Pitchers plants of Nepenthes specie growing in infertile habitats have developed highly specialized apparatus for trapping and digesting arthropods to obtain suf- ficient growing nutrients. Nepenthes pitchers are generally recognized by several distinguishably morphological zones, and different districts exhibit distinct functions in prey capturing, combined effect of the several zones results in great trapping efficiency. This prey ability of Nepenthes pitchers potentially inspires an idea for biomimetic development of slippery trapping plate used in controlling agricultural pests, especially plague locust. In this paper, we reviewed the recent researches of Nepenthes pitchers, including surface structures, physical properties, and antiattachment functions. Apart from this, combined with our latest studies on mechanical controlling plague locust, the potential application of Nepenthes pitchers as establishing biomimetic models utilized in creating trapping plate was addressed, and several corresponding aspects requiring to be paid attention to in near future were also highlighted. 相似文献

以猪笼草的幼嫩茎段为外植体进行离体组织培养及植株再生,研究结果表明:以液体培养基1/2MS+6-BA1.0mg/I.+NAA0.1mg/L对芽的初始诱导以及固体培养基1/2MS+6-BA2.0mg/L+NAA0.1mg/L对不定芽的增殖效果最好,增殖率达419%;生根培养基以1/4MS+IBA0.5mg/L+活性碳(0.01%)为最佳,生根率可达100%. 相似文献

一只蚂蚁匆匆忙忙地沿着一枚叶片爬行,不时停下脚步四下张望,然后似乎发现了什么,又急匆匆地继续赶路。来到一个巨大“瓶子”的顶部时,这只长途跋涉的蚂蚁终于停下脚步,开始贪婪地吃起来,原来这个“瓶子”的瓶口处布满了香甜的蜜汁。然而,就在饱餐后的蚂蚁打算踏上归途时,突然脚下一滑,掉进瓶底,再也没能爬上来。这顿甜蜜的大餐竟成了蚂... 相似文献

来美国之前,我就了解到这片新大陆上有很多特有的食虫植物,其中与主要分布于亚洲热带地区的猪笼草最相似的要算是瓶子草科的成员。我对瓶子草向往已久,这次随系里参观了位于密歇根州下半岛(密歇根州由滨湖的东西向的上半岛和南北向的下半岛组成)北部的密歇根大学生物站,并走进一片温带沼泽,终于目睹了紫瓶子草和两种茅膏菜的风采。 相似文献

Pitchers of the carnivorous plant Nepenthes have evolved specialized organs serving the purpose of attracting,capturing,retaining and digesting small animals,mostly insects.They consist of several well distinguishable zones,including a leaf-like lid,a collar-like peristome,a slippery zone and a digestive zone,differing in morphology,microstructure,chemical composition and physical properties.Discriminating zones display different functions,and the combined effects of several zones result in great trapping efficiency.The principal aim of this review is to introduce the structure and physiochemical properties of the pitcher surface,as well as the interaction between the pitcher surface and the insect attachment systems.Combining with our present study,the potential application of the pitcher surface being utilized in bionics to manufacture insect slippery trapping plates is discussed,and the original research direction of the pitcher surface and its application on agricultural pest control is highlighted. 相似文献

猪笼草叶笼能够捕集昆虫并将其消化成生长所需的营养元素,依据宏/微观形貌结构差异可划分为盖子、口缘、滑移区与消化区等区域。口缘密布楔形盲孔的辐射状沟脊结构可使液膜产生定向移动,滑移区形貌结构呈现抑制昆虫附着、低黏附超疏水等特性,受到学者普遍关注并逐步成为研究热点。从口缘与滑移区在工程仿生领域的研究现状入手,介绍其形貌结构特征与功能特性,重点关注以其为仿生原型制备液膜定向传输、昆虫滑移捕集、超疏水等功能表面的研究进展,并对未来需要关注的研究内容进行分析,从而进一步加深人们对叶笼形貌结构与功能特性的认识,为功能表面仿生研制提供新思路。 相似文献
