摘要: 以慈竹为材料,研究不同浓度和配比的GA3和IAA对综纤维和叶绿素含量动态积累的调控效应,为纸浆用竹的遗传改良研究提供理论依据。研究结果表明, GA3和IAA处理对慈竹综纤维动态积累调控作用具有差异。处理前30 d内,GA350IAA200处理慈竹综纤维积累强度高于GA3200IAA50处理,40~50 d时,则反之。GA3和IAA处理的综纤维最终水平明显高于空白对照,差异达极显著水平。GA3和IAA处理能提高慈竹叶绿素含量,GA3200IAA50处理慈竹叶绿素含量高于GA350IAA200处理。相关分析结果表明,叶绿素含量与综纤维含量间呈不显著正相关关系。

Abstract: The effects of GA3 and IAA with different concentrations and combinations on the dynamic accumulation of holocellulose and chlorophyl content in Neosinocalamus affinis were studied. The objective of the study is to provide theoretic basis for genetic improment of bamboos used in pulp industries. The results showed that the effects of GA3 and IAA with different concentrations and combinations on the dynamic accumulation of holocellulose content were different. In 30 days after the treatments, the accumulation intensity of holocellulose was much higher under the GA350IAA200 treatment than under the GA3200IAA50 treatment. The result was inverse after 30 days (40 to 50 days). The final results revealed that the content of holocellulose was significantly higher at 0.01 level under the GA3 and IAA treatments than under the control treatments. GA3 and IAA were generally capable of improving the accumulation of chlorophyl content. The chlorophyl content in GA3200IAA50 was higher than that of GA350IAA20 treatments. The results of correlation analysis showed that the relationships of chlorophyl content with holocellulose content were not significant and positive.
