Abstract

Solanum berthaultii Hawkes bears trichomes reportedly providing resistance to insects. Results indicated that the density of types A and B trichomes was linearly related to the inverse of the leaflet area. The number of trichomes on the adaxial and on the abaxial surface of terminal leaflets was not affected by two levels of water stress or by growing conditions in the greenhouse or the field. The leaflets of the water-stressed plants were generally smaller and, consequently, the density of trichomes higher.

The survival of first-instar Colorado potato beetle larvae was similar on S. berthaultii grown under varying drought conditions and on leaves from field-grown plants bearing different densities of trichomes.

Résumé

Solanum berthaultii Hawkes porte des trichomes qui présumément, lui procurent une immunité contre les insectes. Une relation linéaire a été mise en évidence entre la densité des trichomes des types A et B et l’inverse de la surface des folioles. Le nombre de trichomes sur la surface supérieure et inférieure de la foliole terminale n’a pas varié lorsque les plantes furent soumises à des conditions de sécheresse ou à différentes conditions de culture en serre et au champ. Les folioles des plantes soumises à un stress hydrique étaient plus petites et par conséquence portaient une densité plus élevée de trichomes.

La survie des larves de premier stade du doryphore de la pomme de terre était la même lorsqu’ils étaient nourris avec des feuilles provenant de plantes de S. berthaultii ayant poussé sous différentes conditions de sécheresse, ainsi qu’avec des folioles portant différentes densités de trichomes et provenant de plantes cultivées au champ.
