Investigation of Garden Nurseries in Linzhi City of Tibet

Garden nurseries in Linzhi City, Tibet were comprehensively investigated, 132 garden plant species were covered. The investigation showed that garden nurseries in the local area remained in the initial development stage, and the scale of most nurseries was small, and there was blank in many aspects of the landscape architecture industry.

Landscape Pattern Optimization of Chengdu Based on Modern Garden City

TOptimization of regional landscape pattern is significant for improving function and value of ecosystem,and restraining the expansion of urban layout.Taking Chengdu City for example,this paper applied RS and GIS techniques,landscape indexes and ecological service function evaluation to further analyze the temporal and spatial characteristics of landscape pattern and spatial differences of regional ecological functions,and on this basis,identified the spatial distribution of ecological source lands.Based on the long-term objective of building Chengdu into a modem garden city,this paper applied the accumulative cost distance model and introduced garden city theory to construct regional ecological corridors and ecological nodes,and explored the approaches of optimizing landscape pattern of modem garden city.The results showed that a great deal of arable land has been transferred to construction land in the urbanization;intensity of regional ecological functions showed obvious spatial differences;ecological source lands were mainly distributed in the Longmen Mountain,the Qionglai Mountain,the Changqiu Mountain and the Longquan Mountain;according to actual conditions of the study area,the road ecological corridors,river corridors and agricultural corridors in the layout of "four rings and six radial corridors" were constructed;ecological nodes dominated by intersection,wetland and forest park were formed.This research method and results are significant references for building Chengdu into a modem garden city     

白花虎眼万年青QtJMT基因的克隆及其植物表达载体的构建

茉莉酸及其甲基化的衍生产物茉莉酸甲酯,后者具有较高生物活性,在植物的生命活动过程中发挥重要作用。茉莉酸甲基转移酶(jasmonic acid carboxyl methyltransferase, JMT)作为甲基转移酶类家族中的重要成员,是将茉莉酸甲基化衍生为茉莉酸甲酯过程中发挥催化作用的关键酶,过表达能够使得植物内源茉莉酸甲酯的生物合成能力增强,内源茉莉酸甲酯的含量提高,进而增强植物抗逆性及提高植物次生代谢物质含量,以及调控植物生长发育。白花虎眼万年青具有抗逆性强、次生代谢物质丰富、以及器官再生方式独特等特点,可能具有较高生物活性的茉莉酸甲基转移酶及其分子机制,但是尚未见到报道。本研究根据白花虎眼万年青叶上珠芽转录组分析数据,设计引物,克隆分离出茉莉酸甲基转移酶基因完整编码区,进而对其进行了三维立体结构、蛋白质保守序列及系统发育等生物信息学分析,将其命名为QtJMT基因,并成功将其连接到泛素启动子(pUB)驱动的植物表达载体上。本研究结果为QtJMT基因的深入分析其功能及在花卉分子育种中的应用提供了一定的依据。

The Grand Sight Garden in Chinese traditional novel "The Story of the Stone" takes an important position in Chinese traditional landscape architecture.In this paper,the aesthetic value of the Grand Sight Garden is analyzed and the real meaning and practical value of this fictitious "garden" is discussed from two aspects: composition structure and artistic conception.     

Production and characterization of interspecific hybrids between Asparagus kiusianus Makino and A. officinalis L.

Interspecific hybridization is a useful technique to introduce characteristics from wild species into crops. Garden asparagus (Asparagus officinalis, 2n = 2x = 20) is an economically important vegetable that is native to the Mediterranean region but widely cultivated in many countries. The genus Asparagus is comprised of over 100 species. Asparagus kiusianus (2n = 2x = 20) is a wild asparagus species endemic to Japan. This species occurs on the coast and is likely to be a salt-resistant species. Although the geographic distribution of these two species is not close, molecular phylogenetic analysis demonstrated that these two species are closely related. In this study, a reciprocal cross between A. officinalis and A. kiusianus was carried out by hand pollination, and progeny were obtained from both crossings. These progeny exhibited a morphologically intermediate phenotype in terms of flower shape, and restriction fragment length polymorphism analysis confirmed that these were indeed interspecific hybrids. The interspecific hybrids were fertile, and backcross progeny with garden asparagus was also generated. These interspecific hybrids are expected to supply novel traits to garden asparagus.     

Comparative Study on the Development of Tibetan Traditional Lingka and Han Garden

Tibetan traditional garden(Lingka) represented by the Norbuglingka is an important component of the Chinese traditional garden system. It is worth the attention from the academic fi eld because of the garden style with regional features and outstanding national and religious cultures. By researching the development history of Tibetan traditional Lingka and Han Garden and comparing the differences between their development stages and styles, it was found that both of them originated from the love and hankering for nature, but they presented different forms and characters because of different religious beliefs, natural ecological views, activities in garden, garden cultures, and so on. For the communication between Tibet and the Central Plain, Tibetan Lingka and Han garden have infl uenced and benefi ted each other, and fi nally shown the current patterns.     

Application of Classical Garden Design in Landscaping of West Sichuan Plain
