摘要

植物病原菌在世界范围内对农作物造成严重危害。目前疾病管理是由合成化学品完成的。在本报告中，肉桂tamala (Buch.-Ham.)T. Nees & Eberm。通过气相色谱- fid和GC/MS分析，发现(E)-肉桂醛(40.6%)、(E)-肉桂乙酸酯(19.6%)、芳樟醇(10.2%)和苯甲醛(3.6%)为标记成分。采用接触法、挥发法和孢子萌发抑制法测定了柽柳肉桂(Cinnamomum tamala, buchh .- ham)的抑菌活性。t.n Eberm。对茄枯丝核菌ag4、葫芦小蠹蛾和澳大利亚双北极星的抑制作用。在500ppm ~ 560ppm的浓度范围内，塔玛拉油对毒食法真菌生长有完全抑制作用。滴滴扩散法固相微萃取分析发现，苯甲醛存在于培养皿顶空气中，是对所测植物病原菌最有效的抗真菌化合物之一。同样，500 ppm的油浓度会抑制孢子的萌发。因此，含有此类组合物的产品可用于植物病害管理。

Inhibitory effect of cinnamon ( Cinnamomum tamala (Buch.-Ham.) T.Nees & Eberm.) essential oil and its aldehyde constituents on growth and spore germination of phytopathogenic fungi

Plant pathogens lead to severe damage of the agricultural crops, worldwide. The disease management is currently being done by the synthetic chemicals. In the present report, Cinnamomum tamala (Buch.-Ham.) T. Nees & Eberm. oil was analyzed by gas chromatography-FID and GC/MS, which revealed (E)-cinnamaldehyde (40.6%), (E)-cinnamyl acetate (19.6%), linalool (10.2%) and benzaldehyde (3.6%) as marker constituents. Contact, volatile and spore germination inhibition assays were performed to determine the antifungal activities of Cinnamomum tamala (Buch.-Ham.) T.Nees & Eberm. against Rhizoctonia solani AG 4, Choanephora cucurbitarum and Bipolaris australiensis. C. tamala oil 500-560 ppm showed complete fungal growth inhibition in poison food technique over concentration range of. Solid-phase microextraction analysis of drop diffusion assay revealed the presence of benzaldehyde in headspace of Petri-plate, and found to be one of the strongest antifungal compounds against tested phytopathogens. Similarly, an oil concentration of 500 ppm inhibits spore germination. Therefore, products containing such compositions can be used for the plant diseases management.

期刊介绍： Town Planning Review has been one of the world"s leading journals of urban and regional planning since its foundation in 1910. With an extensive international readership, TPR is a well established urban and regional planning journal, providing a principal forum for communication between researchers and students, policy analysts and practitioners. To mark TPR’s centenary in 2010, it is proposed to publish a series of ‘Centenary Papers’ -- review papers that record and reflect on the state of the art in a range of topics in the general field of town and regional planning.
