Abstract
Abstract The effects of different levels of fertilization with nitrogen and potassium (NK), height within the canopy and plant age of Lycopersicon hirsutum f. glabratum (PI 134417) C. H. Mull and L. esculentum on the density of foliar cristalliferous idioblasts and trichomes, and on the levels of 2‐ tridecanone (2‐TD) and 2‐undecanone (2‐UD) and their influence on the resistance to Myzus persicae (Sulzer) were investigated. NK levels were inversely related to densities of trichomes and cristalliferous idioblasts in L. esculentum , but only to densities of cristalliferous idioblasts in L. hirsutum . Trichome density increased with increasing height within the canopy and with plant age in L. esculentum and L. hirsutum . Density of cristalliferous idioblasts in L. hirsutum increased with canopy height reaching a maximum at mid‐height within the canopy in opposition to L. esculentum in which a small decrease in density with height within the canopy was found. There was also a small decrease of idioblast density with increasing plant age for L. esculentum , while a greater and opposite variation took place in L. hirsutum. L. esculentum has mainly non‐ glandular leaf trichomes (90%), while L. hirsutum has mainly glandular trichomes (97%). The main glandular trichomes of L. hirsutum are producers of 2‐TD and 2‐UD, whose leaf content increases with increase of trichome density. A negative effect of 2‐TD concentration and cristalliferous idioblast density on the survival and longevity of M. persicae was observed. Since L. hirsutum presented much higher levels of 2‐TD and cristalliferous idioblast density than L. esculentum, L. hirsutum seems a promising source of resistance to M. persicae for tomato breeding programs.
