Effect of Spraying Exogenous Substances on Scion Growth of Camellia oleifera
Annotatsiya
The effects of spraying different exogenous substances( plant growth regulators,foliage fertilizer) on the scion growth of Camellia oleifera in cutting orchard were observed. The results showed that the degree of scion lignification in treatment 8( spraying NAA 2000 mg/L) and treatment 10( spraying biogen 400-times dilution) was significantly higher than that in control. The scion yield and quality of Camellia oleifera were significantly influenced by different treatments,and treatment 1 ~ 3( spraying GA 3 500 ~ 1500 mg / L) acquired the best effects. In treatment 1 ~ 3,the quality indexes( such as length,width) of the scion were significantly better than those in control and other treatments; the scion section spacing was reasonable too,thus the utilization rate and yield of the scion were higher. There were significantly positive correlations between any two indexes( except for the number of buds per scion,and scion section spacing).
