对特爆2号喷施外源激素6-BA，研究不同浓度6-BA对爆裂玉米籽粒胚乳细胞增殖、籽粒增重以及营养物质充实的影响。结果表明，6-BA显著提高籽粒的胚乳细胞数和粒重，浓度越高差异越显著；6-BA处理对胚乳细胞大小有一定程度的提高作用，但与对照相比无显著差异。授粉后10 d，6-BA处理对籽粒蔗糖和淀粉含量影响并不显著，但显著提高蛋白质含量；授粉15 d以后，6-BA处理籽粒蔗糖、支链淀粉和总淀粉含量明显高于对照，但不同浓度6-BA处理间并没有显著差异；蛋白质含量在授粉20 d以后差异较大，表现为60 mg/L＞10 mg/L＞0 mg/L（CK）。本试验中，喷施6-BA可获得较高的粒重和籽粒营养物质积累。

The effects of spraying 6-BA on the proliferation of endosperm cell , grain weight increase and nutrient accumulation of pop corn were studied with the variety Tebao 2 as test material .The results showed that spraying 6-BA could significantly increase the number of endosperm cell and grain weight;and the higher the concentration was ,the more significance was .The endosperm cell size also could be increased , but there were no significant differences compared to the check .The application of 6-BA had no significant effects on the content of sucrose and starch , but significantly increased the protein content at the 10 th day after pollination;after 15 days of pollination , the content of sucrose , amylopectin and total starch were obviously higher than those of CK , but there were no significant differences between different concentrations of 6-BA. The protein content had larger differences between different concentrations after 20 days of pollination ,showing 60 mg/L﹥10 mg/L﹥0 mg/L( CK) .In conclusion , spraying 6-BA could obtain higher grain weight and nutrient accumulation .
