- 摘要:
- 大田栽培条件下，以垦农4号为材料，通过叶面喷施不同浓度植物生长调节剂6苄基腺嘌呤（6-BA），比较叶片中总糖、可溶性糖、淀粉、还原糖、蔗糖和转化酶活性，研究不同浓度6-BA对大豆叶片碳代谢相关生理指标的影响。结果表明：两种浓度6-BA在全部取样期内均提高了大豆叶片中转化酶活性，喷药后40 d均极显著提高了大豆叶片中蔗糖含量，喷药后10～20 d和50～60 d均提高了大豆叶片中可溶性糖含量，喷药后20～40 d均提高了大豆叶片中淀粉含量，喷药后30～50 d均提高了大豆叶片中还原糖含量，且6-BA喷施量20 mg·L-1处理效果均好于10 mg·L-1处理。综合分析表明，叶面喷施不同浓度6-BA调控了大豆叶片中糖分含量和转化酶活性，改善了大豆叶片中碳代谢相关生理指标。
- Abstract:
- Taking soybean(Glycine max)cultivar Kennong 4 as material,three concentrations (0,10,20 mg·L-1) of 6-Benzyl adenine(6-BA) were leaf sprayed at R1,and soybean carbon metabolism relevant indicators,including total sugar,soluble sugar,starch,reducing sugar,sucrose,and invertase activity in leaves at 10,20,30,40,50 and 60 days after spraying(DAS). Applying 6BA increased invertase activity,sucrose content at 40 DAS,soluble sugar content at 10-20 and 50-60 DAS,starch content at 20-40 DAS,reducing sugar content at 30-50 DAS. The enhance effect of 20 mg·L-1 6-BA was better than 10 mg·L-1 6-BA. Results indicate applying 6-BA could regulate sugar content and increase the carbon metabolism related indicators of soybean.
