities were observed in the crude extracts (CEs) obtained from both seeds and fruit peels of yellow berries. The proteolytic activities of these CEs ranged from 6.0 to 8.5 U-Gly/mg, although the absence of NaCl in the CEs decreased their activities significantly. The milk-clotting activities of CEs from the berries of trompillo (4347-2564 MCA) were similar to those reported for other plant coagulants. Some CEs had a similar ratio of milkclotting activity/proteolysis as rennin and chymosin. This plant coagulant produced an unspecific hydrolysis on caseins, increasing the yield in fresh-type miniature cheese.Keywords: Solanum elaeagnifolium; plant coagulant; silverleaf nightshade; trompillo; fresh cheese Las bayas de Solanum elaeagnifolium (trompillo) se han utilizado por años en la elaboración de queso en Chihuahua, México. Este trabajo describe los avances en la caracterización del coagulante vegetal obtenido del trompillo. Se encontró que solo las bayas amarillas del trompillo presentaban actividad proteolítica y coagulante (en leche). Estas actividades se observaron en los extractos crudos (CE) obtenidos tanto de las semillas como de las cáscaras de los frutos amarillos. Las actividades proteolíticas de estos CEs fueron de 6.0 a 8.5 U-Gly/mg, aunque la ausencia de NaCl disminuyó significativamente su actividad. La actividad coagulante de los CEs obtenidos del trompillo (4347 a 2564 MCA) fueron similares a los reportados en otros coagulantes de plantas. Además, algunos CE presentaron un proporción de actividad coagulante/proteólisis similar al de la renina y quimosina. Finalmente, este coagulante vegetal produce una hidrólisis inespecífica en la caseína, incrementando el rendimiento en queso Fresco miniatura.

“…It is a known invasive plant in all countries of the Mediterranean Basin, Australia, Chile, India, New Zealand, Pakistan, Puerto Rico, South Africa, Taiwan and Zimbabwe (Bouhache and Tanji, 1985;Mekki, 2007). It is listed as a noxious weed in 21 states of the USA (Mekki, 2007;Roche, 1991) and it is a serious weed in many semi-arid areas of the world (Baye, 2007;Boyd et al, 1984). Once established, it is very difficult to eradicate as new sprouts can generate from creeping lateral roots, root fragments and rhizomes (Stanton and Lemerle, 2011;Westerman and Murray, 1994).…”

Control of silverleaf nightshade with glyphosate

Glyphosate should have a long-lasting effect against Solanum elaeagnifolium Cav. when its application timing coincides with active translocation of non-structural carbohydrates toward rootstock. A pot experiment was conducted from June 2012 to June 2013 to evaluate glyphosate activity against S. elaeagnifolium at three growth stages: early fruiting, green berries and ripened berries. Herbicide treatments were applied in a water volume equivalent to 200 L.ha-1 at a rate of 5 L.ha-1 (2025 g a.i. ha-1). The experimental design was a randomized complete block design with 10 replications. To assess glyphosate activity, S. elaeagnifolium height and numbers.plant-1 of leaves, flowers, berries and sprouts were measured at 0, 20, 30 and 60 days after treatment (DAT). Therefore, S. elaeagnifolium regeneration was monitored at April, May and June 2013. Glyphosate effect on leaves number.plant-1 was detected since 20 DAT. The reduction reached 90% at 60 DAT for glyphosate timing application at green or ripened berries. However, for early fruiting stage the decrease was not long lasting. Berries number.plant-1 decrease at 30 DAT was more for glyphosate application at green or ripened berries. Sprouts number in June 2013 was maximum for glyphosate application at early fruiting and the least for the green berries stage. Therefore, the most appropriate timing of glyphosate application is green berries growth stage.
