摘要 烟叶的钾含量是评价烟叶质量的重要指标。我国烟叶含钾量普遍较低,选育钾高效基因型烟草品种(系)是提高我国烟叶钾含量的理想方法。介绍了我国烟叶钾含量的现状,综述了烤烟钾高效基因型的选育及其钾素吸收机理、钾素积累、分配规律等钾素营养特性的研究进展,并对通过选育钾高效基因型品种来提高我国烟叶钾含量的前景进行了展望。 The potassium content in tobacco is an important indicator to evaluate the quality of tobacco leaves.The potassium content in tobacco is generally low in China,so breeding tobacco varieties which had efficient potassium utilization ability is the ideal way to solve the problem.The present situation of the potassium content of tobacco in China was introduced,the advances in breeding of potassium-efficient genotypes tobacco and mechanism of absorption,accumulation of tobacco and distribution of potassium nutrition were reviewed.Finally,the development foreground that to increase the potassium content of tobacco in China by breeding the potassium-efficient genotypes tobacco was prospected.
