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。

The present invention selects and uses hereditary hypertension rat and rat with normal blood pressure to make hybridization, and the rat whose blood pressure is normal and arterial pressure susceptivity reflection sensitivity is less than 0.3 ms/mm Hg can be screened out from filial generation, bred and propagated, and repeatedly bred and propagated, after above 12 generations so as to obtain the invented pure rat with stable hereditary property and spontaneous arterial pressure susceptivity reflection functional defect.

本发明涉及医学实验动物模型技术领域，是培育用于心血管疾病防治研究的一种自发性动脉压力感受性反射功能缺陷的纯种大鼠的方法。本发明选用遗传性高血压大鼠和正常血压大鼠杂交，从子代中筛选出血压正常、动脉压力感受性反射敏感性低于0.3ms/mmHg的大鼠培育繁殖，并反复按此标准在其下一代中筛选、繁殖，经12代以上便得到遗传性稳定的自发性动脉压力感受性反射功能缺陷纯种大鼠。

The trials were carried out in field experiment and artificial climate incubator. The sugar beet growth buds were treated at 1～3pairs of true leaves with gibberellin , autix , naphthaleneacetic acid and kinetin , and the plant growth regulating substances enhancing bolting of sugar beet in the first year and its doses were selected out. The sugar beet seedling induced by temperature and light were treated by abscisic acid , maleic hydrazide , uniconazole (S-3307) and paclobutrazol (PP333), and the plant growth regulating substances which make bolting reverse and their doses were screen out. The mechanisms of bolting and bolting reversing were discussed by examining the changes of endogenous hormones, activities of correlative enzyme to bolting, soluble protein, components of amino acid in the protein, components of fatty acid. The results were as follow
