[Method] With four varieties of G. elata （Wu G. elata, Hong G. elata, Lv G. elata, Wu-Hong G. e/ata） as test matedals, box planting method and capillary electrophoresis determination were used to conduct the comparative analysis on the planting effect and biochemical fingerprint of four varieties of G. elata which were planted in the same conditions. [Result] There were no significant differences in the number of juvenile tubers after planting for 5 months, and the variety with the best growth potential was Hong G. elata. At 17 months after cultivation, there were no significant differences in the number of im- mature tubers, but the difference in the weight of immature tubers reached the significant level among the 4 varieties, among which Hong G. elata had the largest weight with the average reaching 3 042.20 g. After planting for 17 months, immature tubers of the 4 varieties were determined using capillary electrophoresis, and 4 large peaks were obtained on the maps, in which the 4th peak and the 1st peak had significant specificity. The 4th peak and 1st peak area ratio of Wu G. elata BI. was greater than or equal to 1, showing no intraspecific variation. [Conclusion] The study on the suitable growth environment and variation occurrence period of G. elata could provide theoretical basis for icultivation of G. elata.展开更多
