It appeared that the sugarcane leaf segments dedifferentiation and callus formation induced by 2.4-d May be related with the changes of endogenous levels of zeatin, zeatin riboside and ABA.
据此我们认为在甘蔗组织培养中2.4- D可能通过调节内源激素的水平及其相互作用，引起培养物中某些生理生化过程发生改变，从而进行脱分化和愈伤组织形成。
The levels of endogenous Auxin, Zeatin and Zeatin riboside in the middle segment of primary root were all increased obviously by DPC, which might be the key reason for lateral roots induction.
DPC处理提高了幼苗主根中部生长素、玉米素及其核苷含量，可能是诱导侧根发生的内在原因。
