以"巨峰"葡萄为试材,研究了果实生长发育期喷施天然矿物肥对葡萄果实品质和抗氧化酶活性的影响。结果表明:喷施天然矿物肥对"巨峰"葡萄果实品质有显著改良效果,果实硬度、果实着色、可溶性固形物分别比对照增加6.1%、30.2%、7.0%,而对单粒重、叶绿素含量影响不显著;喷施天然矿物肥还显著提高了"巨峰"葡萄叶片中愈创木酚过氧化物酶(G-POD)和抗坏血酸过氧化物酶(APX)活性;因此,生长发育期喷施天然矿物肥对改善"巨峰"葡萄果实品质有良好作用,可在"巨峰"葡萄商品化生产中合理应用。
‘Kyoho'grape was used as material for studying the effect of foliar spray of natural mineral fertilizer at growth stage on fruit quality and activities of antioxidant enzymes.The results showed that foliar spray of natural mineral fertilizer was effective on improving the fruit quality of‘Kyoho'.Fruit firmness,redness and soluble solid content were higher than those of control fruits,with the increase of 6.1%,30.2%,7.0%,respectively.Individual fruit weight and leaf chlorophyll content were not significantly affected by natural mineral fertilizer treatment.The enhanced activities of G-POD and APX in leaves of‘Kyoho'were also observed in natural mineral fertilizer treatment.In a word,foliar spray of natural mineral fertilizer at growth stage was helpful for improving‘Kyoho'fruit quality,which could be applied for commercial production of table grapes.
