前言化学交联结构对弹性体材料力学性能的影响,经长期的研究,有大量的报告。对交联结沟与拉伸强度的相互关系,出现了截然相反的观点。在硫黄促进剂体系中,伴随着硫化反应,有大量的复杂反应,生成各类型的单硫醚、双硫醚和多硫醚交联的主链异构结构。这些复杂的反应及随之生成的网络结构取决于硫化体系及其硫化条件。阐明硫化胶中真正的交联结构是极其重要的。

In Vitro Screening of Endophytic Trichoderma sp. Isolated from Oil Palm in FGV Plantation against Ganoderma boninense

引用

Advances in microbiology 2022年第7期12卷 443-457页

作者： Elya masya mohd Fishal Ili Bazilah Abd Razak Nor Hidayah Bohari muhammad Ashraf Arif mohd nasir Crop Protection and Biosolution Department FGV R & D Sdn Bhd Bandar Enstek Malaysia

The potential of several endophytic Trichoderma isolates, isolated from healthy oil palm roots was assessed against Ganoderma boninense (PER71), the causal agent of Basal Stem Rot (BSR) disease through in vitro screening. In the dual culture assay, all endophytic Trichoderma isolates were found to be capable of inhibiting the growth of PER71 mycelium, by causing more than 70% inhibition of the pathogen’s radial growth (PIRG). Trichoderma asperellum m103 has caused the highest inhibition at 93.14%. The volatile compound produced by m103 also suppressed 65% of the pathogen’s radial growth. On the other hand, T. harzianum, m108 was found to have the ability to produce non-volatile compounds that is toxic and it has effectively inhibited 98.18% of the growth of PER71. Collectively, T. asperellum m103 and T. harzianum m108 have the potential to inhibit the growth of G. boninense PER71. These isolates were shown to be viable options for the future management of G. boninense in the oil palm field.

植物入侵会造成入侵地生态系统功能和稳定性的破坏。与原产地种源相比,入侵种源植物在生理学特性方面有所不同,使其在资源利用和抵抗环境胁迫具有较强的竞争优势。叶绿素荧光特性与植物光合作用效率密切相关,对植物生长具有重要作用。氮沉降加剧是全球变化的一个重要因子,土壤微生物对植物吸收利用土壤养分至关重要。通过施用细菌抑制剂(链霉素)和真菌抑制剂(扑海因)选择性抑制的土壤微生物活性,开展乌桕盆栽实验,在模拟氮沉降背景下,研究不同微生物群落如何影响入侵乌桕叶绿素荧光特性,有助于理解入侵植物的进化特征和入侵机制,为有效防控入侵植物并降低其对生态系统危害提供理论依据。以原产地地和入侵地两个种源乌桕(Triadica sebifera)为研究对象,在氮沉降条件下,通过调控土壤细菌和真菌,探讨两个种源乌桕叶绿素荧光参数差异。结果显示:氮沉降显著增加乌桕相对叶绿素含量(SPAD)、光系统II的最大量子产率(F_(v)/F_(m))、非光化学猝灭(NPQ)和半饱和光强(I_(k))。入侵种源乌桕比原产地具有较低SPAD。氮沉降与细菌抑制剂共同作用显著增强了F_(v)/F_(m)、NPQ和I_(k),显著减弱了光能利用率(α)和SPAD。细菌抑制剂减缓了本地种源乌桕α,真菌抑制剂促进本地种源乌桕I_(k),抑制入侵种源乌桕I_(k),细菌和真菌抑制剂可显著降低原产地乌桕α。氮沉降与生物抑制剂可显著作用于乌桕叶片SPAD。氮沉降、土壤微生物和不同乌桕种源可共同作用于光系统Ⅱ实际光合量子产率Y(Ⅱ),α和潜在最大相对电子传递速率(ETR_(max))。因此,氮沉降与生物抑制剂对乌桕叶绿素荧光特性具有协同作用,入侵种源乌桕对土壤微生物控制的响应不明显,在微生物控制条件下依然具有较强的适应能力,因而具有较强的入侵能力。
