- 摘要:
- 以采后辣椒为试材，采用不同光质（绿光、UV-A、红光和UV-C）处理的方法，研究了不同光质对采后辣椒叶绿素含量、类胡萝卜素和花青素含量的影响，以期为采后辣椒果实转色与调控研究提供参考依据。结果表明：低温红光处理可以快速促进辣椒转色，处理10 d转色率达到90%以上，处理15 d果实中的花青素含量以及类胡萝卜素中的新叶黄素、辣椒红素、β-隐黄质素、玉米黄素和β-胡萝卜素含量保持最高水平，而低温黑暗处理下辣椒叶绿素和叶黄素含量保持最高水平，相关性分析表明辣椒果实转色率与叶绿素、叶黄素呈显著负相关，而与花青素、辣椒红素等指标呈显著正相关。
- Abstract:
- Taking postharvest chili peppers as the test material,different light qualities (green light,ultraviolet A,red light,and ultraviolet C) were applied to investigate their effects on the chlorophyll,carotenoid,and anthocyanin contents in postharvest chili peppers,in order to provide references for research on color transformation and regulation in postharvest chili pepper fruits.The results showed that low-temperature red light treatment rapidly promoted pepper color transformation,achieving a color change rate of over 90% after 10 days.After 15 days of treatment,the contents of anthocyanins and carotenoids (including neoxanthin,capsanthin,β-cryptoxanthin,zeaxanthin,and β-carotene) in the fruits increased significantly.In contrast,the contents of total chlorophyll and lutein remained the highest under low-temperature dark treatment.Correlation analysis showed that the fruit color change rate was significantly negatively correlated with total chlorophyll and lutein contents,but significantly positively correlated with anthocyanin,capsanthin,and other indicators.
