Abstract:
The characteristics of blossoming and seed bearing of Qiongzhuea tumidinoda stand were studied in the paper. The results showed that: The distribution of blooming stand was sporadic and spotted,and blooming area was 62~667 m2 per plot. In addition,the area of blossoming stands would be larger and larger year by year. Blooming date started in the last ten days of March, flourishing blooming date began in the early part of April and seed maturating was in the last ten days of April, then the ramet tended to be dead. The rhizomes of blossoming clone changed the color from bright yellow to henna and puce,afterwards it began to rot gradually. The phenomena of sporadic blosso- ming was a synthesis representation of earlier blossoming because one or several clones lacked nutri- tion resulted from locally repeated jamming,but it followed the periodicity theory as a prerequisite.
