摘要

研究了南方绿臭虫Nezara viridula L.取食对油菜种子萌发和种子化学品质(蛋白质、脂质、低聚糖、干物质和脂肪酸)的综合影响。受损的角质层产生异常苗和死种子的比例显著高于其他角质层。种子质量分析表明,受损种子的脂质和干物质含量较低,但粗蛋白质含量较高。由于臭虫的饲养,种子油中的脂肪酸谱发生了变化,油酸、硬脂酸和亚油酸的含量增加,亚麻酸的含量降低。在低聚糖方面,受损种子中果糖和水苏糖含量显著降低,而蔗糖含量较高。使用主成分分析的多变量分析提供了它们相互关系的结构化概述。因此,这些结果清楚地表明,尽管病毒乳杆菌不被认为是油菜的主要害虫,但它对油菜的取食活动导致了大量的种子损害和种子化学成分的有害改变。

The Impact of Nezara viridula L. (Heteroptera: Pentatomidae) Feeding on Canola Seed Germination and Chemical Quality.

This study investigates the comprehensive effects of the southern green stink bug, Nezara viridula L. feeding on canola seed germination and seed chemical quality (proteins, lipids, oligosaccharides, dry matter, and fatty acid profile). Damaged siliques originated significantly higher percentages of abnormal seedlings and dead seeds. Seed quality analyses demonstrated that damaged seeds showed lower levels of lipids and dry matter but higher levels of crude proteins. The fatty acid profile in seed oil was altered due to stink bug feeding, with increased levels of oleic, stearic, and linoleic acids and decreased levels of linolenic acid. Regarding oligosaccharides, the fructose and stachyose levels were notably lower in damaged seeds, whereas the sucrose level was higher. Multivariate analysis using principal components analysis provided a structured overview of their interrelationships. Therefore, these results clearly demonstrate that, although N. viridula is not considered a main pest of canola, its feeding activities on this plant results in substantial seed damage and detrimental alteration of seed chemical compounds.
