On Correlation of the Leaf Epidermal Structure of Ribes sp. and the Resistance to Infection of Cronartium ribicola

  • The leaf anatomical structure of 10 provenances of Ribes sp. sampled from 7 typical incidence sites of Pinus parviflora blister rust disease was studied. It was showed that there was a significant difference on the structure of the leaf epidermis between the samples of susceptible provenances and the resistant ones. The major difference existed on the thickness of the cuticle and the epidermis. The leaf epidermis and the cuticle of the resistant provenance samples were both evidently thicker than those of the susceptible provenance samples. The results suggested that there be significant correlation between the resistance to blister rust disease caused by Cronartium ribicola and the thickness of leaf epidermis of Ribes sp..
