摘要

低温胁迫是制约作物产量和品质的主要非生物胁迫之一。在25/15°C和5/4°C的昼夜处理条件下,测定耐冷水稻品种Koshihikari(粳稻亚型)和易感水稻NMR2(籼稻亚型)的幼苗生长参数、酚类物质含量和抗氧化活性。结果表明,在所有处理中,MNR2的根长、茎长、叶重和根重均比光处理受到更大程度的抑制。结果表明,在光光叶中鉴定出咖啡酸、香兰素、阿魏酸、辛酸、苯甲酸、鞣花酸和肉桂酸等7种酚酸,而在MNR2叶中只鉴定出苯甲酸和鞣花酸。相比之下,光光根中只检测到香草酸和鞣花酸,而MNR2根中检测到鞣花酸和肉桂酸。研究发现,水稻在低温胁迫下降低了酚酸含量,提高了总酚含量(TPC)和总黄酮含量(TFC),提高了抗氧化活性水平,但粳稻和籼稻亚型之间的响应程度有所不同。抗性水稻具有更多的结合类黄酮、酚类物质和酚酸,而易感水稻在降低温度下积累了更多的游离TPC和TFC。本研究结果强调,在低温胁迫下,酚类成分以酚类、多酚类和类黄酮的结合形式在水稻植株中可能比酚酸发挥更积极的作用,但需要进一步研究。

Responses of Flavonoids, Phenolics, and Antioxidant Activity in Rice Seedlings between Japonica and Indica Subtypes to Chilling Stress
Chilling is one of the major abiotic stress which limites yield and quality of many crops. The seedlings of rice varieties namely Koshihikari (Japonica subtype) chilling tolerant, and the susceptible NMR2 (Indica subtype) were treated at 25/15 °C and 5/4 °C day/night to determine the growth parameters, phenolic contents, and antioxidant activity. It was found that in all treatments, the growth of MNR2 including root and shoot lengths, and leaf and root weights were inhibited at greater levels than Koshihikari. There were seven phenolic acids identified in leaves of Koshihikari including caffeic acid, vanillin, ferulic acid, sinapic acid, benzoic acid, ellagic acid, and cinamic acid, but only benzoic acid and ellagic acid were found in leaves of MNR2. In contrast, only vanillic acid and ellagic acid were observed in roots of Koshihikari, whilst ellagic acid and cinnamic acid were found in roots of MNR2. It was found that rice reduced amount of phenolic acids but promoted quantity of total phenolic content (TPC) and total flavonoid content (TFC) and level of antioxidant activity in chilling stress, although the level of responses varied between Japonica and Indica subtypes. Tolerant rice possessed greater bound flavonoids, phenolics and phenolic acids, but susceptible rice accumulated greater free TPC and TFC in reduced temperature. Findings of this study highlighted that phenolic constituents in bound forms of phenols, polyphenols, and flavonoids may play an active role in rice plants than phenolic acids under chilling stress but need further elaboration.
