知道吗？树也是可以走路的

环球人文地理 2022年第3期 104-105页

作者：鸣鸟不飞 alexey Yakovlev Todd Petit Gordon K A Dickson

在经典韩剧《蓝色生死恋》中，恩熙曾对哥哥俊熙说：“下辈子我想做一棵树，这样就能一直留在一个地方，不会离开。”从古至今，树木始终是以“扎根大地”的形象出现，几十年乃至千年的岁月蹉跎中，它们都静守一方，与土地做伴。俗话说...

在经典韩剧《蓝色生死恋》中，恩熙曾对哥哥俊熙说：“下辈子我想做一棵树，这样就能一直留在一个地方，不会离开。”从古至今，树木始终是以“扎根大地”的形象出现，几十年乃至千年的岁月蹉跎中，它们都静守一方，与土地做伴。俗话说“人挪活，树挪死”，因为树木一旦被移动，就会伤及根本，很难活下来。自然界的规律让大多数树木只能扎根土地，长期固定于一地，依靠汲取土壤中的营养而存活。然而，在现实生活中，却真实存在着一种非常神奇的树木，

Romanov Emmanuel Institute of Biochemical Physics Russian Academy of Sciences Moscow Russia imiryazev Institute of Plant Physi- ology Russian Academy of Sciences Moscow Russia Timiryazev Institute of Plant Physi- ology Russian Academy of Sciences Moscow Russia Timiryazev Institute of Plant Physi- ology Russian Academy of Sciences Moscow Russia Laboratory of Plant Physiology Wageningen University Wageningen The Netherlands.

Wild-type potato (Solanum tuberosum L.) plants and their transformants harboring agrobacterial rolB or rolC genes under control of the patatin class I promoter were cultured in vitro. These plants were used as a source of single-node stem cuttings. The structure of native starch in tubers formed on cuttings was determined using methods of X-ray scattering and differential scanning microcalorimetry (DSC). It was found that in starch from tubers of rolB plants the melting temperature of crystalline lamella was lower and their thickness was less than that in wild-type potato. In tubers of rolC plants starch differed from starch in wild-type plants by a higher melting temperature, reduced melting enthalpy, and a greater thickness of crystalline lamellae. The melting of starch from tubers of rolC plants proceeded as the melting of two independent crystalline structures with melting temperatures of 338.0°K and 342.8°K. Overall data show that starches of different structure can be obtained by using transgenic approach.

腐植酸包膜尿素减少土壤氮素损失的研究

腐植酸 2024年第5期 50-58页

通过室内模型试验,以普通尿素(U)、腐植酸包膜尿素(U-HA)和脲酶抑制剂N-(正丁基)硫磷三酰胺处理尿素(U-UI)为研究对象,研究了3种尿素肥料对土壤氮素转化过程的影响。更正研究了尿素肥料对土壤化学(水浸提N-NH4和N-NO3含量)和微生物特性(N2O实际和潜在排放速率、基础呼吸和底物诱导的呼吸、微生物生物量碳、乙烯排放速率)的影响,旨在验证:(i)腐植酸包膜尿素是否具有减少土壤氮素损失的能力;(ii)与合成脲酶抑制剂相比,它是如何影响土壤生物活性的。结果表明,U-HA在减少土壤氮素损失方面具有与U相当的优势,使土壤N-NH4含量增加了35%,硝酸盐含量减少了9%,N2O排放减少了50%。U-HA使土壤基础呼吸提高了10%,土壤微生物群落比活性提高了7%,提供了最高的代谢熵qCO_(2)。与U-UI相比,U-HA主要表现为介于U-UI和U之间的效果。考虑到腐植酸原料成本低,U-HA可以被认为是减少土壤氮素损失的有前景的工具。

在全球不断变暖的大环境下,中国冻土区受气候影响而产生的各类结构性变化已经对人类生活产生相应的负面影响,而位于俄罗斯西伯利亚地区的萨哈(雅库特)共和国面临同样的问题,热喀斯特湖的发育对研究区内的领土开发、农耕地开垦、畜牧业等均已产生破坏性影响。借鉴俄罗斯对冻土的丰富研究,为我国相关研究提供思路。通过梳理相关资料,总结出雅库特地区具有强大陆性气候,冬季寒冷漫长,年际温差大等气候特征。该地冻土区主要由于年气温上升,活跃层厚度增加,导致土壤下陷,最终形成热喀斯特湖地貌(又称阿拉斯)。该地区有发育缓慢,无序分布,受地质结构影响较大以及分布地区广等发育特点。

20世纪的俄语经典文学在当下俄国依然遭遇着十分意识形态化的解读,本文作者认为,无论是土壤派批评还是自由派批评,在对苏维埃经典做出评价时往往都带有政治意图,本文以当下俄国批评对普里什文、格林、阿·托尔斯泰、布尔加科夫和普拉东诺夫五位作家两种截然不同的接受为例,说明"20世纪上半期的俄国经典文学离我们越远,就变得越是意识形态化,越能引起纷争","20世纪上半期的俄国经典文学正在成为政治斗争中一枚可以兑换的硬币"。作者主张,对于经典作家及其作品的真正合理的解读方式还是返回文本,返回特定的历史语境。
