[Analysis of catharanthine content and agronomic traits in Catharanthus roseus].
Catharanthine content and agronomic traits in major Catharanthus roseus varieties were analyzed. It was found that there existed great difference in catharanthine content and agronomic traits among the varieties. Catharanthine content was the highest in variety Pacifica Polka Dot (PPD), reaching 3.79 mg g(-1) dry leaf weight, and the lowest in variety Cooler Pink (CP) with only 0.9 mg g(-1) dry leaf weight. Correlation existed in certain extent between catharanthine content and agronomic traits in C. roseus. Path analysis showed that among all the agronomic traits analyzed, internodal distance positively affected catharanthine content at significant level (P<0.05), with the path coefficient being 1.473. This study provides useful information for high-catharanthine content C. roseus introduction and breeding.
