| 摘 要： | 以"青芋2号"菊芋为试材,研究了菊芋苗期缺钾的主要症状及生理特性。结果表明:缺素症状在前期并不明显仅表现为生长减缓,处理20 d以后缺素症状由底向上开始出现,处理40 d后生长几乎停止;可溶性蛋白含量先上升后降低,叶绿素含量先升高后下降,均高于对照,根系活力开始有明显上升,之后迅速下降。蛋白含量、根系活力在缺钾初期的上升认为与植物缺钾适应性调节有关。

| Abstract: | Taking 'Qingyu No.2' as test material,the main symptoms of potassium deficiency and physiological characteristics in potted seedlings of Helianthus tuberosul L.were studied.The results showed that deficiency symptom was not obvious,at the early stage only showed slow growth,20 days after treatment deficiency symptom appeared from the bottom up,dealing with growth virtually ceased after 40 days;soluble protein content increased and then decreased,chlorophyll content first increased and then decreased,higher ... |
