8个水稻品种的条纹叶枯病抗性特征 总被引:27,自引:6,他引:27
利用强迫饲毒、集团接种、非嗜性测验、抗生性测验的方法研究与分析了8个抗条纹叶枯病水稻品种对条纹病毒和介体灰飞虱的抗性,发现不同水稻抗性品种的抗性特征并不完全相同。IR36、Kasalath、窄叶青8号、道人桥、DV85既抗条纹病毒又抗介体灰飞虱,对条纹叶枯病所表现的抗性是条纹病毒和介体灰飞虱抗性共同作用的结果; 爱知97和Kenta Nakan抗条纹病毒,但不抗介体灰飞虱,对条纹叶枯病所表现的抗性是品种对条纹病毒的抗性;而IR24对条纹病毒和介体灰飞虱仅表现中等抗性。 相似文献

Rice Metabolomics 总被引:1,自引:0,他引:1
Metabolomics is a recently developed technology for comprehensive analysis of metabolites in organisms. Plant metabolites that are produced for the growth, development, and chemical defense of plants against climatic alterations or natural predators are also useful to us as nutrients or medicines; hence, it is important to comprehend the amounts and varieties of plant metabolites. Besides providing an understanding of the metabolic state in plants under various circumstances, metabolomic techniques are applicable to the clarification of the functions of unknown genes by using natural variants or mutants of the target plants. Furthermore, a metabolomic approach might be useful in the breeding of crops, since valuable plant traits such as taste and yield are closely related to metabolic conditions. Here, we describe the methodology of metabolomics including sample extraction and preparation, metabolite detection, and data processing and analysis, and introduce the application of metabolomic studies to rice. 相似文献

安徽省水稻品种(系)对稻瘟病和稻曲病的抗性评价 总被引:4,自引:0,他引:4
2013年对安徽省103份水稻品种(系)进行稻瘟病和稻曲病田间抗病性鉴定。结果表明,参试材料对稻瘟病表现抗病和中抗的分别有5份和9份,占13.59%;表现中感的有25份,占24.27%;表现感病和高感的分别有33份和31份,占62.14%。对稻曲病表现抗病和中抗的分别有6份和7份,占12.62%;中感的有55份,占53.40%;感病和高感的分别有29份和6份,占33.98%。对两种病害均能达到抗病或中抗的只有3份,分别是G优6号、Y两优1500和协优118。 相似文献

饲料用稻谷和糙米的营养特性 总被引:6,自引:0,他引:6
对18个饲料用水稻样品的稻谷和糙米的常规营养成分、氨基酸组成和有效能值进行了分析和测定。稻谷和糙米含蛋白质分别为(8.85±1.23)%, (10.35±1.33)%,含总能分别为(15.83±0.28) MJ/kg, (15.95±0.20) MJ/kg, 含消化能10.28 MJ/kg 和 13.48 MJ/kg。稻谷的养分消化率明显低于糙米的相应值。主要是由于稻谷含粗纤维8.94%,而糙米的相应值为1.19%。稻谷和糙米分别含赖氨酸0.29%和0.44%,蛋氨酸0.10%和0.18%,苏氨酸0.26%和0.30%。用作猪饲料时,赖氨酸是第一限制性氨基酸,苏氨酸是第二限制性氨基酸,异亮氨酸是第三限制性氨基酸。 相似文献
