选用晋薯２号、内薯３号、紫花白３个品种为材料，对马铃薯生育期间叶片内源ＧＡ３、ＩＡＡ、ＣＴＫ、ＡＢＡ的含量变化与块茎产量形成的相互关系进行了研究。结果表明：不同生育时期ＡＢＡ含量与块茎产量呈极显著的正相关，ＧＡ３／ＡＢＡ、ＩＡＡ／ＡＢＡ、ＣＴＫ／ＡＢＡ３个比值变化与块茎产量和产量增长速率呈负相关。在块茎形成期ＡＢＡ含量低，ＧＡ３／ＡＢＡ、ＩＡＡ／ＡＢＡ、ＣＴＫ／ＡＢＡ比值大，淀粉积累期ＩＡＡ含量高，ＡＢＡ含量高的品种，块茎产量高、产量增长速率块、产量形成早。
Three varieties of Jinshu 2, Neishu 3 and Zihuabai were selected as materials to study the relationship between changes of leaf endogenous GA3, IAA, CTK and ABA content and tuber yield formation during potato growth. The results showed that there was a significant positive correlation between ABA content and tuber yield at different growth stages. The ratio of GA3 / ABA, IAA / ABA and CTK / ABA was negatively correlated with tuber yield and yield growth rate. The varieties with low ABA content, high GA3 / ABA, IAA / ABA, CTK / ABA, high IAA content during starch accumulation and high ABA content had high tuber yield and yield growth rate and early yield.
