- 摘要:
- 为了探究铝胁迫对植物生长发育的影响，以萝卜(Raphanus sativus L.)为材料，用不同浓度（0、10、20、30、40、50、60 mg·L-1）铝溶液培养萝卜幼苗。结果表明：在不同浓度铝溶液的胁迫下，蛋白质含量随Al3+浓度的升高先增加后减少；铝胁迫会促进叶绿素的合成，当铝溶液浓度为10 mg·L-1时促进作用最明显，而且叶绿素含量的变化会使可溶性糖的含量受到影响；浓度为30 mg·L-1的铝溶液培养的萝卜幼苗核酸含量相对较少，受核酸含量的影响，萝卜幼苗在铝溶液浓度为30 mg·L-1时最矮。
- Abstract:
- In order to explore the effects of aluminum stress on the growth and development of plant,the radish (Raphanus sativus L.) was used as the material,and the radish seedlings were cultured indifferent concentrations (0,10,20,30,40,50 and 60 mg·L-1).The results showed that under the stress of different concentration of aluminum,the protein content first increased and then decreased.Aluminum stress promoted the synthesis of chlorophyll,the effect was most obvious when aluminum concentration was 10 mg·L-1,and the change in chlorophyll content would also affect the content of soluble sugar.When the concentration of aluminum solution was 30 mg·L-1,the nucleic acid content of radish seedlings was relatively low,and the radish seedlings were the lowest.
