摘要： 以晋薯2号、紫花白、内薯3号为材料，系统研究了马铃薯生育期间块茎内源激素变化与块茎增大生长的关系，结果表明，ABA含量变化与块茎的增大呈极显着的正相关，与块茎增大速率变化呈极显着的负相关；GA₃,IAA,CTK含量变化与块茎增大和块茎增大速率变化没有明显的相关性；GA₃/ABA,IAA/ABA,CTK/ABA的变化与块茎增大呈较显着的负相关，与块茎增大速率变化呈较显着的正相关。生育前期GA₃、IAA含量高而ABA含量低的品种，块茎形成早，增大快，块茎大。

Abstract: The relationship between the change of intrinsic hormones in tuber of potato and growth of the tuber at the growing period was investigated systematically by using materials of Jinshu 2,Zihuabai,Neishu 3.The results showed that the change of ABA content with increment of the tuber was significantly positive correlation,and with the increment rate of the tuber was significantly negative correlation.The change of GA₃ ,IAA,CTK content with the growth of the tuber had no marked correlated character.The change of GA₃ /ABA,IAA/ABA and CTK/ABA with the increment of the tuber had a significantly negative correlation,and with the change of increment rate had a significantly positive correlation.The tuber that the breed had a high content of GA₃ ,IAA and low content of ABA in the earlier stage of the growth was formed early and was increased fast,the tuber was bigger.

Key words: Potato, Increment of the tuber, Intrinsic hormone
