为探明马铃薯源的改变对其生长和产量的影响，采用人工去除顶部和叶片的方法，分析马铃薯叶片叶绿素含量、叶面积、产量和块茎淀粉含量的变化。结果表明：去顶去叶后，与未去顶去叶的对照比较，马铃薯叶片的叶绿素值呈下降趋势，植株叶面积逐渐增加，但整体叶面积仍低于对照；去顶处理的马铃薯产量有所上升，去叶处理的马铃薯产量显著降低；去顶去叶对马铃薯淀粉含量影响不大。
為探明馬鈴藷源的改變對其生長和產量的影響，採用人工去除頂部和葉片的方法，分析馬鈴藷葉片葉綠素含量、葉麵積、產量和塊莖澱粉含量的變化。結果錶明：去頂去葉後，與未去頂去葉的對照比較，馬鈴藷葉片的葉綠素值呈下降趨勢，植株葉麵積逐漸增加，但整體葉麵積仍低于對照；去頂處理的馬鈴藷產量有所上升，去葉處理的馬鈴藷產量顯著降低；去頂去葉對馬鈴藷澱粉含量影響不大。

The chlorophyll content,leaf area,yield and tuber starch content of potato plants under topping and defoliation at bud stage were analyzed to study the effects of topping and defoliation at bud stage on growth and yield of potato.The results showed that:1 )The chlorophyll content presents a decline trend after topping and defoliation compared with CK,and leaf area increases gradually but the overall leaf area still lower than CK;2 )Topping can increase potato yield but defoliation reduces potato yield significantly;3)Topping and defoliation has no effect on starch content of potato.
