Abstract

Phytophthora citrophthora exerts detrimental effects on strawberry growth and physiology. In the presence of P. citrophthora, strawberry plants may face mineral deficiency during their growth. This study aimed to investigate the impact of P. citrophthora on ‘Albion’ strawberry plants under conditions of calcium (Ca), iron (Fe), and zinc (Zn) deficiency. Plants of ‘Albion’ strawberry cultivar (2 months old) were used as an experimental material. After 2 months of growth in a nutrient solution, these plants were subjected to 2 months of deficiency in Ca, Fe, or Zn. Following this period, P. citrophthora infection was introduced to the strawberries over a 3-week time frame. The findings of this research indicated that the most severe disease symptoms were observed under Fe deficiency conditions. Furthermore, when P. citrophthora infection coincided with Fe deficiency, there was a notable decrease in leaf-relative water content, accompanied by slight wilting symptoms. Overall, P. citrophthora infection led to an increase in the concentrations of chlorophyll precursors, including Proto IX, Mg-Proto IX, and Pchlide. Both nutrient deficiency conditions and P. citrophthora infection contributed to a decrease in cortical cell expansion. In addition, under nutrient deficiencies, the diameter of xylem conduits generally increased in both infected and non-infected plants, except in cases of P. citrophthora infection combined with Fe deficiency. Notably, the severity of P. citrophthora wilt was found to be higher under Fe deficiency conditions.

缺钙、缺铁和缺锌时疫霉菌对草莓生理和组织学的影响
柠檬疫霉菌(Phytophthora citrophthora)对草莓的生长和生理产生不利影响。在 P. citrophthora 的存在下,草莓植株在生长过程中可能会面临矿物质缺乏的问题。本研究旨在调查在缺钙(Ca)、缺铁(Fe)和缺锌(Zn)的条件下,P. citrophthora 对'Albion'草莓植株的影响。实验材料为 "Albion "草莓栽培品种的植株(2 个月大)。这些植株在营养液中生长 2 个月后,又经历了 2 个月的钙、铁或锌缺乏。在这之后的 3 周时间内,草莓会受到 P. citrophthora 的感染。研究结果表明,在缺铁条件下观察到的病害症状最为严重。此外,当 P. citrophthora 感染与缺铁同时发生时,叶片相对含水量明显下降,并伴有轻微的萎蔫症状。总体而言,P. citrophthora 感染导致叶绿素前体(包括 Proto IX、Mg-Proto IX 和 Pchlide)浓度增加。养分缺乏条件和 P. citrophthora 感染都会导致皮层细胞膨胀减少。此外,在养分缺乏的条件下,感染和未感染的植株木质部导管的直径都普遍增大,但 P. citrophthora 感染和铁缺乏的情况除外。值得注意的是,在缺铁条件下,P. citrophthora 枯萎病的严重程度更高。

期刊介绍: Erwerbs-Obstbau ist als internationales Fachorgan die führende Zeitschrift für Wissenschaftler, Berater und Praktiker im Erwerbsobstbau. Neben den wirtschaftlich führenden Obstarten widmet sich die Zeitschrift auch den Wildobstarten bzw. neuen Obstarten und deren zukünftige Bedeutung für die Ernährung des Menschen. Originalarbeiten mit zahlreichen Abbildungen, Übersichten und Tabellen stellen anwendungsbezogen den neuesten Kenntnisstand dar und schlagen eine Brücke zwischen Wissenschaft und Praxis. Die nach einem Begutachtungsprozeß zur Publikation angenommenen Originalarbeiten erscheinen in deutscher und englischer Sprache mit deutschem und englischem Titel. Review-Artikel, Buchbesprechungen und aktuelle Fachinformationen runden das Angebot ab.
