摘 要: 红色砂梨(Pyrus pyrifolia Nakai)原产于中国云南和四川南部,近年来已在全国各地引种栽培,但着色表现不佳,需开发着色调控技术以满足生产需要。本研究以红色砂梨‘满天红’为试材,研究化学药剂对红色砂梨着色调控的效应及相关生理机制。结果表明,在UV-B/白光诱导条件下,不同药剂处理对红色砂梨‘满天红’着色及主要果实品质的调控效应不同。0.4 mmol/L 脱落酸(abscisic acid,ABA)和3 mmol/L 赤霉素(gibberellic acid,GA)对‘满天红’果皮花青苷合成没有增效;2 mmol /L乙烯利(ethephon,ETH)、0.12 mmol/L 金雀异黄素(genistein,GNT)和2 mmol/L茉莉酸甲酯(methyl jasmonate,MJ)处理以及它们混合使用均能促进‘满天红’果皮花青苷合成,且ETH和MJ间存在显著的互作增益现象,这些处理还能较好地维持果实硬度、可溶性固形物、可溶性糖和有机酸的含量。本研究将为优质红色砂梨生产中的着色调控提供理论和技术支持。
关 键 词: 果树学;红色砂梨;花青苷;着色调控;化学药剂

Abstract: Red Chinese sand pears (Pyrus prifolia Nakai) are native to Yunnan province and southern part of Sichuan province. Recently, the pears had been widely accepted by consumers. Poor fruit coloration has been a noticeable problem, however, there is short of the technique of coloration regulation on production. Red Chinese sand pear cultivar, ‘Mantianhong’ (mid-maturing), was used as material in this study. Color response and related physiological mechanism of coloration regulation of red Chinese sand pears to postharvest induced influenced by chemicals were investigated systematically. The results are as follows: Different chemicals have different efficiency in coloration induced and fruit quality regulating. No positive efficiency was observed in 0.4 mmol/L abscisic acid (ABA) and 3 mmol/L gibberellic acid (GA) treatment in inducing anthocyanin accumulation of ‘Mantianhong’. However, 2 mmol/L ethephon (ETH), 0.12 mmol/L genistein (GNT), 2 mmol/L methyl jasmonate (MJ) alone and mixture of these chemicals enhanced anthocyanin accumulation in red Chinese sand pears. Simultaneous irradiation with MJ and ETH had a synergistic effect in inducing anthocyanin accumulation of ‘Mantianhong’. All these treatments can obtain fruit quality of ‘Mantianhong’ pear, such as fruit firmness, total soluble solids, soluble sugar and organic acid. This study will provide theoretical and technical support for improving the coloration of red Chinese sand pears.
