Role of allelochemicals and trichome density in the resistance of tomato to whitefly Ciência e Agrotecnologia
Neiva,Irã Pinheiro; Andrade Júnior,Valter Carvalho de; Maluf,Wilson Roberto; Oliveira,Celso Mattes; Maciel,Gabriel Mascarenhas.
In Brazil, the tomato is cultivated in almost all geographic regions even though its yield is significantly reduced by pests and diseases. Among these pests and diseases, whitefly is a major problem that causes direct and indirect damage due to its role in transmission of geminiviruses. The aim of the present study was to compare the degree of resistance to the silverleaf whitefly of tomato plant lines rich in acyl sugars (AS), zingiberene (ZGB), and 2-tridecanone (2-TD) and to establish whether selection for strains with higher densities of glandular trichomes promotes sufficient resistance to this insect pest. The investigated lines were developed by performing back-crossings in tomato (Solanum lycopersicum) from the interspecific crossing of S....
