实验进行了克隆的茄andigena，这需要短的光周期的块茎，以调查是否块茎涉及特定的刺激。结果表明，块茎化刺激可以通过诱导嫁接到非诱导的枝条上来传递，并且即使是来自诱导植物的小块茎也能够传递刺激。这些和其他实验的结果支持了这样一种观点，即块茎形成是由特定的刺激决定的，而不是由非特异性的光合作用决定的。结果表明，刺激可以移动basipetally和acropetally，但块茎的发展只发生在物理上最低的茎插节，无论这些是正常取向或倒置。
Experiments were carried out with a clone ofSolanum andigena, which requires short photo‐periods for tuberization, to investigate whether or not tuberization involves a specific stimulus. It was shown that a tuberization stimulus can be transmitted by grafting induced on to non‐induced shoots and that even small pieces of stem from induced plants are capable of transmitting the stimulus. The results of these and other experiments support the view that tuberization is determined by a specific stimulus, rather than by the availability of non‐specific photosynthates. It is shown that the stimulus can move both basipetally and acropetally, but tuber development occurs only at the physically lowest nodes of stem cuttings, whether these are normally orientated or inverted.
