Broad and high resistance genes against brown planthopper derived from resource "2183" of Guangxi common wild rice, Oryza rufipogon Griff were tagged and mapped in this study. Genetic homozygous resistance material,"2183 "was obtained by anther culture technique and used to cross with TN1, a susceptible rice variety.

本研究选用对稻褐飞虱具有广谱高抗性的普通野生稻资源"2183"为试验材料，通过花药培养获得抗性纯合体，与感虫性材料TN1杂交和测交，获得TC_1F_2作图群体，用稻褐飞虱生物型2对群体进行抗性鉴定。

Analysis of the protein sequence suggest that HoSEPl is most similar to Arabidopsis AGL6 with 64% identity, and by highest identity to two unknown genes, pAOM3 of Asparagus and an OsMADS of Oryza (respectively 90%, 70%) among monocotyledon plants.

蛋白序列分析表明，HoSEP1与拟南芥AGL6蛋白同源性最高(64%)，与单子叶植物同源性最高为石刁柏的pAOM3和水稻的OsMADS，分别为90%和70%。

S extract had an inhibition effect against Sphaerotheca fuligenea,The inhibition rate was 100% when extract concentration was 20mg/mL and the inhibition rate got to 67.66% even at the concentration of 2.5mg/mL. The extract of E. humifusa had different preventive effects against four strains of S. fuliginea from four districts in Shanghai. The preventive effects on the Qibao and Baoshan were better than those of Nanhui and Qingpu. The microorganism inhibition experiment by filter papers indicated that the extract of E. humifusa had higher inhibition effect against bacteria than on pathogenic fungus. Diameters of the zone of inhibition of salmonellas, Echerichia coli and Staphylococcus aureus were 15.77mm, 12.27mm and 10.53mm respectively. The extract of E. humifusa had a certain effect against Colletotrichum lagenarium, Botrytis cinerea, Rhizoctomia solan and Pyricularia oryza but no effect against Helminthosporium maydis and Gibberella zea. The 4 cation exchange resins and ethanol deposition were used to isolate the active fractions from supernate after alkali deposition.

提取液对黄瓜白粉病菌体外分生孢子萌发抑制实验表明地锦提取液对黄瓜白粉病菌分生孢子的萌发有很好的抑制作用，抑制率随着地锦提取液浓度的增大而增高，当浓度为20mg/mL时，抑制率达到100%，即使在浓度为2.5mg/mL时，抑制率也达到了67.66%；室内盆栽苗期预防性实验表明了地锦提取液对上海4个不同地区的黄瓜白粉病菌均具有不同程度的抑制效果，对七宝和宝山地区的菌株抑制效果优于南汇和青浦地区的菌株；用滤纸片法测定了地锦提取液的抑菌谱，实验结果表明地锦提取液对供试的4种植物病原真菌：黄瓜炭疽病菌、黄瓜灰霉病菌、水稻纹枯病菌和水稻稻瘟病菌均具有一定的抑制效果，而对玉米小斑病菌和小麦赤霉病菌没有抑制效果，对供试的3种人类致病细菌沙门氏菌、大肠杆菌和金黄色葡萄球菌均具有很好抑菌效果，抑菌圈直径分别为：15.77mm， 12.27mm和10.53mm。

Based on plant morphological traits, some types of strategies could be divided. The regeneration strategies of three species, Eriocaulon buergerianum, Juncus articulatus and Sagittaria potamogetifolia, had characteristics of r-strategists, and Oryza rufipogon, Scirpus triangulatus and Eleocharis plantagineiformis had characteristics of K-strategists.

根据植物的功能形态学特征，可以分出一些生活史对策类型，如从种子特征来看，谷精草、小花灯心草和小慈姑等植物的更新对策具有明显的r-对策特点，粉被苔草、野荸荠和普通野生稻等具有一定的K-对策特点；依据成株特征也可以区分出竞争、躲避或耐压对策的定居对策类型。
