| 摘 要： | 以番茄、黄瓜、苜蓿、白蜡等园艺作物和小麦、玉米、棉花等大田作物的幼苗在氯化钠胁迫下其发芽率,发芽势,成苗率,下胚轴长、粗、重,子叶重,叶片含水量及矿质元素含量,MDA,POD,SOD的变化为基础,详细地阐述了园艺作物种子萌发,幼苗的形态及生理变化,与此同时,对由于土壤次生盐渍化所带来的问题进行了简单介绍,最后指出在作物抗盐性研究上可能的发展方向.

| Abstract: | Took horticultural crops such as tomatoes, cucumbers, alfalfa, wax and wheat, maize, cotton and other field crops as materials, the germination, seedling morphological characteristic and phys- iology change of horticultural crops were clarified. This paper mainly studied the germination rate, germination vigor, seedling rate, water content in leaves, mineral substance content and MDA,POD, SOD etc. Meanwhile, it also introduced the problems caused by soil salinization, pointed out the development of crop resistance salinization study. |
