外源NO和H2O2诱导不同颜色马铃薯花青素积累
Exogenous NO and H2O2 Induced Anthocyanin Accumulation of Different Colors Potatos
摘要
Abstract
Taking different colors potatos ( Solarium tuberosum L.) 'Longshu No. 8', 'Longshu No. 7', 'LC310-2' and ' Shandongcairou' as materials, this experiment studied on anthocyanin accumulation and related enzyme activities of potato tuber after treatment of water, 0.1 mmol o L-1 SNP, 0.25 mmol oL-1 H2O2, 0.1 mmol -L-1 SNP+0.25 mmol -L-1 H2O2 in the period of starch. The results showed that after exogenous NO and H2O2 treatments, the anthocyanin contents in four geno-types potatos tuber's skin and flesh were increased, and the activities of PAL, PPO and CHI were strengthened. The inductive effect is 0.1 mmol o L-1 SNP+0.25 mmol o L-1 H2O2>0.25 mmol o L-1 H2O2>0.1 mmol o L-1 SNP>clear water ( CK ), indicating that NO and H2O2 treatments could accelerate anthocyanin synthesis and had additive effect.关键词
