The main results are shown as follows:1.Screening freezing tolerant cultivars and lines of chrysanthemumTwenty seven lines of chrysanthemum grown outdoors were screened using \'injury rate\' and \'injury index\'.There were 7 cultivars and lines,which were relatively high tolerant to freezing treatment,i.e.,\'Jinbuhuan\',\'Xuetao\',\'Fuli\',\'Donglin 4\',\'Donglin 6\',\'Donglin 9\', and \'Donglin 13\'.There were 3 cultivars and lines,which were less tolerant,i.e.,\'Fenmeigui\', \'Donglin 1\',and \'Donglin 2\';The determination of electrolyte leakage,and contents of free proline,MDA,CAT,fructose,glucose and soluble sugars on 7 lines of chrysanthemums at different stages freezing showed that \'Xuetao\' and \'Donglin 4\' were more tolerant than others, and that especially \'Donglin 4\' was able to regulate its osmotic pathway to alleviate the \'injury degree\' caused by freezing conditions.2.Protein expression profile of chrysanthemum under low temperature stressTwo-dimensional liquid chromatography was applied to fractionate and analyze total protein taken from \'Donglin 4\' leaves grown at low temperature and at normal condition. Chromatography peaks of fraction were transformed to gel graph by ProteoVue software.

主要研究结果如下：1、露地菊抗冻品种和品系的筛选利用受伤率和伤害指数两项指标对27个露地菊品系进行耐低温筛选，筛选出'金不换\'、'雪涛\'、'富丽\'、'东林4号\'、'东林6号\'、'东林9号\'、'东林13号\'等7个耐低温品系，同时发现'粉玫瑰\'、'东林1号\'、'东林2号\'三个品系的耐低温能力最差；通过对不同自然低温处理时期，7个品系的电导率、丙二醛含量、脯氨酸含量、过氧化氢酶、果糖、葡萄糖和可溶性糖等指标的测定发现，'雪涛\'和'东林4号\'的耐低温能力要强于其它品系，尤其是'东林4号\'对低温的调节能力较强，在低温胁迫下，能够调节渗透途径减轻低温的伤害。2、低温胁迫下，露地菊蛋白质表达谱分析利用二维液相色谱技术，分离了'东林4号\'露地菊品系的低温处理和对照样品的总蛋白，通过ProteoVue软件分析发现：处理样品与对照相比共有蛋白差异点36个，其中显著增强表达的蛋白差异点有26个。

That there was some awareness of a change in musical techniques and outlook in the years around 1320 is suggested also by the earliest music to exemplify the notation described in Philippe de Vitry's treatise, the motets for the roman de Fauvel copied into manuscript F-Pn fr ,146 in 1316, some of them extensive works several times longer than the motets of the previous generation and displaying a range of notational values far greater than it was possible to notate with the previous Franconian and post-Franconian techniques.
