Quantitative Variations on Floral Organs of Oriental Lily

The quantitative variations on floral organs from 3 varieties of Oriental Lily planted in a greenhouse were observed for comparison. There was a total of 58 variations found, but few was common among the 3 varieties of the flowering plants. The tepals normally numbered between 2 and 8, and Sorbonne tended to have the highest count. On Sorbonne and Fastrada, the gradual changes on the number of stamen-petaloid were mainly observed on the reduction of anthers, which could be seen from the variation on the floret count. The variation on Fastrada mainly showed in the increased number of tepals. On tepal and stamen, Siberia had the highest frequencies of a same count, and more than half of them were on an increasing trend. The large variations meant an inconsistency on the floral quality. But, at the same time, they also provided abundant choices for breeding and studies on the lilies.
