摘要

通过公私合作研究了壳聚糖控制葡萄树干病害(GTDs)的潜力。为了了解壳聚糖的作用模式,进行了体外试验、葡萄园药效试验和实验室分析。在体外试验中,可溶性最强的低分子量壳聚糖通常最有效。在葡萄园中,最有效的是中等分子量的壳聚糖,特别是能形成保护膜的壳聚糖盐酸盐。它们可用于修剪、重新修枝或刮除造成的伤口。

Chitosans and grapevine trunk diseases: surprising results from laboratory and vineyard studies
The potential of chitosans to control grapevine trunk diseases (GTDs) has been studied in a public-private partnership. In vitro tests, vineyard efficacy trials and laboratory analyses were carried out to understand their mode of action. In vitro, low molecular weight (MW) chitosans, the most soluble, were often the most effective. In the vineyard, the most effective were those with a medium MW, in particular chitosan hydrochlorides which form a protective film. They could be used to dress wounds caused by pruning, re-trunking or curettage.
