Abstracts |
A study was conducted to investigate whether the daughter tubers formed from tubers that were formed from the protocorms of Habenaria radiata [Pecteilis radiata] gel covered and inoculated with orchid mycorrhizal fungi grew larger than the tubers formed from seedlings, whether these daughter tubers had the possibility of forming flower buds or reaching bloom in habitat, and whether the orchid mycorrhizal fungi in habitat was effective in promoting larger tuber formation. It was considered that one-half of tubers could form flower buds or reached bloom when the tuber weight of H. radiata reached beyond 150 mg. The daughter tubers grew larger than the tubers formed from seedlings, and the growth rate of the daughter tubers in habitat was two-fold larger. Therefore, the daughter tubers were thought to have the possibility of forming flower buds or reaching bloom after approximately five years. Because orchid mycorrhizal fungi which promotes tuber formation of H. radiata was recognized in habitat, it is considered desirable to inoculate this fungi on gel covered protocorms. Further, it was thought that environmental conditions must be investigated to enlarge the daughter tuber in habitat by methods in addition to the growth-promoting effect of mycorrhiza which also lives in habitat. |
