摘要
以牛角椒品种农城椒１号为试材，探讨了聚乙烯醇（ＰＶＡ）渗调处理对辣椒种子活力及芽期过氧化物酶（ＰＯＤ）、超氧化物歧化酶（ＳＯＤ）活性的影响。结果表明，在１８℃条件下，辣椒种子经０．５％～２．０％ＰＶＡ渗调处理１２～４８ｈ后，发芽率、发芽势、发芽指数均有所提高，种子浸出液相对电导率降低，芽期ＰＯＤ、ＳＯＤ活性增强，ＳＯＤ活性的峰值提前，其中以１．５％ＰＶＡ渗调３６ｈ效果最好。
Effects
of polyvinyl alcohol (PVA) priming on the increase of pepper seed vigour and activity of
peroxidase (POD) and superoxide dismutase (SOD) during the seed germination with the tested
material cv.'Nongchengjiao No.1' were discussed in this paper. The results indicated that
germination percentage, germinating viability and seed vigour of pepper seeds were increased,
and the relative electric conductivity of seed extract solution was decreased when pepper
seeds were primed in 0.5%￣2% of PVA solution at 18 for 12-48 h. Comparison with unpriming
seeds, the activity of POD and SOD was increased in priming seeds during the seed
germination.The highest value of activity of SOD appeared earlier in priming seeds than that in
unpriming seeds. The best result was obtained in the treatment of 1.5% of PVA solution priming
36 h.\;
