| 摘 要： | 通过对马铃薯叶面喷施不同浓度植物生长调节剂(多效唑)和微量元素,研究不同浓度多效唑和微量元素配合喷施对马铃薯叶绿素含量、光合速率、淀粉含量、产量等的影响。结果表明,不同浓度多效唑和微量元素配合使用,可使马铃薯顶端生长受到明显抑制,茎粗增加,叶绿素含量增加,光合速率增加到一定程度有所下降。淀粉含量随着浓度增加而增加,到一定程度也有下降的趋势。

| Abstract: | The effects on chlorophyll content,photosynthesis rate,starch content,and yield of plant growth regulator,Paclobutrazol,applied by foliage spray at a various levels of concentration,and in combination with trace elements,were studied.With use of Paelobutrazol,the plant height was retarded,stem diameter increased, and chlorophyll content enhanced.But photosynthesis rate was increased with increase in Paclobutrazol concentration early and then decreased.The starch content also increased with Paclobutrazol and then deceased. |
