| 1 | 水稻耐冷胁迫的研究进展显示文摘水稻冷胁迫是一个长期威胁着包括中国在内的许多国家的粮食安全的重要问题。本文概述了水稻冷胁迫的危害性、水稻在冷胁迫下产生的生理变化、水稻耐冷胁迫的程度的鉴定方法、水稻上一些耐冷胁迫的遗传机理等方面的内容,并对未来耐冷胁迫研究领域的方向及策略作了展望。 | 饶玉春 杨窑龙 黄李超 潘建伟 马伯军 钱前 曾大力 | 2013 | 分子植物育种2013，11，3： | 22 |
| 2 | Effects of rice or wheat residue retention on the quality of milled japonica rice in a rice–wheat rotation system in China显示文摘In rice–wheat rotation systems, crop straw is usually retained in the field at land preparation in every, or every other, season. We conducted a 3-year-6-season experiment in the middle–lower Yangtze River Valley to compare the grain qualities of rice under straw retained after single or double seasons per year. Four treatments were designed as: both wheat and rice straw retained(WR), only rice straw retained(R), only wheat straw retained(W), and no straw retained(CK). The varieties were Yangmai 16 wheat and Wuyunjing 23 japonica rice. The results showed contrasting effects of W and R on rice quality. Amylopectin content, peak viscosity, cool viscosity, and breakdown viscosity of rice grain were significantly increased in W compared to the CK, whereas gelatinization temperature,setback viscosity, and protein content significantly decreased. In addition, the effect of WR on rice grain quality was similar to that of W, although soil fertility was enhanced in WR due to straw being retained in two cycles. The differences in protein and starch contents among the treatments might result from soil nitrogen supply. These results indicate that wheat straw retained in the field is more important for high rice quality than rice straw return, and straw from both seasons is recommended for positive effects on soil fertility. | Pengfu Hou Yanfeng Ding Guofa Zhang Quan Li Shaohua Wang She Tang Zhenghui Liu Chengqiang Ding Ganghua Li | 2015 | The Crop Journal2015，3，1： | 2 |
| 3 | 水稻再生苗后期耐寒生理特性研究显示文摘为了明确水稻再生后期耐寒生理生化特性,以东乡野生稻、淮稻9号和籼稻9311等6个水稻品种为试验材料。在水稻再生苗后期,测定了5项耐寒性生理指标。结果显示:1野生稻表现为极度耐寒,其叶绿素、脯氨酸、可溶性糖和蛋白等4项指标均表现最高值,电导率表现最低值;2籼稻9311表现出极为冷敏感,其各项生理生化指标值排名与野生稻正好相反;3热粳35、糯稻89-1、武运粳24和淮稻9号表现出不同程度耐寒性,其生理指标值界于野生稻与籼稻9311之间。研究表明,述生理生化指标可用来作为耐寒越冬水稻材料筛选的标准。同时,野生稻可作为耐寒越冬基因挖掘和培育耐寒越冬稻新品种的重要基因资源。 | 周军杰 郑剑 李兴星 南文斌 杨永清 张汉马 梁永书 | 2016 | 西南农业学报2016，29，4： | 2 |
| 4 | 湖南怀化花洋溪村“贡田”稻米品质的影响因素分析显示文摘【目的】湖南怀化市花洋溪村“贡田”生产的稻米品质优良,历史上一直作为贡品。我们研究了品种和“贡田”的理化性状和环境,以分析形成优质稻米的影响因素。【方法】在湖南怀化市花洋溪村的“贡田”与非贡田中采集0-20 cm耕层土样,测定土壤有机碳、全量及速效氮磷养分含量。在两块田中同时种植了‘禾中香’、‘穗晚香’、‘农香25’ 3个水稻品种,测定了灌溉水、稻谷和土壤的22种元素含量,分析了稻米的食味品质(外观、黏度、硬度、平衡度、食味值)及营养品质(蛋白质、脂肪、淀粉)。通过冗余分析、结构方程模型等方法,解析“贡田”对水稻食味及营养品质的影响。【结果】与非贡田相比,“贡田”土壤有机质、全氮、全磷、速效钾、有效磷含量,微生物量碳、微生物量氮、微生物量磷含量,以及铁、铝含量均明显较高。“贡田”中生长的水稻籽粒中含有较高的锌、铷、锶含量和较高的脂肪含量(营养品质),而稻米的食味品质(黏度、外观及食味值)则更多地取决于水稻品种。冗余分析结果显示,土壤全量养分、速效养分及微生物生物量解释了59%的水稻食味及营养品质差异。结构方程模型显示,土壤中22种元素含量与水稻中的相应元素含量显著正相关。灌溉水元素含量较少,对稻米食味及营养品质影响也较小。【结论】“贡田”通过长期施用有机肥显著提高了土壤有机质和氮、磷、钾含量,维持了较好的土壤生物性状,因此,在同样施肥量下,可显著提高水稻的产量和营养品质。相比于土壤肥力,稻米品种特性决定着稻米的食味品质及其对土壤肥力的响应。依据当下的施肥量和施肥方法 (含秸秆还田),稻米中较高的脂肪含量和较低的蛋白含量均有助于稻米食味值的增加。因此,维持高的土壤肥力和适当的施肥水平,是获得优质稻米和较高产量的关键。 | 赵紫薇 欧张丹 田茂平 赵书慧 陈玉梅 张振华 | 2023 | 植物营养与肥料学报2023，29，2： | 0 |
