氮素 水稻 Nipponbare OM052 氮肥利用率
2023/2/27
氮素是植物生长发育所需的大量元素之一，水稻是我国的主要粮食作物，水稻生产对氮的需求仅次于水，是构成水稻生长成本的主要部分。目前，水稻氮肥表观利用率只有39%，即施氮肥量的50%以上残留在环境中。因此，在保证产量不减的基础上如何提高氮肥的利用效率，减少氮肥的使用量是我国农业可持续发展亟待解决的重要问题。

Variability in the oligosaccharide concentration in seeds of the mapping population of pea (Pisum sativum L.)
genetic map molecular markers QTL rugosus (r) locus seed oligosaccharide
2014/7/9
Anti-nutritional compounds are among the obstacles to the use of pea seeds as a protein source in both feed and food. These compounds are poorly digested by both monogastric animals and humans. There ...
QTL mapping for ear length and ear diameter under different nitrogen regimes in maize
Maize (Zea mays L.) ear length ear diameter quantitative trait locus
2011/1/10
Ear length (EL) and ear diameter (ED) are two of the most important traits in maize (Zea mays L.), related to yield and plant morphology. In this study, an F9 recombinant inbred line (RIL) population ...
