用虎头（Ｈ）、克四（Ｋ）和Ｆａｖｏｒｉｔａ（Ｆ）３个马铃薯（ＳｏｌａｎｕｍｔｕｂｅｒｏｓｕｍＬ．）品种的无病毒再生植株进行的微型薯诱导实验表明，微型薯的诱导与植物激素的种类和浓度有关：３个品种的微型薯诱导都需要ＢＡ，但０．０５ｍｇ·Ｌ－１的ＩＢＡ能缩短Ｈ微型薯诱导所需的时间，而０．０５ｍｇ·Ｌ－１的ＮＡＡ有利于Ｋ在形成的微型薯上再产生新的微型薯，即形成二次微型薯．另外，０．０５ｍｇ·Ｌ－１的ＩＢＡ能够明显地提高Ｆ微型薯的生长量．对此３个品种而言，在１．０ｍｇ·ＬＢＡ＋０．５ｍｇ·Ｌ－１ＩＢＡ的激素溶液中预处理后的微型薯，在有菌条件下，比对照组更容易萌发形成再生植株．
Microtuber induction experiments with virus-free regenerated plants of the three potato (Solanum tuberosum L.) varieties of tiger-head (H), g (K) and Favorita (F) showed that the induction of microtubers was related to the type and concentration of plant hormones BA was required for the induction of miniature tuber of three cultivars, but IBA of 0.05mg · L-1 could shorten the time needed for inducing H-miniature tubercle while NAA of 0.05mg · L-1 was beneficial to the formation of miniature A new miniature potato is produced on the potato, ie, a second miniature potato is formed. In addition, 0.05mg · L-1 of IBA can significantly improve the F microtuber growth. For the three cultivars, the microtuber pretreated in 1.0 mg · LBA + 0.5 mg · L-1 IBA hormone solution could germinate more easily than the control group under the conditions of bacteria.
