Observations on Flowering Reversion of Rhododendron fortunei
Observations were conducted on flowering reversion of young and adult Rhododendronfortunei in Tiantai,Zhejiang province.The result demonstrated high proportion of flowering reversion in the early development of floral buds of Rh.fortunei,with the inflorescence reversion being the mainly type.Statistics analysis showed the exploded buds rate of young trees,especially of that planted in the low-altitude(16.82％) was higher than that in the natural conditions (10.42％).The exploded rate of adult trees was only 4.17％ under the natural condition.Removal of young fruits (unfertilizred) could significantly increase the occurrence rates of floral bud (from 48.9％ to 54.6％),exploded rate was not significant.But when the adult trees were fertilized,removal of young fruits would increase exploded rate to 9.09％.The observations resulted that age,climate and nutritional status of each tree were major factors of the explosion bud.And the nutrients may be excessive accumulated.
