摘　　要：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。The relationship of potato tuber yield with endogenous hormones in leaves of Potato varieties ‘Jinshu 2’,‘Neishu 3’and‘Zihuabai’was studied . The results showed: the tuber yield was positively correlated with the content of ABA in the leaves and negatively correlated with ratios of GA3/ABA,IAA/ABA and CTK/ABAThe variety with a high ABA content in leaves, high GA3/ABA, IAA/ABA　CTK/ABA ratios of leaf in tuber formation stage, and high IAA and ABA contents in leaves in starch accumulation stage, had an early tuber formation, a high yield increase rate and high yield.
