Abstract

The aim of this study was to determine the effectiveness of a Super absorbent polymer (SAP) containing copper (SAP-Cu) in controlling mal secco disease (MSD) of lemon caused by the fungus . Super absorbent polymer containing copper was characterized by atomic absorption spectrometry (AAS) and UV-VIS spectroscopy. tests were performed to determine the inhibitory effects of SAP-Cu against the pathogen on both potato-dextrose-agar medium and naturally infected lemon cuttings. Super absorbent polymer was able to absorb up to about 200 and 30 times its weight of ionized water and copper (II) sulfate solution (Cu ions at the concentration 236 mM), respectively. The distribution of copper released on twigs after 24 h of contact with SAP-Cu was determined by secondary ion mass spectrometry with time-of-flight analyzer (ToF-SIMS). Super absorbent polymer containing copper significantly inhibited the viability of in lemon twigs. Overall, the results of this study showed that the SAP could be a suitable carrier of antifungal compounds.

摘要

本研究的目的是确定含铜高吸水性聚合物（SAP-Cu）对由真菌引起的柠檬黑腐病（MSD）的防治效果。采用原子吸收光谱法（AAS）和紫外-可见光谱法对含铜高吸水性聚合物进行了表征。进行试验以确定SAP-Cu在马铃薯葡萄糖琼脂培养基和自然感染的柠檬插条上对病原菌的抑制作用。高吸水性聚合物分别能够吸收高达其重量约200倍的去离子水和30倍的硫酸铜溶液（浓度为236 mM的铜离子）。通过飞行时间二次离子质谱仪（ToF-SIMS）测定与SAP-Cu接触24小时后铜在嫩枝上的释放分布。含铜高吸水性聚合物显著抑制了柠檬嫩枝中病原菌的活力。总体而言，本研究结果表明，SAP可能是抗真菌化合物的合适载体。
