Abstract

Investigations on canker development in six cocoa genotypes showed IMC 67 to be resistant, ICS 1, TSH 1188 moderately resistant and TSH 1076, SCA 6 and P 18 as susceptible. Plant wound-healing components (lignin, callose and suberin) were detected in healthy, wounded and wound-inoculated (Phytophthora palmivora) tissues of all the genotypes, although at different rates. Lignin concentration was negatively correlatedwith canker lesion size and positively correlated with time of complete healing. A strong positive correlation was also observed between time of healing and lesion size. The rate of healing of uninoculated wounds was fastest in IMC 67, moderate in ICS 1 and TSH 1188 and slowest in TSH 1076, SCA 6 and P 18 while cessation of lesion expansion was observed al 6 weeks in IMC 67, 8 in ICS 1, TSH 1188 and 10 in TSH 1076, SCA 6 and P 18. This study revealed that lignification plays a role inwound-healing and consequently a role in resistance of coca stems to P. palmivora infection.
