Study on seed morphology and seedling growth of Jatropha curcas L. From different provenances
The seed morphology and seedling growth of Jatropha curcas L. from 22 different provenances were studied. Eight indexes were investigated, including thousand seed weight, seed length, width, lateral diameter, seed length and width ratio, seedling height, ground diameter and emergence rate. The results showed that seed morphology, emergence rate and seedling height had significant variation among locations, while no significant differences were among ground diameter. The seed morphology showed longitudinal change. Seed emergence was influenced by seed quality. The seed morphology was no significant differences with seedling height and ground di-ameter. According to the cluster analysis of seed morphology, the natural range of Jatropha curca L. from 22 different provenances could be divided into 3 districts. The result indicates provenance selection has great potentiality.
