摘要:

针对设施葡萄生产中光温逆境导致果实品质欠佳(着色差)的问题,对2个葡萄园转色期的‘巨峰’和‘巨玫瑰’葡萄进行每日补光试验处理(4:00—5:00和19:00—22:00),观察处理前后果实品质的差异。结果表明,每日补光4 h处理后‘巨峰’和‘巨玫瑰’着色更深、更均匀,且补光处理能显著提高葡萄果实的颜色指数,补光处理后葡萄果皮的花色苷含量提高了5.00~19.42 µg/g;葡萄果实的可溶性固形物含量增加了0.5~1.7 °Brix,葡萄糖含量增加了0.42~3.43 mg/g,最终成熟期提早了5~7天。综合试验结果可知,在葡萄转色期进行补光处理,可以明显改善红色系葡萄的着色问题,提高葡萄品质,对优质葡萄生产有良好的应用价值。

Abstract:

Aiming at the poor fruit quality (poor coloring) caused by light and temperature adversity in the production of facility grape, ‘Kyoho’ and ‘Jumeigui’ were treated with daily supplementary lighting (4:00-5:00 and 19:00-22:00) in 2 vineyards during the veraison period. After daily supplementary lighting for 4 hours, the coloring of ‘Kyoho’ and ‘Jumeigui’ were deeper and more uniform. And the color index of red grape (CIRG) value of the grape fruits was increased under the supplementary lighting. After the treatment, the anthocyanin content of the grape peel increased by 5.00-19.42 μg/g; the soluble solid content of grape fruits increased by 0.5-1.7 °Brix; the glucose content increased by 0.42-3.43 mg/g. Then, the maturity period was 5-7 days earlier under the treatment. Above all, treating grapes with supplementary lighting in the veraison period could obviously improve the coloring and the quality of red grapes, and has good application value in the production of high-quality grapes.
