多孔淀粉固化杜香精油的制备及缓释性能研究

我国东北地区拥有丰富的杜香植物资源。该植物带有独特香气,带叶嫩枝含油量较高。然而,杜香精油挥发性强,稳定性差,香气不持久和携带不便等缺点限制了杜香精油及其相关产品的开发和利用。本文将主要探究了多孔淀粉固化杜香精油的制备工艺及其缓释性能。利用精油粉末化技术,采用研磨吸附的方法,制备了固化杜香精油粉末。利用DSC和TG探究了固化精油粉末的热学稳定性能并探究了其在不同温度下的缓释持香效果结果表明:多孔淀粉的最大吸油量为1.42 g·g^-1。多孔淀粉与杜香精油的质量比为1∶0.75(g·g^-1)时,固化精油粉末的气味较好,呈现出淡黄色粉末状态;固化精油粉末的保留率为杜香精油的3.57倍体现出其良好的热学稳定性;在同一温度下,相同时间内固化精油粉末比未固化精油的缓释持香效果更显著。多孔淀粉固化杜香精油的制备工艺简单,样品缓释持香效果明显,具有一定的应用推广价值。     

Chlamydospore formation of <Emphasis Type="Italic">Entoloma clypeatum</Emphasis> f. <Emphasis Type="Italic">hybridum </Emphasis>on mycorrhizas and rhizomorphs associated with <Emphasis Type="Italic">Rosa multiflora</Emphasis>

 Chlamydospores of Entoloma clypeatum f. hybridum were described on the mycorrhizas and rhizomorphs associated with Rosa multiflora. Their developmental pattern seems to be the Nyctalis type. This is the first report on chlamydospore formation on the mycorrhizae in entolomatoid fungi.

Thanks are due to Mr. D. Sakuma for allowing the specimens to be kept in Osaka Museum of Natural History. Correspondence to:H. Kobayashi     

Mycorrhizae of Entoloma saepium: parasitism or symbiosis?

The mycorrhizae of Entoloma saepium on Rosa sp. are comprehensively described and compared to other mycorrhizae of the genus Entoloma, as well as to similar unidentified mycorrhizae known from the literature. E. saepium appears to be more a parasite than a symbiont, as it invades and almost completely destroys the root meristem and young root cells.Considered as part IL of the series Studies on ectomycorrhizae; part XLVIII: Waller and Agerer (1993)     

离子注入加速棉花陆海杂种农艺性状遗传稳定性的研究

利用３０ＫｅＶ的Ｎ＾＋离子束注入陆地棉和海岛棉的花粉及杂交Ｆ１种子,分析了杂种后代农艺性状遗传稳定性的变化。结果表明：Ｎ＾＋离子辐照能显著地加速杂种后代的遗传稳定性,Ｆ４Ｍ４代性状稳定度可达９０％左右。Ｆ１种子辐照后代农艺性状多偏向陆地棉,而且花粉辐照杂交后代农艺性状表现出偏母遗传。同时以＾６０Ｃｏγ射线效应为对照,初步探讨了Ｎ＾＋离主入加速遗传稳定的机制。

本文报道了海南省粉褶蕈属[Entoloma(Fr.)Kumm.]6个新种,它们是:锈褐粉褶荤(Entoloma ferrugineobrunneum W.M.Zhang sp nov.),紫褐粉褶蕈(Entoloma purpureo-brunneum W.M.Zhang sp.nov.),丛生粉褶蕈(Entoloma caespitosum W.M.Zhangs sp.nov.)肉褐粉褶蕈(Entoloma carneobrunneum W.M.Zhang sp.nov.),近杯伞状粉褶蕈(Enloloma subclitocyboides W.M.Zhang sp.nov.),近偏生粉褶蕈(Entoloma subeccentricum W.M.Zhang sp.nov.),所有标本保藏于广东省微生物研究所真菌标本室。     

Taxonomy of Chrysotoxum festivum Linnaeus, 1758 (Diptera: Syrphidae) – an integrative approach

An integrative taxonomic approach revealed two taxa within Chrysotoxum festivum (Linnaeus, 1758) (Diptera, Syrphidae), C. festivum A and C. festivum B. In addition to morphological differences, results also showed significant distinction in geometric morphometrics of wings and surstyli, and in DNA sequence data (nuclear ITS2 sequences) between C. festivum A, C. festivum B, and the closely related species C. elegans Loew, 1841. From examination of type material, the name C. tomentosum Giglio‐Tos, 1890 is proposed for C. festivum B, and the taxon is redefined. © 2013 The Linnean Society of London
