A previous study (Hsieh and Tung 2001) has shown that cytokinin and related compounds such as adenine (Ade), adenosine monophosphate (AMP), and dihydrozeatin (DHZ) can effectively promote seedling growth of rice (cv. Tai-keng 3) in the summer.

In this study, we found that nucleotide cytokinins such as benzyladenosine 5-onophosphate (BARMP), zeatin ribonucleoside(ZR), zeatin ribonucleoside 5-monophosphate (ZRMP), and dihydrozeatin ribonucleoside 5-monophosphate (DHZRMP) are more effective than their free-base counterparts in promoting seedling growth in Tai-keng 3.
