- 摘要:
- 为研究不同酚酸物质对玛咖发芽的影响,本试验以黑色和黄色玛咖为试材,用不同浓度的乙酸(5,10和15 mmol·L-1)和丙酸(0.5,1.0,2.0和4.0 mmol·L-1)溶液对玛咖种子进行处理,分别测量玛咖种子的发芽率、发芽势、发芽指数和胚芽生长情况。结果表明:与CK相比,经乙酸处理的黑色和黄色玛咖种子,随乙酸浓度的增加抑制种子萌发的作用逐渐增强、芽长变短。同时,低浓度的丙酸(0.5~1.0 mmol·L-1),对玛咖的发芽率有一定的促进作用,随着丙酸浓度的逐渐增大,玛咖种子的发芽率逐渐下降、芽长生长受到抑制。另外,黑色与黄色玛咖相比,黄色玛咖芽长的生长对乙酸的适应性更强,而黑色玛咖芽长的生长对丙酸的适应性更强。
- Abstract:
- In order to study the effects of different phenolic acids on the germination of maca.In this paper,black and yellow maca seeds were treated with different concentrations of acetic acid(5,10 and 15 mmol·L-1) and propionic acid(0.5,1.0,2.0 and 4.0 mmol〖·L-1).The germination rate,germination potential,germination index and germ growth of maca seeds were measured.The results showed that,compared with CK,the germination inhibition of black and yellow maca seeds treated with acetic acid increased with the increase of acetic acid concentration,and the bud length became shorter.At the same time,low concentration of propionic acid(0.5-1.0 mmol·L-1) could promot the germination rate of maca.With the increase of propionic acid concentration,the germination rate of maca seeds decreased and the growth of bud length was inhibited.In addition,black maca compared with yellow maca,the growth of yellow maca bud length was more adaptable to acetic acid,while the growth of black maca bud length has stronger adaptability to propionic acid.
