Abstract
[ Objective ] The theoretic basis of the management of the grape plantlet in vitro in light intensity and N-fertilization was provided.[ Method] The effect of the different light intensities and N-fertilizations( NH4 + -N and NO3- -N) on the growth/development and the physiological characteristic of plantlet in vitro grape variety Red Globe was researched. [ Results] The results showed that the content of chlorophyll in the plantlet was increased with the increment of the ratio of NH4 + -N in N-fertilization. The highest content of chlorophyll in the plantlet was reached under the condition of the light intensity of 5 000 lx and the ratio of NH4 +-N to NO3 - -N of 5:5. Under the same condition of N-fertilization the content of soluble sugar and protein was improved with the increment of light intensity. When the light intensity was 5 000 lx and the ratio of NH4 + -N to NO3 - -N was 0.8:9.2( based on the improved medium B5 ) ,the content of soluble sugar and protein was the highest in all treatments.[ Conclusion ] The following condition∶ the light intensity of 5 000 lx and the ratio of NH4 + -N to NO3 - -N of 0.8:9.2,was beneficial to the accumulation of the content of soluble sugar and protein.关键词
