| Abstract: | The contents of total nucleic acid and RNA and RNA/DNA rate were increased during flower bud differentiation in male and female trees of Torreya grandis. In comparision with leaf bud differentiation,there were high level of total nucleic acid and RNA in flower bud. There was higher rate of RNA/DNA in flower bud than that in leaf bud. The contents of total nucleic acid and RNA and RNA/DNA rate in leaves of female and male shoots during flower bud differentiation were also higher than that in the leaves of nutrient shoot and in the shoot before flower bud differentiation. The results of this paper show the relationship between nucleic acid and flower bud differentiation in T. grandis. The problem on accelerating flowering and fruiting by chemical regulating treatment is also discussed. |
