Morphological differences in Houttuynia cordata from 23 different provenances in China

    Corresponding author: SI Jin-ping

Abstract: To reveal the morphological variation in the main producing areas in China,eight characteristics of the leaves,flowers,fruits,and stems of Houttuynia cordata,namely fructescence length,diameter,and stalk length;flower or fruit number per plant;capsule number;seed number;plant height;and ground diameter;from 23 different provenances were investigated. Then the relationship between them or geographic origin was studied by analysis of correlation. The division of types based on cluster analysis. Results showed major differences(P<0.01) for the eight characteristics within provenances with flower or fruit number per plant varying most(RSD = 82%) followed by plant height and seed number. Meanwhile,morphological characteristics were correlated with each other significantly(P<0.05 or P<0.01). Furthermore,according to the main morphological characteristics of leaves and stems,the 23 provenances could be divided into two types. Therefore,morphological characteristics of H. cordata have a certain genetic basis allowing for a feasible division by type. Nevertheless,when breeding for excellent cultivars of H. cordata more comprehensive factors should be considered.[Ch,1 fig. 4 tab. 6 ref.]
